iterate through recursive objects

Question

I am trying to iterate through a recursive object but Java has no support for this from what I know.

For example, given the object Item:

pub         


        

Answer 1

Something similar to this?

void read(Item item) {
    if (item == null) {
        //do something with the uuid ?
        return;
    } else {
        for (Item i : item.children) {
            read(i);
        }
    }
}
