Question

I’ve defined a sub-class and want to have two constructors with different parameters. It looks like this

public class GraphNode extends Entity{
   protected String id;

   public GraphNode(PVector pos, String id) {
       super(pos,0);
       this.id = id;
   }

   public GraphNode(PVector pos, String id, List<GraphEdge>) {
       this(pos, id);
       //do something else
   }
}

The compiler keeps telling me that:

Duplicate method GraphNode(PVector, String) in type
GraphNode

What am I doing wrong?

You forgot to give your third argument a variable name:

public GraphNode(PVector pos, String id, List<GraphEdge> list)
