What is the Graphics class in Java?
The Graphics class is the abstract base class for all graphics contexts that allow an application to draw onto components that are realized on various devices, as well as onto off-screen images. A Graphics object encapsulates state information needed for the basic rendering operations that Java supports.
How are Graphics made in Java?
There are several ways to create graphics in Java; the simplest way is to use java. awt. Create a JFrame object, which is the window that will contain the canvas. Create a Drawing object (which is the canvas), set its width and height, and add it to the frame.

What is the difference between Graphics and Graphics2D?
The two basic objects are called Graphics and Graphics2D. Graphics is the parameter of the paint method and a Graphics2D object may be created from a Graphics object. In the original we use methods to draw shapes. The two dimensional version uses objects to hold shapes and a single method draw to display them.
How to draw a line in Java’?
A line is a graphics primitive that connects two points. In Java, to draw a line between two points (x1, y1) and (x2, y2) onto graphics context represented by a Graphicsobject, use the following method: drawLine(int x1, int y1, int x2, int y2).
What is graphics in Java?

What is graphics object in Java?
Graphics Objects. In Java all drawing takes place via a Graphics object. This is an instance of the class java.awt.Graphics. Initially the Graphics object you use will be the one passed as an argument to an applet ‘s paint() method. Later you’ll see other Graphics objects too.
