MD5.getHashString or routines code source for Hash Value

[ZZoghlemi1703518476]

i have this routines for hash value but did'nt work , someone have other solution please

routines.Hashage_Fonction.calculateMD5(row1.NUMCNT+row1.CODFAM+row1.CODPROD+row1.FORMCNT+row1.NATCLT+row1.IDCLT+row1.SITUAT ) ---> inp_hash

routines.Hashage_Fonction.calculateMD5(row2.NUMCNT+row2.CODFAM+row2.CODPROD+row2.FORMCNT+row2.NATCLT+row2.IDCLT+row2.SITUAT) ---> kp_hash

(!Var.inp_hash.equals(Var.kp_hash))?"updpted":"ot_updated" 

package routines;

//Import necessary libraries

import java.security.MessageDigest;

import java.security.NoSuchAlgorithmException;

import java.nio.charset.StandardCharsets;

import org.apache.commons.codec.binary.Hex;

import java.security.MessageDigest;

import java.security.NoSuchAlgorithmException;

public class Hashage_Fonction {

  public static String calculateMD5(String input) {

    try {

      MessageDigest md = MessageDigest.getInstance("MD5");

      md.update(input.getBytes());

      byte[] digest = md.digest();

      StringBuilder hexString = new StringBuilder();

      for (byte b : digest) {

        hexString.append(String.format("%02x", b));

      }

      return hexString.toString();

    } catch (NoSuchAlgorithmException e) {

      e.printStackTrace();

      return null;

    }

  }

}

please any help

thanks
