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.

The Graphics class is the abstract super class for all graphics contexts which allow an application to draw onto components that can be realized on various devices, or onto off-screen images as well. A Graphics object encapsulates all state information required for the basic rendering operations that Java supports.
What shapes can you make in Java?

A Canvas component represents a blank rectangular area of the screen onto which the application can draw or from which the application can trap input events from the user. An application must subclass the Canvas class in order to get useful functionality such as creating a custom component.
How do you draw an arc in Java?
To draw a circle keep the width and length the same. Used to draw an arc inside an imaginary rectangle whose upper left corner is at (x,y). The arc is drawn from the startAngle to startAngle + arcAngle and is measured in degrees. A startAngle of 0º points horizontally to the right (like the unit circle in math).
How do you make an ellipse in Java?
In this article we will draw a ellipse on Java applet by two ways . By using the drawOval(int x, int y, int width, int height) or by using mathematical formula (X= A * sin a, Y= B *cos a, where A and B are major and minor axes and a is the angle ) . Similarly, we will draw a rectangle on Java applet by two ways .
How do you make a square in Java?
To draw a square we need to know that: A square has a width and a height, both are equal size. The way to draw a square in Swing is with drawRect(x, y, width, height) draw(Shape) of the Graphics2D method where Shape would be an instance of Rectangle2D.
Can you make 3d games with Java?

What is a Graphics object?
Graphics objects are the components used by MATLAB® to create visualizations of data. Each object plays a specific role in the graphics display. For example, a line plot consists of a figure object, an axes object, and a chart line object. You can customize graphics objects by setting their properties.
