Is there an equivalent to memcpy() in Java?

Question

I have a byte[] and would like to copy it into another byte[]. Maybe I am showing my simple \'C\' background here, but is there an equivalent to memcpy() on byte arrays in

Answer 1

If you just want an exact copy of a one-dimensional array, use clone().

byte[] array = { 0x0A, 0x01 };
byte[] copy = array.clone();

For other array copy operations, use System.arrayCopy/Arrays.copyOf as Tom suggests.

In general, clone should be avoided, but this is an exception to the rule.
