gui in java using graphics classes

How to use Graphics class in Java?
The simplest shape we can draw with the graphics class is a line.
The drawLine() method takes two pairs of coordinates, (x1, y1) and (x2, y2) as arguments and draws a line between them.
The g is the Graphics object passed to the paint() method.
Is JavaFX better than Swing?
JavaFX has a number of advantages over Swing.
It is more lightweight, and has more sophisticated design controls.
It uses CSS styling for components, and XML can be used to develop the GUI layout (with FXML and Scene Builder).
Swing can only be used to create rich client desktop applications.
Graphics is an abstract class provided by Java AWT which is used to draw or paint on the components.
It consists of various fields which hold information like components to be painted, font, color, XOR mode, etc., and methods that allow drawing various shapes on the GUI components._{15 nov. 2022}
