asList

@SafeVarargs static fun <T : Any!> asList(vararg a: T): MutableList<T>

Returns a fixed-size list backed by the specified array. Changes made to the array will be visible in the returned list, and changes made to the list will be visible in the array. The returned list is Serializable and implements RandomAccess.

The returned list implements the optional Collection methods, except those that would change the size of the returned list. Those methods leave the list unchanged and throw UnsupportedOperationException.

If the specified array's actual component type differs from the type parameter T, this can result in operations on the returned list throwing an ArrayStoreException.

Parameters
`<T>`	the class of the objects in the array
`a`	T: the array by which the list will be backed

Return
`MutableList<T>`	a list view of the specified array

Exceptions
`java.lang.NullPointerException`	if the specified array is `null`

    toIndex: Int, 
    key: T, 
    c: Comparator<in T>?
): Int

Searches a range of the specified array for the specified object using the binary search algorithm. The range must be sorted into ascending order according to the specified comparator (as by the sort(T[], int, int, Comparator) method) prior to making this call. If it is not sorted, the results are undefined. If the range contains multiple elements equal to the specified object, there is no guarantee which one will be found.

Parameters
`<T>`	the class of the objects in the array
`a`	Array<T>: the array to be searched
`fromIndex`	Int: the index of the first element (inclusive) to be searched
`toIndex`	Int: the index of the last element (exclusive) to be searched
`key`	T: the value to be searched for
`c`	Comparator<in T>?: the comparator by which the array is ordered. A `null` value indicates that the elements' natural ordering should be used.

Return

Int index of the search key, if it is contained in the array within the specified range; otherwise, (-(insertion point) - 1). The insertion point is defined as the point at which the key would be inserted into the array: the index of the first element in the range greater than the key, or toIndex if all elements in the range are less than the specified key. Note that this guarantees that the return value will be >= 0 if and only if the key is found.

Return
`Int`	index of the search key, if it is contained in the array within the specified range; otherwise, `(-(insertion point) - 1)`. The insertion point is defined as the point at which the key would be inserted into the array: the index of the first element in the range greater than the key, or `toIndex` if all elements in the range are less than the specified key. Note that this guarantees that the return value will be >= 0 if and only if the key is found.

Exceptions
`java.lang.ClassCastException`	if the range contains elements that are not mutually comparable using the specified comparator, or the search key is not comparable to the elements in the range using this comparator.
`java.lang.IllegalArgumentException`	if `fromIndex > toIndex`
`java.lang.ArrayIndexOutOfBoundsException`	if `fromIndex < 0 or toIndex > a.length`

Added in API level 1

static fun <T : Any!> binarySearch(
    a: Array<T>, 
    key: T, 
    c: Comparator<in T>?
): Int

Searches the specified array for the specified object using the binary search algorithm. The array must be sorted into ascending order according to the specified comparator (as by the sort(T[], Comparator) method) prior to making this call. If it is not sorted, the results are undefined. If the array contains multiple elements equal to the specified object, there is no guarantee which one will be found.

Parameters
`<T>`	the class of the objects in the array
`a`	Array<T>: the array to be searched
`key`	T: the value to be searched for
`c`	Comparator<in T>?: the comparator by which the array is ordered. A `null` value indicates that the elements' natural ordering should be used.

Return

Int index of the search key, if it is contained in the array; otherwise, (-(insertion point) - 1). The insertion point is defined as the point at which the key would be inserted into the array: the index of the first element greater than the key, or a.length if all elements in the array are less than the specified key. Note that this guarantees that the return value will be >= 0 if and only if the key is found.

Exceptions
`java.lang.ClassCastException`	if the array contains elements that are not mutually comparable using the specified comparator, or the search key is not comparable to the elements of the array using this comparator.

static fun compare(
    a: ShortArray?, 
    b: ShortArray?
): Int

Compares two short arrays lexicographically.

If the two arrays share a common prefix then the lexicographic comparison is the result of comparing two elements, as if by Short.compare(short, short), at an index within the respective arrays that is the prefix length. Otherwise, one array is a proper prefix of the other and, lexicographic comparison is the result of comparing the two array lengths. (See mismatch(short[],short[]) for the definition of a common and proper prefix.)

A null array reference is considered lexicographically less than a non-null array reference. Two null array references are considered equal.

The comparison is consistent with equals, more specifically the following holds for arrays a and b:

<code>Arrays.equals(a, b) == (Arrays.compare(a, b) == 0)
  </code>

Parameters
`a`	ShortArray?: the first array to compare
`b`	ShortArray?: the second array to compare

Return
`Int`	the value `0` if the first and second array are equal and contain the same elements in the same order; a value less than `0` if the first array is lexicographically less than the second array; and a value greater than `0` if the first array is lexicographically greater than the second array

    bToIndex: Int
): Int

Compares two Object arrays lexicographically over the specified ranges.

