There is a global exception handling in JVM layer.

EDIT.

You can implement global exception handling using Thread.setDefaultUncaughtExceptionHandler()

According to the Java API documentation, when a thread is going to terminate due to an uncaught exception, the Java Virtual Machine will query the thread for its UncaughtExceptionHandler

As our program has main Thread JVM ask main about Exception Handler by Thread.getUncaughtExceptionHandler().

Than invokes handler by passing Thread and Exception as an argument to handle Exception
