Path
interface Path : Comparable<Path!>, MutableIterable<Path!>, Watchable
java.nio.file.Path |
An object that may be used to locate a file in a file system. It will typically represent a system dependent file path.
A Path
represents a path that is hierarchical and composed of a sequence of directory and file name elements separated by a special separator or delimiter. A root component, that identifies a file system hierarchy, may also be present. The name element that is farthest from the root of the directory hierarchy is the name of a file or directory. The other name elements are directory names. A Path
can represent a root, a root and a sequence of names, or simply one or more name elements. A Path
is considered to be an empty path if it consists solely of one name element that is empty. Accessing a file using an empty path is equivalent to accessing the default directory of the file system. Path
defines the getFileName
, getParent
, getRoot
, and subpath
methods to access the path components or a subsequence of its name elements.
In addition to accessing the components of a path, a Path
also defines the resolve
and resolveSibling
methods to combine paths. The relativize
method that can be used to construct a relative path between two paths. Paths can be compared
, and tested against each other using the #startsWith and #endsWith methods.
This interface extends Watchable
interface so that a directory located by a path can be #register with a WatchService
and entries in the directory watched.
WARNING: This interface is only intended to be implemented by those developing custom file system implementations. Methods may be added to this interface in future releases.
Accessing Files
Paths may be used with the Files
class to operate on files, directories, and other types of files. For example, suppose we want a to read text from a file "access.log
". The file is located in a directory "logs
" relative to the current working directory and is UTF-8 encoded.
Path path = FileSystems.getDefault().getPath("logs", "access.log"); BufferedReader reader = Files.newBufferedReader(path, StandardCharsets.UTF_8);
Interoperability
Paths associated with the default are generally interoperable with the java.io.File
class. Paths created by other providers are unlikely to be interoperable with the abstract path names represented by java.io.File
. The toPath
method may be used to obtain a Path
from the abstract path name represented by a java.io.File
object. The resulting Path
can be used to operate on the same file as the java.io.File
object. In addition, the toFile
method is useful to construct a File
from the String
representation of a Path
.
Concurrency
Implementations of this interface are immutable and safe for use by multiple concurrent threads.

Public methods
compareTo
abstract fun compareTo(other: Path!): Int
Compares two abstract paths lexicographically. The ordering defined by this method is provider specific, and in the case of the default provider, platform specific. This method does not access the file system and neither file is required to exist.
This method may not be used to compare paths that are associated with different file system providers.
Parameters | |
---|---|
o |
the object to be compared. |
other |
Path!: the path compared to this path. |
Return | |
---|---|
Int |
zero if the argument is equal to this path, a value less than zero if this path is lexicographically less than the argument, or a value greater than zero if this path is lexicographically greater than the argument |
Exceptions | |
---|---|
java.lang.NullPointerException |
if the specified object is null |
java.lang.ClassCastException |
if the paths are associated with different providers |
endsWith
abstract fun endsWith(other: Path!): Boolean
Tests if this path ends with the given path.
If the given path has N elements, and no root component, and this path has N or more elements, then this path ends with the given path if the last N elements of each path, starting at the element farthest from the root, are equal.
If the given path has a root component then this path ends with the given path if the root component of this path ends with the root component of the given path, and the corresponding elements of both paths are equal. Whether or not the root component of this path ends with the root component of the given path is file system specific. If this path does not have a root component and the given path has a root component then this path does not end with the given path.
If the given path is associated with a different FileSystem
to this path then false
is returned.
Parameters | |
---|---|
other |
Path!: the given path |
Return | |
---|---|
Boolean |
true if this path ends with the given path; otherwise false |
endsWith
abstract fun endsWith(other: String!): Boolean
Tests if this path ends with a Path
, constructed by converting the given path string, in exactly the manner specified by the endsWith(Path)
method. On UNIX for example, the path "foo/bar
" ends with "foo/bar
" and "bar
". It does not end with "r
" or "/bar
". Note that trailing separators are not taken into account, and so invoking this method on the Path
"foo/bar
" with the String
"bar/
" returns true
.
