Returns a fixed-size list backed by the specified array.

  Returns a fixed-size list backed by the specified array. (Changes to the returned list "write through" to the array.) This method acts as bridge between array-based and collection-based APIs, in combination with Collection.toArray(). The returned list is serializable and implements RandomAccess.

This method also provides a convenient way to create a fixed-size list initialized to contain several elements:

     List<String> stooges = Arrays.asList("Larry", "Moe", "Curly");
 

Returns: a list view of the specified array
Parameters:
- a - the array by which the list will be backed

  Searches the specified array of bytes for the specified value using the binary search algorithm.

  Searches the specified array of bytes for the specified value using the
binary search algorithm. The array must be sorted (as
by the Arrays.sort(byte[]) method) prior to making this call. If it
is not sorted, the results are undefined. If the array contains
multiple elements with the specified value, there is no guarantee which
one will be found.
Returns: 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.
Parameters:
- a - the array to be searched
- key - the value to be searched for

  Searches a range of the specified array of bytes for the specified value using the binary search algorithm.

  Searches a range of

prior to making this call. If it
is not sorted, the results are undefined. If the range contains
multiple elements with the specified value, there is no guarantee which
one will be found.
Returns: 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.
Parameters:
- a - the array to be searched
- fromIndex - the index of the first element (inclusive) to be searched
- toIndex - the index of the last element (exclusive) to be searched
- key - the value to be searched for
Throws:
- IllegalArgumentException - if {@code fromIndex > toIndex}
- ArrayIndexOutOfBoundsException - if {@code fromIndex < 0 or toIndex > a.length}

  Returns true if the two specified arrays are deeply equal to one another.

  Returns true if the two specified arrays are deeply equal to one another. Unlike the Arrays.equals(Object[],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.
Returns: true if the two arrays are equal
Parameters:
- a1 - one array to be tested for equality
- a2 - the other array to be tested for equality
Since: 1.5
See Also: Arrays.equals(Object[],Object[]),

  Returns a hash code based on the "deep contents" of the specified array.

  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 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.
Returns: a deep-content-based hash code for a
Parameters:
- a - the array whose deep-content-based hash code to compute
Since: 1.5
See Also: Arrays.hashCode(Object[]),

  Returns a string representation of the "deep contents" of the specified array.

  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.
Returns: a string representation of a
Parameters:
- a - the array whose string representation to return

Parameters:
- a - the array whose hash value to compute
Since: 1.5

  Returns a hash code based on the contents of the specified array.

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.

  Sorts the specified array of doubles into ascending numerical order.

  Sorts the specified array of doubles into ascending numerical order.

The < relation does not provide a total order on all floating-point values; although they are distinct numbers -0.0 == 0.0 is true and a NaN value compares neither less than, greater than, nor equal to any floating-point value, even itself. To allow the sort to proceed, instead of using the < relation to determine ascending numerical order, this method uses the total order imposed by Double.compareTo(java.lang.Double). This ordering differs from the < relation in that -0.0 is treated as less than 0.0 and NaN is considered greater than any other floating-point value. For the purposes of sorting, all NaN values are considered equivalent and equal.

  Sorts the specified array of floats into ascending numerical order.

The < relation does not provide a total order on all floating-point values; although they are distinct numbers -0.0f == 0.0f is true and a NaN value compares neither less than, greater than, nor equal to any floating-point value, even itself. To allow the sort to proceed, instead of using the < relation to determine ascending numerical order, this method uses the total order imposed by Float.compareTo(java.lang.Float).
