frame vs. JFrame

[Abder Rahman Ali]

Is there a difference between using frame or JFrame as in the following? As, when I ran the program it operated the same.

    
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

    
frame.setDefaultCloseOperation(frame.EXIT_ON_CLOSE);

Thanks.

... in the behavior of your program there shouldn't be a difference as you stated already.
But it would be interesting to see, if byte code differs?
I guess it doesn't, because sun's compiler should recognize that this is a final static field, i.e. a constant.

But anyway, even this doesn't probably relate to your question,
most IDE's would issue a warning if you use latter code
and sun also highly recommends to use the first statement instead.

Since his "frame" is not capitalized, I'm guessing that the OP is not mixing Frame (AWT) with Swing but rather that he has a JFrame variable named "frame" and is asking if calling a static method or referencing a static variable from an object of the class will change his code.

To the OP: as noted above, it likely won't but it will sure confuse folks reading your code since most of us expect static members to be referenced by the class name not by a variable of the class that holds an object of the class. Since much of coding is not writing for a compiler but rather writing for readability, I agree with others who tell you "don't do this".
