Java Platform Standard Edition Development Kit (JDK)

Because we are doing Java development, it would make sense to have the necessary Java tools (for example, compiler) set up. If you do not already have the JDK installed on your machine, or if you have an older version than ones required by JUnit and Ant, you should get the latest version from the java.sun.com website and have it set up on your machine so that commands such as java are in your path.

After downloading and installing Java, you should be able to type the command javaversion to test your setup and ensure you have the correct version of the JDK, as shown next:

C:\anil\rapidjava\timex>java -version java version "1.5.0_06" Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0_06-b05) Java HotSpot(TM) Client VM (build 1.5.0_06-b05, mixed mode, sharing)
