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);
