Java學習--撲克牌比大小的小遊戲

實現：生成五十四張牌，然後進行洗牌，輸入兩名玩家，然後分別發兩張牌，進行比較大小，兩張牌中擁有較大一張牌的玩家獲勝

Card.java程式碼如下：

package com.cardgame;

public class Card {

    String suit= new String();
    String num = new String();
    public Card(String suit ,String num){
    
        this.suit=suit;
        this.num=num;
        
    }
}

Player.java程式碼如下：

package com.cardgame;

import java.awt.List;
import java.util.ArrayList;

public class Player {

    String name= new String();
    String id = new String();
    java.util.List<Card> cards= new ArrayList<Card>();
    
    
    public Player(String name,String id){
        this.id=id;
        this.name=name;
    }
    
}

 

MainClass.java程式碼如下：

package com.cardgame;

import java.util.ArrayList;
import java.util.Iterator;
import java.util.List;
import java.util.Random;
import java.util.Scanner;

public class MainClass {

    public List<Card> cards= new ArrayList<Card>();
    public List<String> suitList= new ArrayList<String>();
    public List<Card> upsetCards= new ArrayList<Card>();
