### Question:
Utils { public static UUID uuidFromInteger(int value) { final long msb = 0x0000000000001000L; final long lsb = 0x800000805f9b34fbL; long v = value & 0xFFFFFFFF; return new UUID(msb | (v << 32), lsb); } private  Utils(); static String bytesToHex(byte[] bytes); static UUID uuidFromInteger(int value);  }### Answer:
@Test public void uuidFromInteger() { assertEquals( UUID.fromString("c7971000-0000-1000-8000-00805f9b34fb"), Utils.uuidFromInteger(0xC7971000)); }
