    Default Printing Using Swing.

    I have my GUI All made, and this is my code below, I know this is what I have to use to output the area in my GUI, but does it go seperately after each if statement or at the end of them all?
    String strArea = String.valueOf(area); 
            outputLabel.setText(strArea + " square inches");

    Can you clarify your question a bit? Please assume that we have no idea what this program is trying to do, what your assignment currently is, or in what way exactly you're stuck.
