Here is my program: The language is obviously Java. Thank you for taking your time to help is you did. I greatly appreciate your services.
The code is used to create a calculator that shall have functions like squaring ,rooting , subtracting , adding , multiplying , dividing , and more if I feel like is necessary in the future.
This program is purely for personal use not for commercial use.
