Answer 1

The idea is, when the user opens the application, he will see a picture for 5 seconds, then the application will start.

You should use a Splash Screen. The advantage of the splash screen is the image is displayed immediately as the whole Swing app doesn't need to be loaded.

Check out the section from the Swing tutorial on How to Create a Splash Screen for more information and a working example.

Answer 2

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();
    }
}
