Sun JDK 1.2 is free and more or less decent. Moreover JDK 1.2 is less buggy, that prev version although both compiler diagnostics and debugger still sucks.

Java Tips

General instructions for using the JDK (Java Development Kit)

  1. Use any text editor to enter the source code for your program. Save the Java source as *.java and the HTML source (for an applet) as *.html. Note that the name of the .java file must be the same as the name of the public class it contains (e.g., the name of the file containing public class hello must be
  2. Use javac to compile programs (e.g., javac
  3. Use java to execute a stand-alone program (e.g., java hello).
  4. Use appletviewer to execute an applet (e.g., appletviewer hello.html). (You can also try using your favorite browser, but be warned that many do not yet support all the features of Java 1.1.)
  5. See the online documentation for more details. A copy should be loaded onto the system you are using as part of the installation process (see the system-specific instructions below for details), or you can browse it at Sun's Web site. This documentation describes the compiler and other tools and includes a complete API for Java's core classes.

System-specific instructions

Windows 95

  1. Open a DOS prompt. It is more convenient to use DOS in a window rather than the whole screen. Control-Alt will switch DOS to a window.
  2. Type the command jdk. This sets the path and classpath correctly.
  3. Proceed as above. Note that some text editors append .txt to the end of the file name. If this happens, the Java compiler will not be able to find the file. The editors pfe and notepad with "all files" selected seem to be able to save files without the .txt suffix. If all else fails, use a DOS or Windows command to rename your file.
  4. Online documentation was once available in file N:\win95\JDK-113\index.doc; clicking on the file name would open a web browser displaying the documentation for you to browse. This documentation seems to have disappeared. Check with the CIRCA support staff if this is a concern, or ask us to do us.


  1. Proceed as above. Available text editors include vi and emacs. (Previously, it was necessary to add /local/java/bin to your path to access the Java compiler, etc.; they now appear to be installed in /local/bin, so no changes to your path should be needed.)
  2. Online documentation is available in file /local/java/docs/index.html; pointing your browser at file:/local/java/docs/index.html will display it.

Using the JDK on your own computer

  1. Follow the instructions on Sun's Web page to download and install the current release of the JDK. Note that you must download documentation separately, but it's probably worthwhile to do so, since the core API specification is included. Approximate sizes are 9.7M for the JDK and 3.3M for the documentation.
  2. Proceed as above.
  3. See the installation instructions for instructions on how to access the online documentation.
