I haven't heard of this description. It seems to correlate with a classes relationship to an interface it implements - is that correct? Thanks

I've also never heard of "is-like-a". Where did you read / hear about that term? The "is-a" relationship is also valid for classes that implement interfaces.

As Jesper said, "Is-Like-A" is not a standard term in OO lingo. The closest programming construct I can think of that might correspond to this relation are delegates in C# and other .NET languages, which give you a way to describe similarity in behavior without an inheritance relation. But I don't think Java has anything quite like this, and the SCJP exam definitely won't use this term.
