Java iterate through different levels of childs

I'm creating a mindmapping application
as of now I have a Node class. This Node object can have several Node objects as childs ( a list of Nodes).

Now as this can have several levels deep how do you iterate through all these Nodes?

Are they arranged in a tree? If so I suggest you look at this http://en.wikipedia.org/wiki/Tree_traversal . There are different ways of going through the tree.