If the two arrays, over the specified ranges, share a common prefix then the lexicographic comparison is the result of comparing two elements of type T at a relative index i within the respective arrays that is the prefix length, as if by:

<code>Comparator.nullsFirst(Comparator.&lt;T&gt;naturalOrder()).
          compare(a[aFromIndex + i, b[bFromIndex + i])
  </code>

Otherwise, one array is a proper prefix of the other and, lexicographic comparison is the result of comparing the two range lengths. (See mismatch(java.lang.Object[],int,int,java.lang.Object[],int,int) for the definition of a common and proper prefix.)

The comparison is consistent with equals, more specifically the following holds for arrays a and b with specified ranges [aFromIndex, aToIndex) and [bFromIndex, bToIndex) respectively:

<code>Arrays.equals(a, aFromIndex, aToIndex, b, bFromIndex, bToIndex) ==
          (Arrays.compare(a, aFromIndex, aToIndex, b, bFromIndex, bToIndex) == 0)

deepEquals

Added in API level 1

static fun deepEquals(
    a1: Array<Any!>?, 
    a2: Array<Any!>?
): Boolean

Returns true if the two specified arrays are deeply equal to one another. Unlike the equals(java.lang.Object[],java.lang.Object[]) method, this method is appropriate for use with nested arrays of arbitrary depth.

Two array references are considered deeply equal if both are null, or if they refer to arrays that contain the same number of elements and all corresponding pairs of elements in the two arrays are deeply equal.

Two possibly null elements e1 and e2 are deeply equal if any of the following conditions hold:

e1 and e2 are both arrays of object reference types, and Arrays.deepEquals(e1, e2) would return true
e1 and e2 are arrays of the same primitive type, and the appropriate overloading of Arrays.equals(e1, e2) would return true.
e1 == e2
e1.equals(e2) would return true.

Note that this definition permits null elements at any depth.

If either of the specified arrays contain themselves as elements either directly or indirectly through one or more levels of arrays, the behavior of this method is undefined.

Parameters
`a1`	Array<Any!>?: one array to be tested for equality
`a2`	Array<Any!>?: the other array to be tested for equality

Return
`Boolean`	`true` if the two arrays are equal

deepHashCode

Added in API level 1

static fun deepHashCode(a: Array<Any!>?): Int

Returns a hash code based on the "deep contents" of the specified array. If the array contains other arrays as elements, the hash code is based on their contents and so on, ad infinitum. It is therefore unacceptable to invoke this method on an array that contains itself as an element, either directly or indirectly through one or more levels of arrays. The behavior of such an invocation is undefined.

For any two arrays a and b such that Arrays.deepEquals(a, b), it is also the case that Arrays.deepHashCode(a) == Arrays.deepHashCode(b).

The computation of the value returned by this method is similar to that of the value returned by java.util.List#hashCode() on a list containing the same elements as a in the same order, with one difference: If an element e of a is itself an array, its hash code is computed not by calling e.hashCode(), but as by calling the appropriate overloading of Arrays.hashCode(e) if e is an array of a primitive type, or as by calling Arrays.deepHashCode(e) recursively if e is an array of a reference type. If a is null, this method returns 0.

Parameters
`a`	Array<Any!>?: the array whose deep-content-based hash code to compute

Return
`Int`	a deep-content-based hash code for `a`

#hashCode(Object[])

deepToString

Added in API level 1

static fun deepToString(a: Array<Any!>?): String

Returns a string representation of the "deep contents" of the specified array. If the array contains other arrays as elements, the string representation contains their contents and so on. This method is designed for converting multidimensional arrays to strings.

The string representation consists of a list of the array's elements, enclosed in square brackets ("[]"). Adjacent elements are separated by the characters ", " (a comma followed by a space). Elements are converted to strings as by String.valueOf(Object), unless they are themselves arrays.

If an element e is an array of a primitive type, it is converted to a string as by invoking the appropriate overloading of Arrays.toString(e). If an element e is an array of a reference type, it is converted to a string as by invoking this method recursively.

To avoid infinite recursion, if the specified array contains itself as an element, or contains an indirect reference to itself through one or more levels of arrays, the self-reference is converted to the string "[...]". For example, an array containing only a reference to itself would be rendered as "[[...]]".

This method returns "null" if the specified array is null.

