Ive been given the assignment to make a GUI for a user to enter test scores and it will tell the user how many test scores the average of the scores and the best test score entered with 3 buttons at the bottom labeled "Enter Score", "Clear" , and "Exit".
I'm having coders block so to speak of i cant figure out how i can have one text field that will hold any number of data entered.

Can you help me?

Thanks for any help!
