控制 - Java 中的 C 异常
我需要捕获该异常，但我不知道它是哪一个。我现在使用的 IDE 不允许这样的程序中断。
我知道如何使用 try/catch，但我实际上不知道我要捕获什么。
任何人都可以帮助我吗？
I need to catch that exception but I can't figure out which one it is. The IDE i'm using right now doesn't allow for a program interrupt that way.
I know how to user try/catch, but I don't actually know what I'm trying to catch..
Can anyone help me with this?

我似乎记得 CTRL-C 变成了 InterruptedException 并且这篇 文章似乎支持这一点。正如其他答案中所建议的，使用
addShutdownHook是一个好方法，除非您想阻止关闭。I seem to recall that CTRL-C becomes an InterruptedException and this article seems to support that. As suggested in other answers the use of
addShutdownHookis a good way to go, unless you want to prevent the shutdown.听起来你需要
Runtime.addShutdownHook()我不确定您是否真的可以捕获它，您只需提供一个在虚拟机关闭时运行的
Thread即可。我认为一旦开始你就无法阻止它。Sounds like you need
Runtime.addShutdownHook()I'm not sure if you can actually catch it as such, you just supply a
Threadto be run when the VM is shutting down. I don't think you can stop it once this kicks off.addShutdownHook() 就是你想要的。

addShutdownHook() is what you want.
