How to configure a java timer event listener

To add a listener event for a Java timer, you can use the javax.swing.Timer class. Below is a simple example code that demonstrates how to set up the timer and add a listener event:

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

public class TimerExample {

    public static void main(String[] args) {
        int delay = 1000; // 1 second
        Timer timer = new Timer(delay, new ActionListener() {
            @Override
            public void actionPerformed(ActionEvent e) {
                // 执行定时任务的代码
                System.out.println("Timer fired!");
            }
        });

        timer.start();
    }
}

In the code above, a Timer object is created with a delay of 1 second and an ActionListener event listener is added. In the actionPerformed method, you can write the code for the timed task. Finally, call timer.start() method to start the timer.

The code for the delay time and scheduled task can be modified based on the requirements to achieve different functionalities.
