    The javax.swing.Timer class in Java is used to fire one or more ActionEvents at specified intervals. This is particularly useful for creating animations or performing periodic tasks in a Swing application. The Timer class is part of the Swing framework and is designed to work seamlessly with the event-dispatching thread, ensuring that the GUI remains responsive.

    Creating and Using a Timer

    To set up a timer, you need to create a Timer object, register one or more action listeners on it, and start the timer using the start method. Here is an example of how to create and start a timer that fires an action event once per second:

    import javax.swing.Timer;
    import java.awt.event.ActionEvent;
    import java.awt.event.ActionListener;

    public class TimerExample {
    public static void main(String[] args) {
    int delay = 1000; // milliseconds
    ActionListener taskPerformer = new ActionListener() {
    public void actionPerformed(ActionEvent evt) {
    // Perform a task
    System.out.println("Timer event fired!");
    }
    };
    new Timer(delay, taskPerformer).start();
    }
    }
    Copied!
    Why does Java Swing timer stop working?
    Unhandled exceptions can cause the timer to stop working. If you no longer need the timer, make sure to stop it and release any associated resources to avoid memory leaks. The Java Swing Timer is a powerful and versatile tool for performing tasks at specified intervals in Java GUI applications.

      Java Swing Timer - Stack Overflow

      I think I'm right in saying the java.swing.Timer is intended for UI related timed operations, hence why it needs and EDT running. For more general operations you should use java.util.Timer.

      Code sample

      Timer timer = new Timer(100 ,taskPerformer);
      timer.setRepeats(false);
      timer.start();
