There are several development environments for Java.  Integrated Design Environments are available from Borland, Asymetrix, Symantec, and others, but the original development environment is from Sun Microsystems, the originator of Java.  This is the Java Software Development Kit, or JDK.  The JDK has several advantages, and best of all, it is free.  The entire package can be downloaded off of the net from Sun. 

J2SE 1.5.0 is not the latest version of Java, but will be more widely supported than the current version.

Step 1 - Getting the software

Either version 1.5 or another version of the JDK can be obtained from Sun using the links below.  There are two choices for version 1.5:

Be sure to choose JDK (Software Development Kit) rather than JRE (Java Runtime Environment.)

Step 2 - Installing the software

The programs in the Java Development Kit are not windows programs.  They are run from the command line of a DOS window. 

From a DOS command line, execute the program which has been downloaded, either jdk-1_5_0_14-windows-i586-p-iftw.exe or jdk-1_5_0_14-windows-i586-p.exe.  These are Windows programs. 


Follow the instructions of the installation program.  If the small installation program has been chosen, installation may take hours with a dial-up connection.

Step 3 - Setting up the software

To run the JDK programs, the environment variable path should be set. 

Windows NT/2000/XP/Vista

Windows 95/98/ME

The system will have to be rebooted before these changes take effect.
