Question

try {
    if (check) {
        while (true) ;
    } else {
        System.exit(1);
    }
} finally {
    clear();
}

Q: Is there a case where clear() never gets executed?
I personally feel that there are no cases where clear() will not be executed.

Answer 1

System.exit(1) prevents the finally clause from running.

Basically a finally block is executed after a try/catch regardless if the try or the catch returned normally or exceptionally.

A System.exit however prevents the block from returning at all.

while(true) ; will obviously block indefinitely. just assumed that the while (true) ; was a stub for something that made more sense 🙂
