Is there any reason to prefer System.arraycopy() over clone()?

Question

When copying an entire array, I\'ve often seen people write:

int[] dest = new int[orig.length];
System.arraycopy(orig, 0, dest, 0, orig.length);

Answer 1

No. If you're really microbenchmarking, then maybe, depending on what JVM you're running. But in actuality, no.
