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()
