### Question:
TypeConversion { public static String bytesToHexString(byte[] src) { return Hex.encodeHexString(src); }  static byte[] longToBytes(long x); static long bytesToLong(byte[] bytes); static String bytesToHexString(byte[] src); static byte[] hexStringToBytes(String hexString); static boolean increment(byte[] bytes);  }### Answer:
@Test public void testBytesToHexString() { String result = bytesToHexString(new byte[]{0, 0, 0, 0, 0, 0, 0, 125}); assertEquals("000000000000007d", result); }
