Create a Java Applet Those of you who purchased my latest book, Learn to Program with Java, know that in the book, we create a Java program designed to calculate grades for the English, Math and Science departments of a university. At the completion of the book, we have a working Java program that uses a windows Interface to prompt for grade components, and then displays the results. In this article, I'm going to show you how to take the project and modify it so that it can be displayed in a web page.

This program illustrates you to display image in an applet which has been done in this example. Display image in the applet Introduction This program illustrates you to display image in an applet which has been done in this example.
In this program you will see that how many methods, classes, packages and it's properties have been used to display the image in an applet. In this program only one function paint Graphics g has used.
Function paint Graphics g is also a part of the life cycle of an applet in which anything you can draw in your applet to appear on the browser. In this function MediaTracker class of the java. MediaTracker is a utility class that tracks the status of a number of media objects.
And this type of object can include images and audio clips. In this program only the explanation about the adding images has been given.
MediaTracker class is used after creating the instance for that and calling the addImage of the MediaTracker class which is used in this program as you can see.
In this program method getImage is used to return the image for the object img of the Image class taking two arguments, first is getCodeBase and another is image name. Then the addImage method of the MediaTracker has been used. Syntax of the addImage function is MediaTracker.
Arguments of addImage function is explained below: Here is the code of the program:Applet Image Java - Read more about applet image tutorials, example to display image in applet, how to write code for applet image, program of applet image in java programming.

Next, paint() method was automatically called to draw the applet window to display it to the user and within the paint() method, drawString() method is called a few times to write text messages, displaying us the order in which each applet method was called during our interaction with the applet window.

A Java applet is a Java program written in a special format to have a graphical user interface.
The graphical user interface is also called a GUI (pronounced "gooey"), and it allows a user to interact with a program by clicking the mouse, typing information into boxes, and performing other familiar actions.
Applet is a Java program that can be transported over the internet and executed by a Java enabled web-browser(if browser is supporting the applets) or an applet can be executed using appletviewer utility provided with JDK. This compilation is dedicated to the memory of our nameless forebears, who were the inventors of the pens and inks, paper and incunabula, glyphs and alphabets.
