These import statements bring the classes into the scope of our applet class: java applet Applet java awt Graphics Without those import statements the Java compiler would not recognize the classes Applet and Graphics which the applet class refers to The Applet CLASS: Every applet is an extension of the java applet Applet class

Applet Execution An applet is a Java program that runs within a Java-compatible WWW browser or in an appletviewer To execute your applet the browser: • Creates an instance of your applet • Sends messages to your applet to automatically invoke predefined lifecycle methods The predefined methods automatically invoked by the runtime system are:

Running an Applet from an HTML Page The normal way to run an applet is from an HTML document Syntax: Example: Note:use the compiled file extension class not the source extension java

An applet is a Java program that runs in a Web browser An applet can be a fully functional Java application because it has the entire Java API at its disposal There are some important differences between an applet and a standalone Java application including the following: An applet is a Java class that extends the java applet Applet class

an application that stores data onto the host computer; this can only be done by an applet under very strict conditions Example Write a Java applet that converts U S dollars to Japanese yen For example $10 00 = ¥931 10 import java applet Applet; import static javax swing JOptionPane *; import java text DecimalFormat;

A piece of code that can be run by a java-enabled browser 30 Making an Application an Applet import java applet * Have the class extend Applet –Applet already extends Panel – Typically just put a Panel inside of the Applet and you are set – No main needed import java applet *; public class BasicGUIApplet extends Applet

4 Test the applet code with the help of java-enabled web browser or appletviewer Step 1: Writing Applet code While writing applet code we have to use two main classes Applet and Graphics For using Applet class we have to import import java applet *; For using Graphics class we have to import Abstract Windowing Toolkit(awt) as follows

Example (1) :Write java applet program to display the string “My first Java applet” on the applet viewer with x=50y=50 fig(1) show the output of the program Solution: import java applet

import java applet Applet;import java awt Color;import java awt Graphics;import java util Random; public class DrawingStars extends Applet {private static final long serialVersionUID = 1L; public void paint(Graphics g) {Random rand = new Random();int[] xCords = new int[10];int[] yCords = new int[10]; 1 5; radiusDiff; outerRadius); outerRadius);

applet from using the applet method getCodeBase and the URL that the document ( html) was loaded from using the getDocumentBase method In summary to load an image in an applet the statement is Image image1; image1 = getImage(getCodeBase() filename); Then you draw the image on the screen yourself in the paint method:
