我正在尝试创建一个小程序，在某个时间间隔内点击鼠标左键。我无法解决的唯一问题是能够在我想要的时候停止循环，甚至在计时器用完之前。我发现一个人应该在一个工作线程中运行循环，并且我的停止按钮应该以某种方式中断该线程，但我无法管理它。我希望你能帮我一些代码。

相当一些代码是由netbeans生成的...... 我真的不知道如何制作一个新主题，而且我不知道如何制作我的文本字段（用于定时器）和我的按钮与线程进行通信......真的希望你能做到帮帮我：D
答案 0 :(得分：1)
you definitely want to look at timers. Basically, it's here to facilitate you the usage of threading. I didn't want to modify too much your code so I provide you a sample that replaces the do while loop you were using (it's from the official Timer's javadoc).
ActionListener taskPerformer = new ActionListener() {
public void actionPerformed(ActionEvent evt) {
do {
System.out.println("left click");
leftClick();
robot.delay(1500);
time_milli = time_milli - 1700;
} while (time_milli > 0);
}
};
new Timer(5000, taskPerformer).start();
Please note that I explicitely left the console print for you to check that you are called on action performed every 5 secondes ; also Timers keeps your GUI from being freezed when you click on the start button which is more user-friendly.

我非常感谢大家花时间给我提示。我现在已经解决了我的问题并将发布我的代码，以防其他人遇到类似的问题。每个部分都是一个单独的java类。计时器不是很准确，现在鼠标点击设置约2秒。代码可能不是很优雅，但至少它可以工作：D
简要概述：
按下开始按钮后，程序将等待5秒钟，然后每两秒执行一次鼠标左键单击，直到指定的持续时间过去或用户点击停止按钮。
