Finally

The finally clause is generally used to clean up after the code in the try clause (e.g., close files and shut down network connections). The finally clause is useful because it is guaranteed to be executed if any portion of the try block is executed, regardless of how the code in the try block completes. In fact, the only way a try clause can exit without allowing the finally clause to be executed is by invoking the System.exit() method, which causes the Java interpreter to stop running.

In the normal case, control reaches the end of the try block and then proceeds to the finally block, which performs any necessary cleanup. If control leaves the try block because of a return, continue, or break statement, the finally block is executed before control transfers to its new destination.

If an exception occurs in the try block and there is an associated catch block to handle the exception, control transfers first to the catch block and then to the finally block. If there is
