I just wrote this code to turn a GUID into a byte array. Can anyone shoot any holes in it or suggest something better?
public static byte[] getGuidAsByteArray(){
UUID uuid = UUID.randomUUID();
long longOne = uuid.getMostSignificantBits();
long longTwo = uuid.getLeastSignificantBits();
return new byte[] {
(byte)(longOne >>> 56),
(byte)(longOne >>> 48),
(byte)(longOne >>> 40),
(byte)(longOne >>> 32),
(byte)(longOne >>> 24),
(byte)(longOne >>> 16),
(byte)(longOne >>> 8),
(byte) longOne,
(byte)(longTwo >>> 56),
(byte)(longTwo >>> 48),
(byte)(longTwo >>> 40),
(byte)(longTwo >>> 32),
(byte)(longTwo >>> 24),
(byte)(longTwo >>> 16),
(byte)(longTwo >>> 8),
(byte) longTwo
};
}
