就是让JAVA每个一段时间自动中断一次，执行一个函数的方法？

public final static int ONE_SECOND = 1000;
...
timer = new Timer(ONE_SECOND, new ActionListener() {
    public void actionPerformed(ActionEvent evt) {
//...Perform a task...
    }
});

//start the timer:
timer.start();

When the task is finished, the timer's action listener stops the timer:
if (/* task is done */) {
    ...
    timer.stop();
    ...
}
