The finally block always executes, even if exceptions are not there. So, if you forget to write a requisite try or you want your program to end in a specified way, finally comes to play.

The finally block will execute whether or not an exception is thrown. If an exception is thrown, the finally block will execute even if no catch statement matches the exception.

If you can't handle them locally then just having a try / finally block...
