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;

boolean flag = true;
boolean ifstop = false;
public JFrame() {
