Creating a JMenuBar with JMenu and Mnemonics

Program Description:

One of the interesting part in programming java that I enjoyed the most is making JMenu, JMenuBar, and JMenuItem because it looks good in the program and it helps you manage and organize everything that is in your program. It is considered as one of the important part of a software. What I like about making JMenu, JMenuBar, and JMenuItem in Java is that it is very easy to create and understand.
