### Question:
Md5Util { public static String getMd5(String value) { try { MessageDigest md5 = MessageDigest.getInstance("MD5"); byte[] bytes = md5.digest(value.getBytes(StandardCharsets.UTF_8)); return bytes2Hex(bytes); } catch (Exception e) { throw new RuntimeException("Get md5 error:", e); } }  static String getMd5(String value);  }### Answer:
@Test public void testGetMd5() { String result = Md5Util.getMd5("123456"); Assert.assertEquals(result, "e10adc3949ba59abbe56e057f20f883e"); }
