Is there such case when in try\finally block the finally won't be executed?

I'm relatively new to java and I've just heard about try-catch blocks (3 minutes ago to be exact).

In a try-catch block, is the finally part (when present) ever not executed?

try {
    if (choice) {
        //...
    } else {
        //...
    }
} finally {
    doesThisEverNOTrun();
}

Yes.

try {
    if (choice) {
        while (true);
    } else {
        System.exit(0);
    }
} finally {
    doesThisEverNotRun(YES);
}

More often than not, though, the finally part is executed.

_"More often than not"_. Gee, that sure is a useful statement. `` – Matt Ball Aug 20 '11 at 13:39
@Matt Ball It actually *is* useful when you think about it :) – fireshadow52 Aug 20 '11 at 13:40
@Tony No problem! That's why we're here. :) – fireshadow52 Aug 20 '11 at 13:45
actually a try must have a `finally` OR a `catch` i.e. when there is a finally a catch is not mandatory – ratchet freak Aug 20 '11 at 13:46
@ratchet freak LOL forgot about that. I'll change my answer. :) – fireshadow52 Aug 20 '11 at 13:50

If the (virtual) machine does not crash, you don't call System.exit() in the try or a catch block, the finally block will execute.
