I primarily use JDeveloper 10 with JDK 1.4.2 on Vista. I would like to install Eclipse and have it run the latest JDK 6.
Is this possible without conflict?
Ideally I would like to just use JDeveloper and switch back/forth between JDK versions. Is this possible?

It is very possible to run multiple versions of Java on the same machine so you can run your existing applications and Ignition at the same time.
Yes, you can. Just use full path names when invoking javac , java , etc. or set your PATH environment variable to point to the appropriate jdk/bin location. The IDEs usually allow defining multiple JDKs/JREs, and you can choose which one to use for every project.
Look at the picture below, we have installed two JDK's of version 16 and 17 respectively in the folder F:\Java. According to your requirement, You can download JDKs of different versions and save them into different folders on different drives. Now open Command Prompt then type java and press enter.
I know you can install both. Java 8 and Java 11 and keep them at the same time...
It is indeed possible, you can have as many JDKs in system as you wish. Just install them into different directories, then you can add a new JDK to your IDE (they support having multiple).
You can choose one on per-project basis.
