Thread: 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");
