Using a Timer in Swing to display a picture for 5 seconds

Answer 1

Start by creating the Timer once in the constructor. The Timer should, also, only make the CURRENT instance of login close

public login() {
    //...
    time = new Timer(5000,new ActionListener() {
         @Override
         public void actionPerformed(ActionEvent e) {
              dispose();
         }
     });
     timer.setRepeats(false);
}

In the shoutoff method, you start timer...

public void shoutoff(){
    if (!time.isRunning()) {
        timer.start();
    }
}
