How must an object diagram look like?

Question

I searched the web, but I find a bunch of very different diagrams. Most of them don't even look like object diagrams. They have no object's value. I want to know how I must draw an object diagram in such a way, that my prof won't tell me it's absolutely wrong. Any good tutorial link is highly appreciated!

I recommend attending your lectures. FWIW, you don't usually draw object graphs in design diagrams, class diagrams are much more common. — millimoose, May 02 '09 at 11:51

An object uml diagram probably should look like this. You can find lots of examples on the net. Good luck

You're probably thinking of a class diagram, that shows the relationship between classes (not object instances), right?

UML (Unified Modeling Language) is the standard way of doing this.

Object diagrams tend to have limited use (they're usually working for other diagrams). I suspect you want a class or communication diagram. A class diagram will have fields but no values, while a communication diagram includes messages.

This is an object diagram. There is a more detailed description as part of this tutorial.

Read this page for the different uses of class diagrams, and this for a tutorial.

Here are two examples of communication diagrams.
