Example of simple applet using object of graphics class

You will have seen many applets that use objects of the Graphics class. For example, a Graphics object is the argument automatically passed to the applet when the system invokes the paint() method.

Consider the output of this applet:

The applet producing this output is as follows:

import java.applet.Applet;

import java.awt.*;

public class DrawString1 extends Applet
{

public void paint( Graphics g )
{
g.drawString( "text drawn with Graphics method 'drawString()'",
20, 20 );
}

} // class

Here a messagedrawString(...)is passed to the Graphics object g— resulting in the invocation of the drawString()method of the class Graphics.
