What works: My project as it is now works great for quoting with applicable discounts.
What doesn't: The array code I tried to include. ALSO, I can't seem to figure out how to make it go to the array list display with the user enters "n" when asked if they want to get another quote, it just ends the program.
What I'm looking for: When the user chooses "n" when asked if they would like another quote, I would like to have a rectangle array list of the multiple quotes that shows them:
Shirt Cost Setup Fee Discount Total
I am brand new to Java so I hope I haven't bitten off more than I can chew. I tried reading ahead in our text and have gotten overwhelmed. Thank you for your help!!
