235 views Asked by At

Hi I have been struggling the last few days and can't seem to solve the problem I want to make a timer in a Jframe that will be reset and start again. I seem to get error the the timer has been canceled but can't how to solve this , any help will be appreciated. Here is my code

package cubebuddy;

import java.util.Timer;
import java.util.TimerTask;

public class One_timer extends javax.swing.JFrame {

    Timer timer= new Timer();
    String ms, s, m;

    public One_timer() {
        initComponents();
    }
     TimerTask  myTimerTask = new TimerTask() {            
        @Override
            public void run() {               
                ms = Timer_display_ms.getText();
                s = Timer_display_s.getText();
                m = Timer_display_m.getText();
                Long MS_timer = Long.valueOf(ms);
                Long S_timer = Long.valueOf(s);
                Long M_timer = Long.valueOf(m);
                if (ms.equals(Long.toString(99))) {
                    s = Long.toString(++S_timer);
                    Timer_display_s.setText(s);
                }
                if ("99".equals(Timer_display_ms.getText())) {
                    Timer_display_ms.setText("0");
                } else {
                    ms = Long.toString(++MS_timer);
                    Timer_display_ms.setText(ms);
                }
                if (s.equals(Long.toString(60))) {
                    m = Long.toString(++M_timer);
                    Timer_display_m.setText(m);

Not the most elegant solution but you could covert your timer task to a nested class and create a new timer and task each time you start the watch. I think ScheduledExecutorService is general easier to use than the Timers so you might take a look at it.

private void OT_start_buttonActionPerformed(java.awt.event.ActionEvent evt) {
    // TODO add your handling code here:
    timer = new Timer();
    MyTimerTask task = new MyTimerTask();
    timer.schedule(task, 0, 1);
}


private class MyTimerTask extends TimerTask {
    @Override
    public void run() {
        ms = Timer_display_ms.getText();
        s = Timer_display_s.getText();
        m = Timer_display_m.getText();
        Long MS_timer = Long.valueOf(ms);
        Long S_timer = Long.valueOf(s);
        Long M_timer = Long.valueOf(m);
        if (ms.equals(Long.toString(99))) {
            s = Long.toString(++S_timer);
            Timer_display_s.setText(s);
        }
        if ("99".equals(Timer_display_ms.getText())) {
            Timer_display_ms.setText("0");
        } else {
            ms = Long.toString(++MS_timer);
            Timer_display_ms.setText(ms);
        }
        if (s.equals(Long.toString(60))) {
            m = Long.toString(++M_timer);
            Timer_display_m.setText(m);
            Timer_display_s.setText("0");
        }
    }

};
