Thread: Help with GUI

Hello I am trying to get my GUI to create a Usage Object after the user has entered some data. The data are parameters used that make up a usage object. I want call a method on it and then do some sort of calculation once the user has pressed the enter button. Sorry for the classes for being so massive but the user needs to enter a lot of data in order to get the right result. The first class is the gui class and at the moment simply creates a gui. I have a number of inner class that assign the data stored in the text field to the corresponding field in the Usage class. Usage class consists of fields and return statements so not much going on there.

Any help would be great thank you for your time

I am trying to get my GUI to create a Usage Object after the user has entered some data. The data are parameters used that make up a usage object. I want call a method on it

Can you describe what problems you are having?
Do you have a button that should call a method when pressed?
Or do you need to get a reference to an object so you can call its method?
Or what?
