If an exception occurs in the try block, the try block terminates. If the program catches the exception in one of the corresponding catch blocks, it processes the exception, then the finally block releases the resource and control proceeds to the first statement after the finally block. If the program doesn’t catch the exception, the finally block still releases the resource and an attempt ...
