Java programming: JDK???

Question

I have BlueJ as the IDE and the version of java is 1.3......How do i install a new JDK.......that is...how do i get java version 1.4??

Answer 1

You can get the JDK from http://java.sun.com/javase/downloads/index.jsp and then you have to let BlueJ that you want to use the new version by running the "vmselect" program (at least that is what says about it on the web page for your IDE. Also if you really want the 1.4 JDK I saw the install for it listed at the top when search with JDK on www.google.com

Please note Sun is already at JDK 6. Also note that 1.3 is also known as JDK 3, and JDK 1.4 would be JDK 4, and so on.


BlueJ web page:
Step 3: Installation

Windows:

Double-click the install file (bluejsetup-213.exe).

This will run a standard installation. Follow the instructions on screen. The installer will install the executable bluej.exe. Execute this to run BlueJ.

If you have more than one Java version installed, BlueJ will let you select your preferred version the first time it is executed. This can be changed later by running the "vmselect" program, which will be installed into the same directory as BlueJ.
