I have downloaded BlueJ java, as I e-mailed the course leader, and he says we will be using this in the programming module. I installed it. After installing and loading BlueJ, it says the following message: Error: "BlueJ could not find any Java systems. A JDK/J2SDK must be installed to
run BlueJ." . Then the FAQ guided me to this website to solve this error:http://java.sun.com/javase/downloads/index.jsp
I downloaded JDK 5.0 Update 8, as it seems suitable (I think). Is this the right version to download? Or do I download 'JDK 5.0 Update 7 with NetBeans 5.0' or 'JDK 5.0 Update 6 with Java EE'?
