Java is known as Internet-based language (one of the features of Java) due to Java Applets and Servlets. Applets lie on the client-side to communicate with Servlets on server-side.
Java comes with two types of programs – Applications and Applets.
The basic difference is that applications contain manin() method and applets do not. Moreover, Java Applet comes with special methods like init(), start() and paint() etc.
Following example on Java Applet Demo.java that prints Hello World on applet window.
import java.applet.Applet;
import java.awt.Graphics;
public class Demo extends Applet
{
public void paint(Graphics g)
{
g.drawString("Hello World", 50, 100);
g.drawString("Best Wishes from way2java Readers", 50, 125);
}
}
To run the above Demo applet, write one more file First.html.
Write source codes and execute the applet as in following screen.
