题目是要写一个带权有向图的程序.如下
public class Graph {
public Graph(int maxVertices) { … }
public int getNumVertices() { … }
public MyVertex[] getVertices() { … }
public int insertVertex(MyVertex v)
public int getEdge(int inVertex, int outVertex)
public boolean setEdge(int inVertex, int outVertex, int weight)
public boolean insertEdgeDirected(int inVertex, int outVertex, int weight)...

可是题目一开始还要求用一个interface
public interface MyVertex {
public String toString();
}

我一开始是用一个一维数组来存vertex (protected int[] Vertexs;)
用一个2维数组来存edge (protected int[][] Edges;)

但我仔细看了一下题目发现这样定义不对
是不是应该这样定义:
public class Vertex implements MyVertex{..}
public class edge{..}

谢谢！！
