Stopping Java timer

Question

new Timer(1000, new ActionListener() {
 @Override
 public void actionPerformed(ActionEvent e) {
 timeout--;
 if(timeout>=1){
 status1.setText("Time out: " + timeout);
 }else{
 patient1.setText("Patient: ");
 status1.setText("Status: Available");
 doctor.get(0).setStatus(true);
 countDoc++;
 setDoc.setText(avDoc + countDoc);
 timeout = 24;
 }
 }
}).start();

How to stop this piece of timer at the end of the else statement? I really scratched my head for this and searched almost everywhere

Answer 1

If you're trying to stop the Timer from within its ActionListener, then you can get the reference to the Timer object from the ActionEvent's getSource() method, and then stop it by calling stop() on the reference:

((timer) e.getSource()).stop();

or to break it down:

// assuming an ActionEvent variable named e
Timer timer = (Timer) e.getSource();
timer.stop();

and in context:

public void actionPerformed(ActionEvent e) {
 timeout--;
 if(timeout>=1){
 status1.setText("Time out: " + timeout);
 }else{
 patient1.setText("Patient: ");
 status1.setText("Status: Available");
 doctor.get(0).setStatus(true);
 countDoc++;
 setDoc.setText(avDoc + countDoc);
 timeout = 24;
 ((timer) e.getSource()).stop();
 }
}

• Leon: I got it working now but another question. Timer timer = (Timer) e.getSource(); What does the Timer in bracket does?
• Hovercraft Full Of Eels: @user3083413: I'm glad that you've got it working. What do you mean by "bracket"? Do you mean the (Timer) statement? That's a cast which is required since getSource() is declared to return Object.
• Leon: Understood fully now. Thanks sir

Answer 2

define the timer first as in:

Timer tim = new Timer(......)
tim.start();
tim.stop();

this will allow you yo stop the timer anywhere (providing you make it global)

you can also change it's attributes easily if you tie it to a var rather than creating an object like that..
