Hello everyone,

I have some problems with my program , hope you can help me to solve it.

1- I need a method for the Clear Time button that remove the counter to be 0.

` private void btclearActionPerformed(java.awt.event.ActionEvent evt) {                          
   // TODO add your handling code here:
       min=0;sec=0;

          lblsec.remove(lblsec);
          lblsec.setText("00");
           sec = Integer.parseInt(lblsec.getText());
          lblmin.setText("00");
          min = Integer.parseInt(lblmin.getText());

}    `

2- When i press the start button, the counter starts , After that i press the stop button and i want to add more time to the counter, but when i press the start button the counter starts with the old time not in new added time.

this is my code:

import java.awt.Color;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import javax.swing.JOptionPane;
import javax.swing.Timer;

public class JFrame extends javax.swing.JFrame {

   int sec,min,min1,sec1;
   Timer timer;
   boolean flag = true;
   boolean ifstop = false;

    public JFrame() {
        initComponents();
    }
     public void start(){
        bt10s.setEnabled(false);
         bt20s.setEnabled(false);
          bt30s.setEnabled(false);
           bt1m.setEnabled(false);
            bt5m.setEnabled(false);
             bt10m.setEnabled(false);
              btclear.setEnabled(false);
              btOpenDoor.setEnabled(false);

     }

     public void stop(){
         bt10s.setEnabled(true);
         bt20s.setEnabled(true);
          bt30s.setEnabled(true);
           bt1m.setEnabled(true);
            bt5m.setEnabled(true);
             bt10m.setEnabled(true);
              btclear.setEnabled(true);
              btOpenDoor.setEnabled(true);
              btCloseDoor.setEnabled(true);