Parameters | |
---|---|
other |
String!: the given path string |
Return | |
---|---|
Boolean |
true if this path ends with the given path; otherwise false |
Exceptions | |
---|---|
java.nio.file.InvalidPathException |
If the path string cannot be converted to a Path. |
getFileName
abstract fun getFileName(): Path!
Returns the name of the file or directory denoted by this path as a Path
object. The file name is the farthest element from the root in the directory hierarchy.
Return | |
---|---|
Path! |
a path representing the name of the file or directory, or null if this path has zero elements |
getFileSystem
abstract fun getFileSystem(): FileSystem!
Returns the file system that created this object.
Return | |
---|---|
FileSystem! |
the file system that created this object |
getName
abstract fun getName(index: Int): Path!
Returns a name element of this path as a Path
object.
The index
parameter is the index of the name element to return. The element that is closest to the root in the directory hierarchy has index 0
. The element that is farthest from the root has index count
-1
.
Parameters | |
---|---|
index |
Int: the index of the element |
Return | |
---|---|
Path! |
the name element |
Exceptions | |
---|---|
java.lang.IllegalArgumentException |
if index is negative, index is greater than or equal to the number of elements, or this path has zero name elements |
getNameCount
abstract fun getNameCount(): Int
Returns the number of name elements in the path.
Return | |
---|---|
Int |
the number of elements in the path, or 0 if this path only represents a root component |
getParent
abstract fun getParent(): Path!
Returns the parent path, or null
if this path does not have a parent.
The parent of this path object consists of this path's root component, if any, and each element in the path except for the farthest from the root in the directory hierarchy. This method does not access the file system; the path or its parent may not exist. Furthermore, this method does not eliminate special names such as "." and ".." that may be used in some implementations. On UNIX for example, the parent of "/a/b/c
" is "/a/b
", and the parent of "x/y/.
" is "x/y
". This method may be used with the normalize
method, to eliminate redundant names, for cases where shell-like navigation is required.
If this path has one or more elements, and no root component, then this method is equivalent to evaluating the expression:
subpath(0, getNameCount()-1);
Return | |
---|---|
Path! |
a path representing the path's parent |
getRoot
abstract fun getRoot(): Path!
Returns the root component of this path as a Path
object, or null
if this path does not have a root component.
Return | |
---|---|
Path! |
a path representing the root component of this path, or null |
isAbsolute
abstract fun isAbsolute(): Boolean
Tells whether or not this path is absolute.
An absolute path is complete in that it doesn't need to be combined with other path information in order to locate a file.
Return | |
---|---|
Boolean |
true if, and only if, this path is absolute |
iterator
abstract fun iterator(): MutableIterator<Path!>
Returns an iterator over the name elements of this path.
The first element returned by the iterator represents the name element that is closest to the root in the directory hierarchy, the second element is the next closest, and so on. The last element returned is the name of the file or directory denoted by this path. The root
component, if present, is not returned by the iterator.
Return | |
---|---|
MutableIterator<Path!> |
an iterator over the name elements of this path. |
normalize
abstract fun normalize(): Path!
Returns a path that is this path with redundant name elements eliminated.
The precise definition of this method is implementation dependent but in general it derives from this path, a path that does not contain redundant name elements. In many file systems, the ".
" and "..
" are special names used to indicate the current directory and parent directory. In such file systems all occurrences of ".
" are considered redundant. If a "..
" is preceded by a non-"..
" name then both names are considered redundant (the process to identify such names is repeated until it is no longer applicable).
This method does not access the file system; the path may not locate a file that exists. Eliminating "..
" and a preceding name from a path may result in the path that locates a different file than the original path. This can arise when the preceding name is a symbolic link.
Return | |
---|---|
Path! |
the resulting path or this path if it does not contain redundant name elements; an empty path is returned if this path does have a root component and all name elements are redundant |

of
open static fun of(
first: String!,
vararg more: String!
): Path!
Returns a Path
by converting a path string, or a sequence of strings that when joined form a path string. If more
does not specify any elements then the value of the first
parameter is the path string to convert. If more
specifies one or more elements then each non-empty string, including first
, is considered to be a sequence of name elements and is joined to form a path string. The details as to how the Strings are joined is provider specific but typically they will be joined using the name-separator
as the separator. For example, if the name separator is "/
" and getPath("/foo","bar","gus")
is invoked, then the path string "/foo/bar/gus"
is converted to a Path
. A Path
representing an empty path is returned if first
is the empty string and more
does not contain any non-empty strings.
The Path
is obtained by invoking the getPath
method of the default
FileSystem
.
Note that while this method is very convenient, using it will imply an assumed reference to the default FileSystem
and limit the utility of the calling code. Hence it should not be used in library code intended for flexible reuse. A more flexible alternative is to use an existing Path
instance as an anchor, such as:
<code>Path dir = ... Path path = dir.resolve("file"); </code>
Parameters | |
---|---|
first |
String!: the path string or initial part of the path string |
more |
String!: additional strings to be joined to form the path string |
Return | |
---|---|
Path! |
the resulting Path |
Exceptions | |
---|---|
java.nio.file.InvalidPathException |
if the path string cannot be converted to a Path |

of
open static fun of(uri: URI!): Path!
Returns a by converting a URI.
This method iterates over the installed
providers to locate the provider that is identified by the URI scheme
of the given URI. URI schemes are compared without regard to case. If the provider is found then its getPath
method is invoked to convert the URI.
In the case of the default provider, identified by the URI scheme "file", the given URI has a non-empty path component, and undefined query and fragment components. Whether the authority component may be present is platform specific. The returned Path
is associated with the default
file system.
The default provider provides a similar round-trip guarantee to the java.io.File
class. For a given Path
p it is guaranteed that
Path.of(
p.
toUri
()).equals(
p.
toAbsolutePath
())
so long as the original Path
, the URI
, and the new Path
are all created in (possibly different invocations of) the same Java virtual machine. Whether other providers make any guarantees is provider specific and therefore unspecified.
Parameters | |
---|---|
uri |
URI!: the URI to convert |
Return | |
---|---|
Path! |
the resulting Path |
Exceptions | |
---|---|
java.lang.IllegalArgumentException |
if preconditions on the uri parameter do not hold. The format of the URI is provider specific. |
java.nio.file.FileSystemNotFoundException |
The file system, identified by the URI, does not exist and cannot be created automatically, or the provider identified by the URI's scheme component is not installed |
java.lang.SecurityException |
if a security manager is installed and it denies an unspecified permission to access the file system |
register
abstract fun register(
watcher: WatchService!,
events: Array<WatchEvent.Kind<*>!>!,
vararg modifiers: WatchEvent.Modifier!
): WatchKey!
Registers the file located by this path with a watch service.
In this release, this path locates a directory that exists. The directory is registered with the watch service so that entries in the directory can be watched. The events
parameter is the events to register and may contain the following events:
ENTRY_CREATE
- entry created or moved into the directoryENTRY_DELETE
- entry deleted or moved out of the directoryENTRY_MODIFY
- entry in directory was modified
The context
for these events is the relative path between the directory located by this path, and the path that locates the directory entry that is created, deleted, or modified.
The set of events may include additional implementation specific event that are not defined by the enum StandardWatchEventKinds
The modifiers
parameter specifies modifiers that qualify how the directory is registered. This release does not define any standard modifiers. It may contain implementation specific modifiers.
Where a file is registered with a watch service by means of a symbolic link then it is implementation specific if the watch continues to depend on the existence of the symbolic link after it is registered.