Parameters
`a`	Array<Any!>?: the array whose string representation to return

Return
`String`	a string representation of `a`

Added in API level 1

static fun equals(
    a: FloatArray?, 
    a2: FloatArray?
): Boolean

Returns true if the two specified arrays of floats are equal to one another. Two arrays are considered equal if both arrays contain the same number of elements, and all corresponding pairs of elements in the two arrays are equal. In other words, two arrays are equal if they contain the same elements in the same order. Also, two array references are considered equal if both are null. Two floats f1 and f2 are considered equal if:

<code>Float.valueOf(f1).equals(Float.valueOf(f2))</code>

(Unlike the == operator, this method considers NaN equal to itself, and 0.0f unequal to -0.0f.)

Parameters
`a`	FloatArray?: one array to be tested for equality
`a2`	FloatArray?: the other array to be tested for equality

Return
`Boolean`	`true` if the two arrays are equal

The value returned by this method is the same value that would be obtained by invoking the java.util.List#hashCode() method on a List containing a sequence of Float instances representing the elements of a in the same order. If a is null, this method returns 0.

Parameters
`a`	FloatArray?: the array whose hash value to compute

Return
`Int`	a content-based hash code for `a`

hashCode

static fun hashCode(a: IntArray?): Int

Returns a hash code based on the contents of the specified array. For any two non-null int arrays a and b such that Arrays.equals(a, b), it is also the case that Arrays.hashCode(a) == Arrays.hashCode(b).

The value returned by this method is the same value that would be obtained by invoking the java.util.List#hashCode() method on a List containing a sequence of Integer instances representing the elements of a in the same order. If a is null, this method returns 0.

Parameters
`a`	IntArray?: the array whose hash value to compute

Return
`Int`	a content-based hash code for `a`

hashCode

static fun hashCode(a: Array<Any!>?): Int

Returns a hash code based on the contents of the specified array. If the array contains other arrays as elements, the hash code is based on their identities rather than their contents. It is therefore acceptable to invoke this method on an array that contains itself as an element, either directly or indirectly through one or more levels of arrays.

For any two arrays a and b such that Arrays.equals(a, b), it is also the case that Arrays.hashCode(a) == Arrays.hashCode(b).

The value returned by this method is equal to the value that would be returned by Arrays.asList(a).hashCode(), unless a is null, in which case 0 is returned.

Parameters
`a`	Array<Any!>?: the array whose content-based hash code to compute

Return
`Int`	a content-based hash code for `a`

static fun hashCode(a: LongArray?): Int

Returns a hash code based on the contents of the specified array. For any two long arrays a and b such that Arrays.equals(a, b), it is also the case that Arrays.hashCode(a) == Arrays.hashCode(b).

The value returned by this method is the same value that would be obtained by invoking the java.util.List#hashCode() method on a List containing a sequence of Long instances representing the elements of a in the same order. If a is null, this method returns 0.

Parameters
`a`	LongArray?: the array whose hash value to compute

Return
`Int`	a content-based hash code for `a`

static fun mismatch(
    a: BooleanArray, 
    b: BooleanArray
): Int

Finds and returns the index of the first mismatch between two boolean arrays, otherwise return -1 if no mismatch is found. The index will be in the range of 0 (inclusive) up to the length (inclusive) of the smaller array.

If the two arrays share a common prefix then the returned index is the length of the common prefix and it follows that there is a mismatch between the two elements at that index within the respective arrays. If one array is a proper prefix of the other then the returned index is the length of the smaller array and it follows that the index is only valid for the larger array. Otherwise, there is no mismatch.

Two non-null arrays, a and b, share a common prefix of length pl if the following expression is true:

<code>pl &gt;= 0 &amp;&amp;
      pl &lt; Math.min(a.length, b.length) &amp;&amp;
      Arrays.equals(a, 0, pl, b, 0, pl) &amp;&amp;
      a[pl] != b[pl]
  </code>

Note that a common prefix length of 0 indicates that the first elements from each array mismatch.

Two non-null arrays, a and b, share a proper prefix if the following expression is true:

<code>a.length != b.length &amp;&amp;
      Arrays.equals(a, 0, Math.min(a.length, b.length),
                    b, 0, Math.min(a.length, b.length))
  </code>

Parameters
`a`	BooleanArray: the first array to be tested for a mismatch
`b`	BooleanArray: the second array to be tested for a mismatch

Return
`Int`	the index of the first mismatch between the two arrays, otherwise `-1`.

Exceptions

static fun mismatch(
    a: IntArray, 
    b: IntArray
): Int

Finds and returns the index of the first mismatch between two int arrays, otherwise return -1 if no mismatch is found. The index will be in the range of 0 (inclusive) up to the length (inclusive) of the smaller array.

