Java – defines a global uncaughtexceptionhandler for all threads of the application

I want to define an application level uncaughtexceptionhandler in my java application. If an uncaught exception is thrown in a thread of my application, it will be called

So for example, I want something like this:

1° LEVEL ---> Call thread own UncaughtExceptionHandler ---> 2° LEVEL Call Thread Group UncaughtExceptionHandler ---> 3° LEVEL Call application(default) UncaughtExceptionHandler

Simply put, I want to override the default uncaughtexceptionhandler and define my own handler, not in system Print stack trace on err (this is the default behavior)

For example, in C # Net, I will execute the unhandled and thread exception event handling functions in the main () method of the processing application:

AppDomain.CurrentDomain.UnhandledException += new UnhandledExceptionEventHandler(CurrentDomain_UnhandledException); 
Application.ThreadException += new System.Threading.ThreadExceptionEventHandler(Application_ThreadException);

Can it even be done in Java?

How do I override the default uncaughtexceptionhandler in Java?

Solution

Thread. setDefaultUncaughtExceptionHandler(UncaughtExceptionHandler ex)

This should achieve what you are looking for

As the document says

And an interesting comment (also in the documentation) about your use of handlers in ThreadGroup
