Method Detail

copyOf

public static final <E> E[] copyOf(E[] source,
                                   int len)

Arrays.copyOf(...) is a Java6 thing. This is a replacement.

Type Parameters:

E - The generic type of the array we are copying.

Parameters:

source - the source array.

len - the length of the new array copy.

Returns:

a new array that has the same elements as the source.

copyOfRange

public static final <E> E[] copyOfRange(E[] source,
                                        int from,
                                        int to)

Arrays.copyOf(...) is a Java6 thing. This is a replacement.

Type Parameters:

E - The generic type of the array we are copying.

Parameters:

source - the source array.

from - the start point of the copy (inclusive).

to - the end point of the copy (exclusive).

Returns:

a new array that has the same elements as the source.

copyOf

public static final char[] copyOf(char[] source,
                                  int len)

Arrays.copyOf(...) is a Java6 thing. This is a replacement.

Parameters:

source - the source array.

len - the length of the new array copy.

Returns:

a new array that has the same elements as the source.

copyOf

public static final int[] copyOf(int[] source,
                                 int len)

Arrays.copyOf(...) is a Java6 thing. This is a replacement.

Parameters:

source - the source array.

len - the length of the new array copy.

Returns:

a new array that has the same elements as the source.

copyOf

public static final boolean[] copyOf(boolean[] source,
                                     int len)

Arrays.copyOf(...) is a Java6 thing. This is a replacement.

Parameters:

source - the source array.

len - the length of the new array copy.

Returns:

a new array that has the same elements as the source.
