How do I verify the data?

I've tried to output the sent data in String format in Java.
This is what I get:

public void Display_Msg(int SIZE){
       String S;
          int DisplayLen = 0;


          if (SIZE > txtSpd.getColumns()-1){

              for(int i = 0; i< txtSpd.getColumns(); i++){
                    //Convert converted arrayMsg to Hex in string (16 hexa), since Java's is 32Bits in byte
                   S = Integer.toString(ByteConversion(byteTxtMsg[i]), 16) + " ";
                   txtSpd.append(S);
               }
               txtSpd.append("\n");


               for(int j = txtSpd.getColumns()-1; j< SIZE; j++){
                //Convert converted arrayMsg to Hex in string (16 hexa), since Java's is 32Bits in byte

                   S = Integer.toString(ByteConversion(byteTxtMsg[j]), 16) + " ";
                   txtSpd.append(S);
                  DisplayLen = txtSpd.getLineCount();
                 }
                  txtSpd.append("\n");



               }




          if (SIZE <= txtSpd.getColumns()-1){


                   for(int i = 0; i< SIZE; i++){
                    //Convert converted int arrayMsg to Hex in string (16 hexa), since Java's is 32Bits in byte
                   S = Integer.toString(ByteConversion(byteTxtMsg[i]), 16) + " ";

                   txtSpd.append(S);
                   DisplayLen = txtSpd.getLineCount();
                }
                  txtSpd.append("\n");

           }




           if (DisplayLen > 18){
               txtSpd.setText("");
           }


            String dat1="";
             byte Msg[] = new byte[50];

           for (int k = 0; k<SIZE; k++){
             dat1 = Integer.toString(ByteConversion(byteTxtMsg[k]), 16) + " ";


           }

          Msg = dat1.getBytes();

          try{
            udpC.send(Msg);
          }

          catch (IOException w){
            System.out.println("Error: " + w);

           }

   }

public void send(byte[] data) throws IOException {

    if (data.length > 8192) throw new IOException("Too much data");
    
    DatagramPacket dp = new DatagramPacket(data, data.length, remote, port);
   
    ds.send(dp);
    

  }

Could it be that sending portion of the messages in bytes in Java has something to do with this, as it is known that the bytes in Java has some restrictions?

am I extracting chars from the array, in the correct manner?
