Get a good book which shows you how to do the basics of creating and listening to user input with GUI's.

Re: who can help me with GUI??

What are you trying to do exactly. Are you doing a console app with JOption pane that will write to the console or do you want it to show up on like a GUI?, both are pretty simple. If you are just writing it to console then System.out.print(); will work. If you want to print it to a GUI, you will nees a label, JLabel label = new JLabel(), then set the text of the label to the input you recieved, which I think is a method called setText, so label.setText(inputHere); and I am not sure but I think you might have to repaint.
