Java copy section of array

See the method Arrays.copyOfRange

Here's a java 1.4 compatible 1.5-liner:

int[] array = { 1, 2, 3, 4, 5 };
int size = 3;

int[] part = new int[size];
System.arraycopy(array, 0, part, 0, size);

You could do this in one line, but you wouldn't have a reference to the result.

To make a one-liner, you could refactor this into a method:

private static int[] partArray(int[] array, int size) {
    int[] part = new int[size];
    System.arraycopy(array, 0, part, 0, size);
    return part;
}

then call like this:

int[] part = partArray(array, 3);

int [] myArray = [1,2,3,4,5];

int [] holder = new int[size];

System.arraycopy(myArray,0,holder,size);

where 0 stands for the index of source array from where copying should start. and

size stands for the number of copy operations. That you can changes according to your need.

copyOfRange of Arrays is there and many other ways by which this can be accomplished
