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 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 frontend we will design a beautiful dashboard which gather different components(anchorPanes , imageViews , textFields , labels , buttons , lineChart and combobox)

We will see the apilayer website and various api provided for the currency exchange and understanding some end point and its parameter. we will test distinct http GET request using free tool (reqBin)

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 Connection.

• 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 that we faced before to link it with the frontend.

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 output.
