Java: how to represent graphs?
- by Rosarch
I'm implementing some algorithms to teach myself about graphs and how to work with them. What would you recommend is the best way to do that in Java? I was thinking something like this:
public class Vertex {
private ArrayList<Vertex> outnodes; //Adjacency list. if I wanted to support edge weight, this would be a hash map.
//methods to manipulate outnodes
}
public class Graph {
private ArrayList<Vertex> nodes;
//algorithms on graphs
}
But I basically just made this up. Is there a better way?
Also, I want it to be able to support variations on vanilla graphs like digraphs, weighted edges, multigraphs, etc.
