如 Java API文档用于 javax.swing.Timer 显示：

int delay = 5000; //milliseconds
ActionListener taskPerformer = new ActionListener() {
    public void actionPerformed(ActionEvent evt) {
        //...Perform a task...
    }
};
Timer timer = new Timer(delay, taskPerformer);
timer.setRepeats(false);
timer.start();

提示：如果不确定某些功能，请使用Java API文档。它为您省去了很多麻烦。

Hint: Use the Java API docs if you're unsure how something works. It saves you a lot of trouble.
