    Default GUI

    I've created a program which works well, though I want to now change it into a GUI, would it be better if I integrate GUI code into existing classes or have a separate GUI class which brings together existing classes into an interactive format?

    The program replicates buying items off a website so the GUI would be of a browser. It would be extremely simple, just wondering how to structure it.

    In the spirit of pushing you towards an MVC design where there are code components that represent the View (the GUI), the Model (the data) and the connection between the two (the Controller), I suggest you separate the code you have into those parts. It's hard to give specific suggestions without seeing what you have, but imagine separating your existing code into user input (which will become the GUI) and the program logic - reactions to the user's input, data crunching, manipulation, etc. Ideally, the resulting resulting program design would plug in either a component that allows console input or GUI input with little to no change to any other code.

    If you didn't build your code with this goal in mind from the start (and I assume you didn't), then it's likely going to be difficult to draw clear boundaries and make non-intrusive separations. You may find it easier to start over, reusing the logic portion of your existing code when you can. Even though starting over may be easier, the task of separating what you have into stand-alone components may take longer but in the end provide a more significant opportunity to learn valuable lessons. You decide.

    Thank you for your advice, I didn't structure my code on the basis of implementing a GUI down the line so I need to start from scratch.
    Thanks anyway.

    GUI in java has two packages such as AWT and Swing toolkit. Other java components for GUI applications are SWT, SwingX, etc. And JavaFX is a package which consists of rich set of media and graphics and helps to design , create and test GUI applications.
