public void swap(int[] a, int[] b) { int temp = a[0]; a[0] = b[0]; b[0] = temp; }
Unfortunately, code that uses this swap method must know to package their variables into one element arrays before calling swap.
For example:
int[] x = new int[1]; int[] y = new int[1]; x[0] = 20; y[0] = 15; swap(x, y);
