I'm sure this question has been asked before on here, but after searching around google and here I couldn't find anything.
Here's my situation, I've got multiple threads writing to a file, and a main thread that creates a print writer and handles creating the file and closing the print writer inside a finally block in a try/catch loop. When I run the application inside eclipse, I would press the stop/terminate button, and the file doesn't have anything written to it. I want to ensure that I'm doing everything correct here, or if there's a better way to handle closing a print writer whenever execution is terminated. Heck, if there's a better way to handle multiple threads writing to a file, I'm welcome to that advice (I'm pretty terrible at multithreaded programming right now).
There is only rare fact that finally isn't executed.
One of if can be: System.exit(0).
Using finally assumes that the statement in finally blocks is always executed.
Due to your problem make sure that your thread haven't executed already your finally block: make sure you use synchronization if it is needed - check it always with the unit-test.
