I am creating a simple GUI in Java for a bank account and I want to add an addBalance button with a text box so that users can initialize their balance instead of having to start by making an initial deposit first. Once they add their balance it should display in the current balance text box area. How do I do that? Also if you have any design ideas feel free to toss that in as well. I appreciate any knowledge you can give me. Thank you and have a wonderful day!
