Create A GUI JavaFx Currency Exchange With Clean Java Code

In this course we will create together a JavaFX desktop application for Currency Exchange, we will create the graphical user interface using scene builder, by the way, scene builder is free and open source and it is based on Drag & Drop user interface design allows for rapid development.

We will design the GUI (frontend) separated from the java backend code.

For the front, we will design a beautiful dashboard that gathers different components(anchorages, image views, text fields, labels, buttons, Rinehart, and Combobox)

We will see the player website and various APIs provided for the currency exchange and understand some endpoints and its parameter. we will test distinct HTTP GET requests using a free tool (regain)

we will also try to focus on oriented object programming and  java for the backend with clean, maintainable, and flexible code, we will split each functionality alone into separate classes:

• classes to interact with remote API Connections.
• controller class to interact with the view model (FXML file in our case).
• models classes to create the objects fetched from the remote API.
• services class for the business logic and different functionalities to deal with the user input.
• class to implement an interface that contains all the needed methods in our project.

we will test the whole backend in the main method and fix all the problems which we faced before to link it with the front.

finally, we will finalize our project by implementing all methods inside the dashboard controller class, this class has a direct interaction with the user input, and result in output.
