Here are the instructions for downloading JDK (Java Development Kit) and the JCreator IDE (Integrated Development Environment). You may prefer to download JDK as a step in the downloading of JCreator. Both of these programs are free.

The JDK bundle contains among other things, the java compiler (javac) which produces java bytecode. It also contains the java interpreter (java) which executes the bytecode, i.e., runs your program.

We say that JCreator is a "thin layer" above the JDK. This means that it does not contain the compiler or the interpreter (it points to JDK); but it will enable you to compile, debug and run your programs by chosing menu options. For instance, if you make a compilation error, JCreator displays the error messages in a separate window. When you double click a given error message, JCreator will point to the offending line in your program. This is very helpful, especially for long programs.

Both of these programs are downloaded in zipped form. In order to unzip them you need WINZIP. If you don't have it, download it from http://www.winzip.com/downauto.cgi?winzip80.exe.

DOWNLOADING THE JDK BUNDLE

Again, you may prefer to download JDK as a step in the downloading of JCreator. However, you may be using a different IDE from JCreator and may have to download JDK separately. Here's how:
  1. Go to the javasoft URL:
    http://java.sun.com/j2se/1.4.2/download.html
  2. Go to : Download J2SE v1.4.2_09 SDK and click the DOWNLOAD J2SE SDK link.
  3. Click the button at mid page to ACCEPT the licensing agreement.
  4. On the next page under Windows Platform-Java(TM)... click the Windows Off-line Installation link which is to the left of J2SDK-1_4_2_09-Windows-i586-p.exe. A dialog box will open with Save it to Disk clicked. Click OK. The system will automatically choose a directory for you for the download, or you may choose your own.
  5. After some time the download is complete. Then after closing all applications, go to the jdk directory or the one the program setup for you, and click the jdk-1_4_0-win icon. Click the Wizard button at the upper right of the Winzip window. This will automatically unzip the jdk bundle.
  6. Follow the wizard instructions, clicking next and yes when appropriate; also choose the desired directory and hit save. Finally click finish.

  6. After the installation is complete, launch JCreator from the icon that was placed on the desk top.
  7. The first window to appear is File associations. Just click next.
  8. The next window asks for JDK home directory. Browse for the directory and click next.
  9. The final window asks for JDK JavaDoc directory. If you already downloaded the JavaDoc file, browse for it and click finish. Otherwise click finish to continue on without the documentation.
  10. To compile and run a program, use the "Build" menu.

If for some reason, you haven't pointed JCreator to the JDK, do the following:

  1. To point JCreator to the JDK folder, start by clicking Configure/Options/Editor.



    Click JDK Profiles. In the JDK Profiles window, the Default classpath of the selected JDK profile slot must have information in it. If not, click the JDK version 1.3 or JDK version 1.4 profile at the top of the window.



    Then click Edit, and in the Classes window click Add and then



    choose Add Path and select the folder containing the JDK documentation,



    and click OK. Then in the Classes window, the JDK directory will appear at the bottom of the list:



    Then click OK and finally, OK in the original window.

  2. Agree to the licensing agreement by clicking the ACCEPT button and a new screen appears.
  3. Click the J2SE 1.4.2 Documentation button, then be sure that Save this file to disk is clicked and click OK.
  4. Choose a directory for the download to be stored.

  6. To have JCreator point to the Java docs, go to Configure/options/Editor. Click JDK Profiles. In the JDK Profiles window, the Default classpath of the selected JDK profile slot must have information in it. If not, click the JDK version 1.3 or JDK version 1.4 profile at the top of the window.



    Then click Edit, and then the Documentation tab. In the Documentation window click Add and then choose Add Path and select the folder containing the JDK documentation, and finally hit OK. Finally click the OK buttons until all the windows are closed.
  7. You will then be able to access the documentation supplied by Sun by going to the Help menu in JCreator.
