JDK is available from Sun at http://java.sun.com/javase/downloads/index.jsp and instructions for installing the JDK bundle are posted here by Professor Marateck. (Note: You do NOT need to install JCreator to use NetBeans.)
  2. Go to http://www.bluej.org/netbeans/index.html and select Download the System Here. Be sure to select the correct version for your system (Windows) before you download. You may wish to read the instructions first.


On Mac OS X systems, Java is already available so you do not need to install it.

  1. Current versions are available at http://www.bluej.org/netbeans/index.html. Be sure to select the correct version for your system (Mac OS) before you download. Earlier versions of NetBeans/BlueJ edition can be found here.

Note and Explanation:

NetBeans - BlueJ Edition is available from NetBeans.org. An "IDE" - Integrated Development Environment - is a program that makes it easier to type in Java code and to run the programs. An IDE does not contain the Java itself; that is available from Sun.
