Big-O summary for Java Collections Framework implementations?

I may be teaching a "Java crash-course" soon. While it is probably safe to assume that the audience members will know Big-O notation, it is probably not safe to assume that they will know what the order of the various operations on various collection implementations is.

I could take time to generate a summary matrix myself, but if it's already out there in the public domain somewhere, I'd sure like to reuse it (with proper credit, of course.)

Anyone have any pointers?
