java, swing; simple gui where to create objects

Question

I have written a simple Command-Line programm that disolves car license plates. like:

V -> Vienna
la -> Los Angeles

Now I want to make a simple GUI (its my first gui) for that programm. here're my classes:

Dissolver.java // dissolves car plates ; and contains whole logic

DissolverGUI.java // gui for Dissolver

My problem is: where should I create my object of Dissolver in the DissolverGui class?

I hope you are able to understand my problem

Your plan to separate GUI from logic is a noble one. Consider creating your Dissolver in the main method and passing it into the GUI via either a setDisolver(Dissolver dissolver) method or via a constructor parameter. — Hovercraft Full Of Eels

Your question is too broad. It's hard to give an advice without seeing the code. You can try adding a field in DissolverGui class referencing Dissolver and use it from all methods. Suppose the right place to create it is the public static void main(String[]) method which will run the whole program.

As a beginner do not bother yourself about the style, just make the program work as you want.
