Remarks

Generates random bytes and places them into a user-supplied byte array. The number of random bytes produced is equal to the length of the byte array.

The method nextBytes is implemented by class Random as if by:

{@code
            public void nextBytes(byte[] bytes) {
              for (int i = 0; i < bytes.length; )
                for (int rnd = nextInt(), n = Math.min(bytes.length - i, 4);
                     n-- > 0; rnd >>= 8)
                  bytes[i++] = (byte)rnd;
            }}
