Using JDK to implement a simple MD5 tool class in Java

MD5 Tool Class

Using the JDK to encapsulate a simple MD5 tool class, the logic is relatively simple, directly attached to the specific implementation

public static string GetMD5 (string content) {    string result = "";    try {        MessageDigest MD = messagedigest.getinstance ("MD5");        Md.update (Content.getbytes ());        byte[] bytes = Md.digest ();        StringBuilder sb = new StringBuilder ();        for (byte b:bytes) {            String str = integer.tohexstring (b & 0xFF);            if (str.length () = = 1) {                sb.append ("0");            }            Sb.append (str);        }        result = Sb.tostring ();    } catch (NoSuchAlgorithmException e) {        e.printstacktrace ();    }    return result;} @Testpublic void TestMd5 () {    System.out.println (getMD5 ("Hello World");}

The test output is:
