Hello Everyone,
I am having trouble getting a display of my program on the JTextArea "DisplayWindow". My code works and compiles but i do not know how to transfer the program to run on the GUI. It is really simple and I just want it to display and accept the inputs just like the program does. I have attached my code and attached the code to the GUI. Please help with any suggestions. I am not sure how to get them to run together. Thank you!!!
