Thread: How to Use Timer in Java

Hi everybody i did a small sample about using Timers in Java it's so simple to use.The main idea that you want to execute simple process every specific time.

import java.util.Timer;
import java.util.TimerTask;
 
public class TimerSample {
 
    public static void main(String[] args) {
        //1- Taking an instance of Timer class.
        Timer timer = new Timer("Printer");
 
        //2- Taking an instance of class contains your repeated method.
        MyTask t = new MyTask();
 
 
        //TimerTask is a class implements Runnable interface so
        //You have to override run method with your certain code black
 
        //Second Parameter is the specified the Starting Time for your timer in
        //MilliSeconds or Date
 
        //Third Parameter is the specified the Period between consecutive
        //calling for the method.
 
        timer.schedule(t, 0, 2000);
 
 
    }
}
 
class MyTask extends TimerTask {
    //times member represent calling times.
    private int times = 0;
 
 
    public void run() {
        times++;
        if (times <= 5) {
            System.out.println("I'm alive...");
        } else {
            System.out.println("Timer stops now...");
 
            //Stop Timer.
            this.cancel();
        }
    }
}

Thank you for your useful post.

I run this program on netbeans. it worked well except that it didn't end on itself. so I added System.exit(0); after this.cancel();
