Why is Eclipse not displaying project 'correctly' anymore?

Question

I only have on project and in it, the layout of the project has become 'messed up.' See here:

The dot files are now visible. The src folder is not collapsed anymore... that is to say, the empty folder are now not showing up as one folder anymore.

What the heck did I do here?

Answer 1

I think you've changed from Java perspective to Java EE perspective or what ratchet freak said :).
