I had try to create a GUI program  that take the radius as input.The program should be able to calculate and display the area of a circle and the surface area of a sphere. Input should be requested from a user. The only required input is a radius.
This is very new to me, and I got stuck.
Can you help me to work this program out, so I can learn how to do it.
Thank you very much for your help.

In order to create program with GUI you need to rely on existing GUI

Noramlly you should create the class which extends JFrame
and then add JTextFiled where user will input radius
and JLabel or another JTextField where you would output the result

As this is academic assignemnet yiou need to create something closer to the final goal than the code you have  - then we cna help you to correct and debug
