Output:
Discussion:

1. I used netbeans to run the program.

2. I used jframe to build this program.I used design window to design the
working window and source to write the codes.
3.For design window , I used Label and text fields.
For the code , I used Random Class to generate random variables.getText &
setText helped to scan the user input & print the result.
4. I ran into some problem while doing this lab project but finally overcomed
it after trying some times.
