Internet Programming with Java

Introduction to Object-Oriented/Internet Programming with Java III




The objective of this course is to help you to understand some fundamental basic concepts behind the Java technology. The audience is assumed to have little or no prior exposure to Java and Object-Oriented programming. Here we will cover the basics of the Java technology. The topics will help you to understand how to use Java to create, access, and support Java applications and applets. We will also discuss the portability features of Java and how they are changing the way Web users access applications at the desktop level.

In the next few sessions, we will:

Exercise


The HelloWorldFrame application


At the last session, we did a study of the HelloWorldFrame Java application. We will now start modifying that program to incorporate new elements. The resulting program will do the following:

The Java application will display a button with "Hello World" and when the button is pushed an odd number of times, the button will display "I am odd" and the same message is printed to the console. When the button is pressed an even number of times, the button will display "I am even" and the same message is displayed to the console.


Here a set of code fragments will be supplied, and you will put them together and create the program that would accomplish the above tasks.
