Is it possible to simply open a file, save/compile it, and run it? I've been at it for a few hours and I'm only able to run a new class file created under a project. I can not open simply open and run a file, and even with a project up I am unable to bring an existing file into the project; it just opens and I have the same problem.

Is this intentional? Am I missing something? I suppose I could just open the existing files and copy/paste their contents into a New class under a Project, but that seems awfully tedious and far too time-consuming to be reasonable.

Yes, the project is usually what tells Eclipse what you're building against, and allows it to incrementally build your sources as you change them. Past the simple 'Hello, World' case, you won't be dealing with a singular class file.

Yes, you need to have the files in your workspace projects. You can use
File->Import...->General->* to import things into your workspace.
You'll want to import them into a Java Project's source folder.

Eclipse is really for building applications.

In my most active work spaces, I keep a scratch project around in which
I can just throw something quick to try out
