First Step towards Java Programming - Downlaod and Install the JDK

Downloading & Installing the JDK

Before you can develop Java applications, you'll need to download the Java Development Kit (JDK). The JDK is a development environment for building applications, applets, and components using the Java programming language. The JDK includes tools useful for developing and testing programs written in the Java programming language and running on the Java platform.You may prefer at a later time to use a third party IDE, such as Visual J++ or Borland JBuilder, but it is important to become familiar with the basics of Java first.

Sun offers many versions of its JDK, for different Java versions and platforms. You are advised to use the most recent JDK, to gain access to all of the functionality of the latest version of the Java platform. If you don't already have the JDK installed, then stop off at Sun's official Java site,
For an even quicker way to find the latest Java tools, visit the JDK Download . The most current version at time of writing is the Java 2 SDK v1.3, which contains all the tools you will need for this tutorial.

Installing the JDK

If you have previously installed older version of JDK/JRE, un-install them. Run "Control Panel" ⇒ "Program and Features". Un-install programs such as "Java SE Development Kit" and "Java SE Runtime". (If you are not sure whether you have older versions of JDK, check!)The installation process is fairly straightforward, but you should consult the documentation if you encounter problems. You'll need to make sure that the JDK is installed correctly, and that the JDK tools are within your operating system's path, before proceeding.
