Example of Graphics in applet

Program:

 
 import java.applet.Applet;
import java.awt.*;

public class GraphicsDemoProgram extends Applet{

public void paint(Graphics g){
g.setColor(Color.red);
g.drawString("Welcome",50, 50);
g.drawLine(20,30,20,300);
g.drawRect(70,100,30,30);
g.fillRect(170,100,30,30);
g.drawOval(70,200,30,30);

g.setColor(Color.pink);
g.fillOval(170,200,30,30);
g.drawArc(90,150,30,30,30,270);
g.fillArc(270,150,30,30,0,180);

}
}


/*
  <applet code="GraphicsDemoProgram" width="300" height="300">
