Java Swing 计时器 [英] Java Swing Timer

问题描述

ActionListener taskPerformer = new ActionListener() {
    public void actionPerformed(ActionEvent evt) {
        //...Perform a task...

        logger.finest("Reading SMTP Info.");
    }
};
Timer timer = new Timer(100 ,taskPerformer);
timer.setRepeats(false);
timer.start();

根据文档，这个计时器应该触发一次，但它永远不会触发.我需要它触发一次.

According to the documentation this timer should fire once but it never fires. I need it to fire once.

推荐答案

这个简单的程序对我有用:

This simple program works for me:

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

public class Test {
    public static void main(String [] args) throws Exception{
        ActionListener taskPerformer = new ActionListener() {
            public void actionPerformed(ActionEvent evt) {
                //...Perform a task...

                System.out.println("Reading SMTP Info.");
            }
        };
        Timer timer = new Timer(100 ,taskPerformer);
        timer.setRepeats(false);
        timer.start();

        Thread.sleep(5000);
    }
}
