How to check if one of the thread has failed?

I have a multi-threaded Java application. I want the whole application to fail is one of the thread encounters any exception.

I don't think doing System.exit(); inside the thread will exit the whole app.

Can someone suggest a way?

put try-catch in Thread's run method and in catch block System.exit(0); it works.

actually, calling System.exit() will exit the whole app, but that's generally not what you want in your library code (for instance, it makes unit testing difficult).

a better implementation is to have a shared "error handler" reference, with an implementation that you control. in unit tests, you could just log the exception. in your real app, you could call System.exit().

One simple way to do that is to have try{} catch{} on each thread, when you catch exception you may call static function that exits the application.
