Running code on program exit in Java

问题

Is it possible to write a method that System.exit will call when you terminate a program?

回答1:

Use Runtime.getRuntime().addShutdownHook(Thread).

回答2:

Shutdown hooks are the answer... here is an article on them. They do not come without issues (some of them are discussed in the article).

回答3:

You can use a shutdown hook.

Note that shutdown hooks will not run if the VM aborts abnormally or Runtime.halt(int) is called.