If the two arrays share a common prefix then the returned index is the length of the common prefix and it follows that there is a mismatch between the two elements at that index within the respective arrays. If one array is a proper prefix of the other then the returned index is the length of the smaller array and it follows that the index is only valid for the larger array. Otherwise, there is no mismatch.

static fun sort(a: Array<Any!>): Unit

Sorts the specified array of objects into ascending order, according to the natural ordering of its elements. All elements in the array must implement the Comparable interface. Furthermore, all elements in the array must be mutually comparable (that is, e1.compareTo(e2) must not throw a ClassCastException for any elements e1 and e2 in the array).

This sort is guaranteed to be stable: equal elements will not be reordered as a result of the sort.

Implementation note: This implementation is a stable, adaptive, iterative mergesort that requires far fewer than n lg(n) comparisons when the input array is partially sorted, while offering the performance of a traditional mergesort when the input array is randomly ordered. If the input array is nearly sorted, the implementation requires approximately n comparisons. Temporary storage requirements vary from a small constant for nearly sorted input arrays to n/2 object references for randomly ordered input arrays.

The implementation takes equal advantage of ascending and descending order in its input array, and can take advantage of ascending and descending order in different parts of the same input array. It is well-suited to merging two or more sorted arrays: simply concatenate the arrays and sort the resulting array.

The implementation was adapted from Tim Peters's list sort for Python ( TimSort). It uses techniques from Peter McIlroy's "Optimistic Sorting and Information Theoretic Complexity", in Proceedings of the Fourth Annual ACM-SIAM Symposium on Discrete Algorithms, pp 467-474, January 1993.

Parameters
`a`	Array<Any!>: the array to be sorted

Exceptions
`java.lang.ClassCastException`	if the array contains elements that are not mutually comparable (for example, strings and integers)
`java.lang.IllegalArgumentException`	(optional) if the natural ordering of the array elements is found to violate the `Comparable` contract

sort

Added in API level 1

static fun sort(
    a: ShortArray, 
    fromIndex: Int, 
    toIndex: Int
): Unit

Sorts the specified range of the array into ascending order. The range to be sorted extends from the index fromIndex, inclusive, to the index toIndex, exclusive. If fromIndex == toIndex, the range to be sorted is empty.

Parameters
`a`	ShortArray: the array to be sorted
`fromIndex`	Int: the index of the first element, inclusive, to be sorted
`toIndex`	Int: the index of the last element, exclusive, to be sorted

sort

Added in API level 1

static fun <T : Any!> sort(
    a: Array<T>, 
    fromIndex: Int, 
    toIndex: Int, 
    c: Comparator<in T>?
): Unit

Sorts the specified range of the specified array of objects according to the order induced by the specified comparator. The range to be sorted extends from index fromIndex, inclusive, to index toIndex, exclusive. (If fromIndex==toIndex, the range to be sorted is empty.) All elements in the range must be mutually comparable by the specified comparator (that is, c.compare(e1, e2) must not throw a ClassCastException for any elements e1 and e2 in the range).

This sort is guaranteed to be stable: equal elements will not be reordered as a result of the sort.

Implementation note: This implementation is a stable, adaptive, iterative mergesort that requires far fewer than n lg(n) comparisons when the input array is partially sorted, while offering the performance of a traditional mergesort when the input array is randomly ordered. If the input array is nearly sorted, the implementation requires approximately n comparisons. Temporary storage requirements vary from a small constant for nearly sorted input arrays to n/2 object references for randomly ordered input arrays.

The implementation takes equal advantage of ascending and descending order in its input array, and can take advantage of ascending and descending order in different parts of the same input array. It is well-suited to merging two or more sorted arrays: simply concatenate the arrays and sort the resulting array.

The implementation was adapted from Tim Peters's list sort for Python ( TimSort). It uses techniques from Peter McIlroy's "Optimistic Sorting and Information Theoretic Complexity", in Proceedings of the Fourth Annual ACM-SIAM Symposium on Discrete Algorithms, pp 467-474, January 1993.

Parameters
`<T>`	the class of the objects to be sorted
`a`	Array<T>: the array to be sorted
`fromIndex`	Int: the index of the first element (inclusive) to be sorted
`toIndex`	Int: the index of the last element (exclusive) to be sorted
`c`	Comparator<in T>?: the comparator to determine the order of the array. A `null` value indicates that the elements' natural ordering should be used.

Exceptions
`java.lang.ClassCastException`	if the array contains elements that are not mutually comparable using the specified comparator.
`java.lang.IllegalArgumentException`	if `fromIndex > toIndex` or (optional) if the comparator is found to violate the `Comparator` contract
`java.lang.ArrayIndexOutOfBoundsException`	if `fromIndex < 0` or `toIndex > a.length`
