    Default try catch clarification

    I'm a bit confused about testing for exceptions. Does a try statement simply test? Or does it actually perform the code within it. For example
    if I have a statement such that:

    Java Code:
    boolean whatAmI = true;
           whatAmI = false
            throw new Exception();
    }catch(Exception e){
    System.out.println( e.getMessage());
    would WhatAmI remain true? would the message be printed (assuming no syntax errors)

    Default Re: try catch clarification

    Exception catching does not roll back actions that have already been done. In your example, whatAmI would be false after line 6. But, consider this: move the throw statement to line 3 (swap it with the assignment) and then what do you thing will happen?
