How can I implement an abstraction into this colde?

Warzombie3701 (28)
My code is almost done but College Board is being a bitch again and requires an abstraction for me to get a good grade but my code is working fine without it and its too late to make a new idea. Help?

but my teacher requires an abstraction
Tell your teacher, there is no gain in touching a running system and perhaps jeopardize it only for an improper specified "abstraction". Take only action if you know you will get the promised good grade by reworking the code, all else is not effective and wasting time. Time is something you'll never get back if you spent it for nothing.

Probably should have specified since it was College Board that made the rules, I'll change my post now

And do you know what they mean by "abstraction"? It's a pretty general term... I'm not exactly sure what they want just based off your description.

You could wrap everything in a useless class, and call "bankAccount.process()", which calls the code that is currently in main.
