Need Help With Creating a Program

Hey everyone! As the title suggests, I need help with a simple Java program. I need this program to be able to rename a file with the push of a button. I also need it to be able to rename the file back to it's original name when necessary. Users are going to be interacting with this program, so it needs to be sleek and easy to understand.

If someone could walk me through the steps of making a program like this, that would be great!

Sincerely, Nerdy Otter

You could start by building the GUI with buttons and text boxes with no function.
And then you could apply methods to them.
If you need help with the GUI or the methods you can ask again.
