java-图论

基本框架
import java.util.Scanner;

class DenseGraph{
private int n;// 节点数
private int m;// 边数
private boolean directed;// 是否为有向图
private boolean[][]g;
public DenseGraph(int n,boolean directed){
assert n>=0;//断言为真，继续执行
this.n=n;
this.m=0;
this.directed=directed;
g=new boolean[n][n];
}
public int V(){
return n;
}
public int E(){

java-图论最先出现在Python成神之路。
