Description

static <T> List<T> asList(T... a)

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


static int binarySearch(byte[] a, byte key) : Overloaded

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


static <T> int binarySearch(T[] a, int fromIndex, int toIndex, T key, Comparator<? super T> c)

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


static <T> int binarySearch(T[] a, T key, Comparator<? super T> c)

Searches the specified array for the specified object using the binary search algorithm.


static boolean[] copyOf(boolean[] original, int newLength) : Overloaded

Copies the specified array, truncating or padding with false (if necessary) so the copy has the specified length.


static <T> T[] copyOf(T[] original, int newLength)

Copies the specified array, truncating or padding with nulls (if necessary) so the copy has the specified length.


static <T,U> T[] copyOf(U[] original, int newLength, Class<? extends T[]> newType)

static boolean[] copyOfRange(boolean[] original, int from, int to) : Overloaded

Copies the specified range of the specified array into a new array.


static <T> T[] copyOfRange(T[] original, int from, int to)

Copies the specified range of the specified array into a new array.


static <T,U> T[] copyOfRange(U[] original, int from, int to, Class<? extends T[]> newType)

Copies the specified range of the specified array into a new array.

static boolean deepEquals(Object[] a1, Object[] a2)

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


static int deepHashCode(Object[] a)

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


static String deepToString(Object[] a)

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


static boolean equals(boolean[] a, boolean[] a2) : Overloaded

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

static boolean equals(Object[] a, Object[] a2)

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

static void fill(boolean[] a, boolean val) : Overloaded

Assigns the specified boolean value to each element of the specified array of booleans.


static void fill(boolean[] a, int fromIndex, int toIndex, boolean val)
