How to make Java program exit after a couple of seconds

Is there anyway I can exit a java program after a couple of seconds e.g. 5 seconds.

I know you can quit the java program using:

System.exit(0);

But I'm not sure whether the 0 stands for seconds since this code:

System.exit(10);

also exits instantly

Solution

  • System.exit(0) specifies the exit error code of the program.

    you can put it on a timer and schedule the task 

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

public class TimedExit {
Timer timer = new Timer();
TimerTask exitApp = new TimerTask() {
public void run() {
    System.exit(0);
    }
};

public TimedExit() {
timer.schedule(exitApp, new Date(System.currentTimeMillis()+5*1000));
    }

}

    and then you can just called TimedExit()
