byte[]convertToByteArray(long l)
Converts the long to a 4 byte array. 
byte[] b = new byte[4];
b[0] = (byte) (255 & (l >> 24));
b[1] = (byte) (255 & (l >> 16));
b[2] = (byte) (255 & (l >> 8));
b[3] = (byte) (255 & l);
return b;

byte[] b = new byte[8];
for (int i = 0; i < 8; i++) {
    b[i] = (byte) (num >>> (56 - i * 8));
return b;
byte[]toBytes(long longValue)
to Bytes 
return new byte[] { (byte) (longValue >>> 56),
