That's the GUI

^^ that's my program.

I want the buttons on that GUI to show the contents in the arrays on Interface in the place that says On The Shelf. So I click room 1 and it shows me the contents in that first array.

To be even more clear:

I have been trying to get the those buttons to show me the contents of the array that i made in my Interface class. So button1 for [0][0]. I'd like if it would show the contents/items in the textfield that's called "On The Shelf".

So basically I need actionListeners set up to show me the contents and the original room description/name when I click a button.
