Write a small program yourself, compile it and run it to find out what happens. The best way to learn is to experiment.

If you will get an exception it will go to the catch and finally and if no exception then only finally.So return will not effect much.
Best way is write a code and run all aspects,the questions in your mind.

Hi,
Here's the thing that you should burn in when it comes to TRY and CATCH.

1. No matter whether an exception is thrown or not, finally block will be executed!!!.

2. If an exception is thrown, return will not be executed, catch and then finally both will be executed.

I believe that the only way to prevent a finally-block from being executed is to call the method:

System.exit();

The fact that this prevents finally from being called may be a reason to throw an exception or an error instead of calling System.exit();

It is sorta covered in the JavaRanch Style Guide.
