Traverse on object references

Hey,

I want to traverse on the object references and on their references...

I know the bfs/dfs algorithm for traverse on a graph.

My problem is how to implement it in Java.

How to know what are the references (i think reflection is too much complicated here)

I need to implement it in order to have the ability to create diff engine that compare two objects including their references.

Can some one recommends on utility, design pattern, articles協or this?

Thank you
