how do i fix the following design issues for the program:

here are two design issues with the program.

1. Never use the program name to be extended or a part of the program. There should have been a separate class for generating the GUI interface.
2. Limit the main () element coding to the basics. Have it call methods that do the work of the program, like entering values and displaying results.
