I added highlight tags for you this time. Don't forget them in the future.

Slow down. What is your goal? What do you expect this code to do? What exactly does it do instead? You'd probably be better off asking a more specific question and posting an SSCCE instead of just dumping all your code here. For example, if your question is about adding an ActionListener, then create a program with a single button and add an ActionListener to it.

Edit- Good lord, why don't you use a layout manager like a sane person?

Your class is missing main method:

	public static void main(String[] args) {
		Calculator cal = new Calculator();
	}

immutable objects

It is possible that the main method is in a different class. Not all classes need a main method.

Huh? Where? He extends JFrame.