Parameters | |
---|---|
watcher |
WatchService!: the watch service to which this object is to be registered |
events |
Array<WatchEvent.Kind<*>!>!: the events for which this object should be registered |
modifiers |
WatchEvent.Modifier!: the modifiers, if any, that modify how the object is registered |
Return | |
---|---|
WatchKey! |
a key representing the registration of this object with the given watch service |
Exceptions | |
---|---|
java.lang.UnsupportedOperationException |
if unsupported events or modifiers are specified |
java.lang.IllegalArgumentException |
if an invalid combination of events or modifiers is specified |
java.nio.file.ClosedWatchServiceException |
if the watch service is closed |
java.io.IOException |
if an I/O error occurs |
java.lang.SecurityException |
In the case of the default provider, and a security manager is installed, the checkRead method is invoked to check read access to the file. |
java.nio.file.NotDirectoryException |
if the file is registered to watch the entries in a directory and the file is not a directory (optional specific exception) |
register
abstract fun register(
watcher: WatchService!,
vararg events: WatchEvent.Kind<*>!
): WatchKey!
Registers the file located by this path with a watch service.
An invocation of this method behaves in exactly the same way as the invocation
watchable.<code><a docref="java.nio.file.Path$register(java.nio.file.WatchService, kotlin.Array((java.nio.file.WatchEvent.Kind((kotlin.Any)))), kotlin.Array((java.nio.file.WatchEvent.Modifier)))">register</a></code>(watcher, events, new WatchEvent.Modifier[0]);
Usage Example: Suppose we wish to register a directory for entry create, delete, and modify events:
Path dir = ... WatchService watcher = ... WatchKey key = dir.register(watcher, ENTRY_CREATE, ENTRY_DELETE, ENTRY_MODIFY);
Parameters | |
---|---|
watcher |
WatchService!: The watch service to which this object is to be registered |
events |
WatchEvent.Kind<*>!: The events for which this object should be registered |
Return | |
---|---|

java.lang.SecurityException |
In the case of the default provider, and a security manager is installed, the checkRead method is invoked to check read access to the file. |
java.nio.file.NotDirectoryException |
If the file is registered to watch the entries in a directory and the file is not a directory (optional specific exception) |
relativize
abstract fun relativize(other: Path!): Path!
Constructs a relative path between this path and a given path.
Relativization is the inverse of resolution
. This method attempts to construct a relative
path that when resolved
against this path, yields a path that locates the same file as the given path. For example, on UNIX, if this path is "/a/b"
and the given path is "/a/b/c/d"
then the resulting relative path would be "c/d"
. Where this path and the given path do not have a root
component, then a relative path can be constructed. A relative path cannot be constructed if only one of the paths have a root component. Where both paths have a root component then it is implementation dependent if a relative path can be constructed. If this path and the given path are equal
then an empty path is returned.
For any two normalized
paths p and q, where q does not have a root component,
When symbolic links are supported, then whether the resulting path, when resolved against this path, yields a path that can be used to locate the same
file as other
is implementation dependent. For example, if this path is "/a/b"
and the given path is "/a/x"
then the resulting relative path may be "../x"
. If "b"
is a symbolic link then is implementation dependent if "a/b/../x"
would locate the same file as "/a/x"
.
Parameters | |
---|---|
other |
Path!: the path to relativize against this path |
Return | |
---|---|
Path! |
the resulting relative path, or an empty path if both paths are equal |
Exceptions | |
---|---|
java.lang.IllegalArgumentException |
if other is not a Path that can be relativized against this path |
resolve
abstract fun resolve(other: Path!): Path!
Resolve the given path against this path.
If the other
parameter is an absolute
path then this method trivially returns other
. If other
is an empty path then this method trivially returns this path. Otherwise this method considers this path to be a directory and resolves the given path against this path. In the simplest case, the given path does not have a root
component, in which case this method joins the given path to this path and returns a resulting path that #endsWith with the given path. Where the given path has a root component then resolution is highly implementation dependent and therefore unspecified.
