I'm trying to make a game similar to Risk where each territory on the map is an object of a class I made, Territory. In order to create the game map I would like each Territory object to be linked to the other territories that would be adjacent on the game board. Is there a way in Java to create some kind of data structure that can store all the objects and with links to their "neighbors"? Or is there a way to have objects store references to other objects like you could with pointers in C?

You can either have the neighbours of every instance of Territory stored in the instance like this: 

public class Territory{
     private ArrayList<Territory> neighbours;
}

or map all territorys to their neighbours like this:

HashMap<Territory , List<Territory>> neighbours;
