I am using Indigo Eclipse for Java as a beginner user. When I press Ctrl+Space to select from the proposal window for HashMap it does not show anything. I did import the library and I did select the Java Proposals from the reference window. What do I do to fix this little problem?

This is what you're looking for. I guess the developers called this a proposal window but Microsoft has always called it intellisense I believe.

I have known that I can get the eclipse SDK. But how can I watch the real code in the SDK. Can someone tell me the detail to watch them?
You can find all source codes you need here:
http://git.eclipse.org/
Eclipse has a lot of sub projects and you probably need a couple of them to be able to build your own ide.
I would start with this github project https://github.com/eclipse/eclipse.platform and work from there.
