Convert String to MD5 string via BigInteger

Demo Code

import java.math.BigInteger;
import java.security.MessageDigest;
import java.security.NoSuchAlgorithmException;

public class Main{

    public static String md5(String s) {

        MessageDigest m = null;//from  w  w w.j ava 2  s  . c  o m

        try {
            m = MessageDigest.getInstance("MD5");
        } catch (NoSuchAlgorithmException e) {
            throw new RuntimeException(e);
        }

        m.update(s.getBytes());

        String hash = new BigInteger(1, m.digest()).toString(16);

        return hash;
    }
    public static String md5(long l) {
        return md5(Long.toString(l));
    }
    public static String md5(int i) {
        return md5(Integer.toString(i));
    }

}
