Java Question Problem 😮

Question

What will happen if we put System.exit(0) on try or catch body? Will finally block executed or any new exception will generate????

Answer 1

@Nithiwat that means when we call system.exit() method in try catch body then finally block will not execute 😮 btw one of my friend is saying that if we call system.exit() which is written in try or catch block then then a new exception will generate and because of that finally block will executed

Answer 2

The only times finally won't be called are:

1. If you invoke System.exit();
2. If the JVM crashes first;
3. If there is an infinite loop (or some other non-interruptable, non-terminating statement) in the try block;
4. If the OS forcibly terminates the JVM process; e.g. "kill -9 " on UNIX.
5. If the host system dies; e.g. power failure, hardware error, OS panic, etcetera.
