You want to use a Swing Timer object. Here is a Oracle tutorial

To start with, you need to have your class implement the ActionListener interface. Inside of your class, you also need to implement an actionPerformed() method. Finally, you should start the timer in your main() function or somewhere

timer = new Timer(5000, MyClass);
timer.setInitialDelay(pause);
timer.start();

public class MyClass implements ActionListener

       */
   }
