推荐答案p>您可以通过执行以下操作为应用程序添加一个关闭钩子:
You can add a shutdown hook to your application by doing the following:
Runtime.getRuntime().addShutdownHook(new Thread(new Runnable() { public void run() { // what you want to do } }));这基本上等同于在整个程序中尝试{} finally {}包含最后的块中的内容。
This is basically equivalent to having a try {} finally {} block around your entire program, and basically encompasses what's in the finally block.
请注意注意事项!
