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:
How to download Java applet?
- Let’s see how to download the Java applet from the link above. Right-click on the page and go to view page source or any other option like that in your browser. Now, the Java applets are in the .class extension or in the tag. Press Ctrl + F to search the .class or .
How to extend applet in Java?
- Change int () methods name to the construction. Replace “extends Applet” with “extends frame” for the class. Create a new main ()method. Relate “import” statement for class applet. Add window listener’s method to handle window events. Add the “import java.applet” statement. Replace, “extends frame” with “applet”.
What happened to Java applets?
- Java applets used to be able to run from a web browser, but support for Java applets in modern web browsers has been largely phased out due to security concerns. They were a popular way to provide interactive web page content, but they have fallen out of favor recently.
How do I make an applet available to the user?
- Your applet is complete. Now you need to make it available to the user. To do so, you create a web application, put the applet JAR on its classpath, and then add an applet tag to the web application’s HTML file. Choose File > New Project. Select Web Application in the Java Web category. Click Next.