Parameters | |
---|---|
other |
Path!: the path to resolve against this path |
Return | |
---|---|
Path! |
the resulting path |
See Also
resolve
abstract fun resolve(other: String!): Path!
Converts a given path string to a Path
and resolves it against this Path
in exactly the manner specified by the resolve
method. For example, suppose that the name separator is "/
" and a path represents "foo/bar
", then invoking this method with the path string "gus
" will result in the Path
"foo/bar/gus
".
Parameters | |
---|---|
other |
String!: the path string to resolve against this path |
Return | |
---|---|
Path! |
the resulting path |
Exceptions | |
---|---|
java.nio.file.InvalidPathException |
if the path string cannot be converted to a Path. |
See Also
resolveSibling
abstract fun resolveSibling(other: Path!): Path!
Resolves the given path against this path's parent
path. This is useful where a file name needs to be replaced with another file name. For example, suppose that the name separator is "/
" and a path represents "dir1/dir2/foo
", then invoking this method with the Path
"bar
" will result in the Path
"dir1/dir2/bar
". If this path does not have a parent path, or other
is absolute
, then this method returns other
. If other
is an empty path then this method returns this path's parent, or where this path doesn't have a parent, the empty path.
Parameters | |
---|---|
other |
Path!: the path to resolve against this path's parent |
Return | |
---|---|
Path! |
the resulting path |
See Also
resolveSibling
abstract fun resolveSibling(other: String!): Path!
Converts a given path string to a Path
and resolves it against this path's parent
path in exactly the manner specified by the resolveSibling
method.
Parameters | |
---|---|
other |
String!: the path string to resolve against this path's parent |
Return | |
---|---|
Path! |
the resulting path |
Exceptions | |
---|---|
java.nio.file.InvalidPathException |
if the path string cannot be converted to a Path. |

startsWith
abstract fun startsWith(other: Path!): Boolean
Tests if this path starts with the given path.
This path starts with the given path if this path's root component starts with the root component of the given path, and this path starts with the same name elements as the given path. If the given path has more name elements than this path then false
is returned.
Whether or not the root component of this path starts with the root component of the given path is file system specific. If this path does not have a root component and the given path has a root component then this path does not start with the given path.
If the given path is associated with a different FileSystem
to this path then false
is returned.
Parameters | |
---|---|
other |
Path!: the given path |
Return | |
---|---|
Boolean |
true if this path starts with the given path; otherwise false |
startsWith
abstract fun startsWith(other: String!): Boolean
Tests if this path starts with a Path
, constructed by converting the given path string, in exactly the manner specified by the startsWith(Path)
method. On UNIX for example, the path "foo/bar
" starts with "foo
" and "foo/bar
". It does not start with "f
" or "fo
".
Parameters | |
---|---|
other |
String!: the given path string |
Return | |
---|---|
Boolean |
true if this path starts with the given path; otherwise false |
Exceptions | |
---|---|
java.nio.file.InvalidPathException |
If the path string cannot be converted to a Path. |
subpath
abstract fun subpath(
beginIndex: Int,
endIndex: Int
): Path!
Returns a relative Path
that is a subsequence of the name elements of this path.
The beginIndex
and endIndex
parameters specify the subsequence of name elements. The name that is closest to the root in the directory hierarchy has index 0
. The name that is farthest from the root has index count
-1
. The returned Path
object has the name elements that begin at beginIndex
and extend to the element at index endIndex-1
.
Parameters | |
---|---|
beginIndex |
Int: the index of the first element, inclusive |
endIndex |
Int: the index of the last element, exclusive |
Return | |
---|---|
Path! |
a new Path object that is a subsequence of the name elements in this Path |
Exceptions | |
---|---|
java.lang.IllegalArgumentException |
if beginIndex is negative, or greater than or equal to the number of elements. If endIndex is less than or equal to beginIndex , or larger than the number of elements. |
toAbsolutePath
abstract fun toAbsolutePath(): Path!
Returns a Path
object representing the absolute path of this path.
If this path is already absolute
then this method simply returns this path. Otherwise, this method resolves the path in an implementation dependent manner, typically by resolving the path against a file system default directory. Depending on the implementation, this method may throw an I/O error if the file system is not accessible.
Return | |
---|---|
Path! |
a Path object representing the absolute path |
Exceptions | |
---|---|
java.io.IOError |
if an I/O error occurs |
java.lang.SecurityException |
In the case of the default provider, a security manager is installed, and this path is not absolute, then the security manager's checkPropertyAccess method is invoked to check access to the system property user.dir |
toFile
abstract fun toFile(): File!
Returns a File
object representing this path. Where this Path
is associated with the default provider, then this method is equivalent to returning a File
object constructed with the String
representation of this path.
If this path was created by invoking the File
toPath
method then there is no guarantee that the File
object returned by this method is equal
to the original File
.
Return | |
---|---|
File! |
a File object representing this path |
Exceptions | |
---|---|
java.lang.UnsupportedOperationException |
if this Path is not associated with the default provider |
toRealPath
abstract fun toRealPath(vararg options: LinkOption!): Path!
Returns the real path of an existing file.
The precise definition of this method is implementation dependent but in general it derives from this path, an absolute
path that locates the same
file as this path, but with name elements that represent the actual name of the directories and the file. For example, where filename comparisons on a file system are case insensitive then the name elements represent the names in their actual case. Additionally, the resulting path has redundant name elements removed.
If this path is relative then its absolute path is first obtained, as if by invoking the toAbsolutePath
method.
The options
array may be used to indicate how symbolic links are handled. By default, symbolic links are resolved to their final target. If the option NOFOLLOW_LINKS
is present then this method does not resolve symbolic links. Some implementations allow special names such as "..
" to refer to the parent directory. When deriving the real path, and a "..
" (or equivalent) is preceded by a non-"..
" name then an implementation will typically cause both names to be removed. When not resolving symbolic links and the preceding name is a symbolic link then the names are only removed if it guaranteed that the resulting path will locate the same file as this path.
Parameters | |
---|---|
options |
LinkOption!: options indicating how symbolic links are handled |
Return | |
---|---|
Path! |
an absolute path represent the real path of the file located by this object |
Exceptions | |
---|---|
java.io.IOException |
if the file does not exist or an I/O error occurs |
java.lang.SecurityException |
In the case of the default provider, and a security manager is installed, its checkRead method is invoked to check read access to the file, and where this path is not absolute, its checkPropertyAccess method is invoked to check access to the system property user.dir |
toUri
abstract fun toUri(): URI!
Returns a URI to represent this path.
This method constructs an absolute URI
with a scheme
equal to the URI scheme that identifies the provider. The exact form of the scheme specific part is highly provider dependent.
In the case of the default provider, the URI is hierarchical with a path
component that is absolute. The query and fragment components are undefined. Whether the authority component is defined or not is implementation dependent. There is no guarantee that the URI
may be used to construct a java.io.File
. In particular, if this path represents a Universal Naming Convention (UNC) path, then the UNC server name may be encoded in the authority component of the resulting URI. In the case of the default provider, and the file exists, and it can be determined that the file is a directory, then the resulting URI
will end with a slash.
The default provider provides a similar round-trip guarantee to the java.io.File
class. For a given Path
p it is guaranteed that
Paths.get
(p.toUri()).equals(p .toAbsolutePath
()) so long as the original Path
, the URI
, and the new Path
are all created in (possibly different invocations of) the same Java virtual machine. Whether other providers make any guarantees is provider specific and therefore unspecified.
When a file system is constructed to access the contents of a file as a file system then it is highly implementation specific if the returned URI represents the given path in the file system or it represents a compound URI that encodes the URI of the enclosing file system. A format for compound URIs is not defined in this release; such a scheme may be added in a future release.
Return | |
---|---|
URI! |
the URI representing this path |
Exceptions | |
---|---|
