Question

Having serous trouble with this coding. Similar to findNode, but rather than returning the node that contains the target, instead returns a list of nodes above the one that contains the target, in low to high level order.
* @param node the current node being examined
* @param target the Person being searched for
* @return an ArrayList of nodes that are directly above the
* target in the hierarchy
private ArrayList<MultiTreeNode<Person>> findNodeChain(MultiTreeNode<Person> node, Person target)
{
throw new UnsupportedOperationException("Not supported yet.");
}

What I have tried so far:
private ArrayList<MultiTreeNode<Person>> findNodeChain(MultiTreeNode<Person> node, Person target)
{
return findNodeChain(node, target, new ArrayList<>());
}

Answer 1

create new array
while hasnext
node = nextnode
if node contains target
add to list
return list
