voidrandomize(byte[] array)
Fills an array with random values. 
Random rnd = new Random(System.currentTimeMillis());
int len = array.length;
int count = (len / 8);
int rest = (len - (count * 8));
int index = 0;
for (index = 0; index < count; index += 8) {
    longAsLittleEnd(array, index, rnd.nextLong());
if (rest >= 4) {
    intAsLittleEnd(array, index, rnd.nextInt());
    index += 4;
    rest -= 4;
if (rest >= 2) {
    shortAsLittleEnd(array, index,
            (short) (rnd.nextInt() & 0x0000FFFF));
    index += 2;
    rest -= 2;
if (rest >= 1) {
