I am a beginner and i am working on eclipse . I started to modify some component. I am trying to add a new path option in installed JRE under preferences through the code without the wizard, but in order to do that i am not able to understand which class to follow so that i could actually go ahead.
So can anyone please guide me.

It would help to know what you are trying to accomplish. But the list of known JVMs is managed by the JDT/Debug component in org.eclipse.jdt.launching. The key class is org.eclipse.jdt.launching.JavaRuntime, interfaces are IVMInstall.

The IDE is itself a great example to learn from. Within the IDE, use Alt-Shift-F1 to invoke the PDE Plugin Spy find out the what implements the view or editor or dialog that you're currently examining, and start poking through the code. Take a look at the Preferences > Java > Installed JREs preference page, for example, to see what it does to list and add to the list of known JREs.

I've attached an Oomph task implementation that's designed to create a new JRE entry. You should get the general ideas for how to do this programmatically from this.
