i keep getting a null pointer exception when trying to add an object to a priority queue

i initialize the queue:

private PriorityQueue<NodeObject> nodes;

and here i try to add to it:

NodeObject childNode = new NodeObject(child, 1);
nodes.add(childNode);

why doesn't this work? i know my NodeObject is not null because i create it right before i add it.
