Question

我是否可以知道如何序列化和反序列化此程序，我无法弄明白，我是否应该使用数组来存储正在打印的内容..？

它有两个单独的calss文件中的两个类。一个是玩家，另一个是SnakeAndladder1

Player class
------------

package coll.org;

public class Player {

private String name;
private int score;

Player(String name) {
    this.name = name;
}
public String getName() {
    return name;
}
public void setName(String name) {
    this.name = name;
}
public int getScore() {
    return score;
}
public void setScore(int score) {
    this.score = score;
}   

}


SnakeAndladder1 class
---------------------


package coll.org;

import java.util.ArrayList;
import java.util.Hashtable;
import java.util.Map;
import java.util.Scanner;

public class SnakeAndladder1 {
ArrayList<String> name1=new ArrayList<String>(); //an array to store players names

public int throwdice() //to calculate the dice value
{
    return (int)(Math.random()*6)+1;
}

public int ladder(int curscore)
{
    Hashtable<Integer,Integer> ld = new Hashtable<Integer,Integer>();

    //Map<Integer,Integer> ldmap = new Map<Integer,Integer>();
    ld.put(15,30);
    ld.put(45,71);
    ld.put(25,62);
    ld.put(81,91);
    ld.put(9,39);
    while(curscore!=15 || curscore!=45 || curscore!=25 || curscore!=81 || curscore!=9)
    { return curscore;}
    int v=ld.get(15);
    return v;

}
public int snake(int curscore)
{
    Hashtable<Integer,Integer> ld = new Hashtable<Integer,Integer>();
    ld.put(29,11);
    ld.put(81,48);
    ld.put(30,6);
    ld.put(92,71);
    ld.put(58,19);
    while(curscore!=29 || curscore!=81 || curscore!=30 || curscore!=92 || curscore!=58 )
    {return curscore;}
    int v=ld.get(curscore);
    return v;
}


public boolean Game (Player p){
    //int score=0;
    //String name;
    int v=0;
    //name=name1.toString();
        System.out.println("Click y to roll dice");
        Scanner in2=new Scanner(System.in);
        String yes=in2.nextLine();
        if(yes.equalsIgnoreCase("y"))
        {
            v=throwdice();
            System.out.println("dice value:"+v);
        }
        p.setScore(p.getScore()+v);
        if(p.getScore()==100)
        {
            System.out.println("User:"+p.getName()+"got"+v+".Winner!!!");
            return false;
        }
        if (p.getScore()>100)
        {
            p.setScore(p.getScore()-v);
            System.out.println("Current score of"+p.getName()+"is"+p.getScore());
            return true;
        }

        int s1=ladder(p.getScore());
        if(s1==p.getScore())
        {
            p.setScore(snake(p.getScore()));
            System.out.println("Current score of"+p.getName()+"is"+p.getScore());
            return true;
        }
        else
        {
            p.setScore(s1);
            System.out.println("Current score of"+p.getName()+"is"+p.getScore());
            return true;
        }


}

public static void main(String[] args) {
// TODO Auto-generated method stub
int l=0;
//boolean flag=true;
System.out.println("Enter the number of players:");
Scanner in=new Scanner(System.in);
int n=in.nextInt();
System.out.println("Enter Players names in order:");
ArrayList<Player> p1=new ArrayList<Player>(); //an array to store players names
for (int i=0;i<n;i++)
{
    Scanner in1=new Scanner(System.in);
    String name2=in1.nextLine();
    Player p = new Player(name2);
    p1.add(p);
    //name1.add(name2);
}
//Snakeandladder1[] players = new Snakeandladder1[n];
//ArrayList<Snakeandladder1> player=new ArrayList<Snakeandladder1>();
//for(int i=0;i<n;i++)
    //player.add(new Snakeandladder1());
//  SnakeAndladder1 players[];
//  players = new SnakeAndladder1[n];
SnakeAndladder1 sk = new SnakeAndladder1();
while(true)
{
    for (int i=0;i<n;i++)
    {
        Player p3=p1.get(i);
        boolean flag = sk.Game(p3);
        if (flag == false)
        {System.exit(0);}
    }
  }
}
}

这个程序允许任意数量的玩家并要求用户输入y来掷骰子，我有输出但我无法序列化它。有没有办法在程序执行完成后获取输出并将其序列化？

存在一个整齐的库，用于将对象序列化为XML文件（当然，之后将其反序列化）。它非常简单易用且非常有效。
