添加顶点使用ArrayList中以图形 [英] Adding vertices to graph using ArrayList

问题描述

我想补充创建顶点（SETA，组B）将存储店铺，为后期比较他们，我怎么过，我无法顶点添加到ArrayList两个ArrayList中。

I am trying to add create two ArrayList of vertices (setA, setB) which will store the stores for comparing them late how ever I am unable to add vertices to the arraylist.

这里是code

import java.util.*;


public class BipartiteGraph<Vertex> {

    private String strName;
    ArrayList<Vertex>[] vertexList;

    public BipartiteGraph(){

        vertexList = new ArrayList[2];
        vertexList[0] = new ArrayList<Vertex>();
        vertexList[1] = new ArrayList<Vertex>();
        Scanner vertexInput = new Scanner(System.in);
        int vertex;
        vertex = vertexInput.nextInt();
        for(int i = 0; i < 10; i++){
            vertexList[0].add(vertexInput.nextInt());
        }
    }
}

此外，如果有人能指导我，如果我在正确的方向。

Also if someone could guide me if I am in the right direction.

推荐答案

您正试图 INT 变量添加到顶点<的容器/ code>的对象。假设，你的顶点有一个构造函数接受 INT 你应该宁愿使用：

You are trying to add int variable into the container of Vertex objects. Assuming, that your Vertex has a constructor accepting int you should rather use:

vertexList[0].add(new Vertex(vertexInput.nextInt()));
