To start programming in Java, you need two things. First a Java Compiler and Second a text editor that will compile and run your coding. To get the Java Compiler, you will need to install the Java Development Kit (JDK).Next, you will be installing a free text editor where you can write and run your Java programs. This section is subdivided to guide you through the entire process of setting up your tools for java programming.

Downloading and Installing JDK

If you are a Mac user, you do not need to download the JDK. Mac OS X comes with a fully configured and ready-to-use Java runtime and development environment. Mac OS X includes a full version of J2SE 1.5, pre-installed with the Java Development Kit (JDK) so you don't have to download, install, or configure anything.

For Windows users, the JDK is the first thing you need to install before creating and running Java programs on your home computer. The JDK allows your computer to create and run Java programs.

Below is the link to download JDK and installation instructions. There are several downloads available at this link. You need the Java SE Development Kit. You do not need any of the bundles. (See diagram below)

Downloading and Installing Dr Java

Dr Java is a text editor for writing, compiling and running Java programs. It is designed primarily for students, providing an intuitive interface and the ability to interactively evaluate Java code. It also includes powerful features for more advanced users. Dr Java is available for free under the BSD License, and it is under active development by the Java PLT group at Rice University.

Test Run

To test run, run "Dr Java". If your installation is successful, you will see the following diagram.

Congratulation, you have successfully install the tools need for Java programming.
