java实现--简易扑克牌游戏

第三季听课后的综合实战，要求如下：
1.创建一副扑克牌，不考虑大小王
2.创建两名玩家，玩家至少要有ID、姓名、手牌等属性，手牌为扑克牌的集合
3.洗牌，将之前创建的扑克牌顺序打乱
4.发牌，将洗牌之后的扑克牌集合，从第一张开始，发给两名玩家，按照一人一张的方式，每人发两张
5.开始游戏，比大小，大小相同比花色（黑红梅方）

实现代码如下：

扑克类

public class Poker {
public Integer color;
public Integer number;
public Integer dengji;//等级属性，用于之后的比较大小

public Poker(int color,int number){
this.color = color;
this.number = number;
this.dengji = color + number;
    }

    @Override
public String toString() {
        String colorString = "";
        String numberString = "";
switch(color){
case 0 : colorString = "方片";break;
case 13 : colorString = "梅花";break;
case 26 : colorString = "红桃";break;
case 39 : colorString = "黑桃";break;
        }
switch(number){
case 11 : numberString = "J";break;
case 12 : numberString = "Q";break;
case 13 : numberString = "K";break;
case 14 : numberString = "A";break;
default :numberString = String.valueOf(number);break;
        }
return colorString + numberString    ;
    }
}

玩家类

public class Player {
public Integer id;
public String name;
public List<Poker> playerlist;

public Player(Integer id,String name){
this.id = id;
this.name = name;
this.playerlist = new ArrayList<Poker>();
    }
}

游戏具体实现

public class PokerList {
public List<Poker> pokerlist;
private Scanner console;
private Player player1;
private Player player2;

public PokerList(){
this.pokerlist = new ArrayList<Poker>(52);
this.console = new Scanner(System.in);
    }

//创建一副扑克牌
public void newPoker(){
for(int i = 0 ; i < 4 ; i++){
int color = i * 13;
for(int j = 0 ; j < 13 ; j++){
int number = j + 2;
                Poker poker = new Poker(color,number);
                pokerlist.add(poker);
            }
        }
    }

//遍历输出
public void eachPoker(){
for(Poker po : pokerlist){
            System.out.print(po.toString() + ",");
        }
        System.out.println();
    }

//洗牌
public void shufflePoker(){
        Collections.shuffle(pokerlist);
    }

//创建玩家并发牌
public void dealPoker(){
        System.out.println("请输入第一位玩家的id和姓名");
        System.out.println("输入id:");
        Integer id1 = console.nextInt();
        System.out.println("输入姓名:");
        String name1 = console.next();
        System.out.println("请输入第二位玩家的id和姓名");
        System.out.println("输入id:");
        Integer id2 = console.nextInt();
        System.out.println("输入姓名:");
        String name2 = console.next();
        System.out.println("******欢迎玩家:" + name1);
        System.out.println("******欢迎玩家:" + name2);

        System.out.println("******开始发牌******");
        player1 = new Player(id1,name1);
        player2 = new Player(id2,name2);
        player1.playerlist.add(pokerlist.get(0));
        System.out.println("***玩家：" + name1 + " 拿牌***");
        player2.playerlist.add(pokerlist.get(1));
        System.out.println("***玩家：" + name2 + " 拿牌***");
        player1.playerlist.add(pokerlist.get(2));
        System.out.println("***玩家：" + name1 + " 拿牌***");
        player2.playerlist.add(pokerlist.get(3));
        System.out.println("***玩家：" + name2 + " 拿牌***");
        System.out.println("******发牌结束******");
    }

//比较牌的大小
public void comparePoker(){
        System.out.println("******游戏开始******");
        Collections.sort(player1.playerlist);
        Poker p1 = player1.playerlist.get(1);
        System.out.println("玩家：" + player1.name + "最大的手牌是：" + p1);
        Collections.sort(player2.playerlist);
        Poker p2 = player2.playerlist.get(1);
        System.out.println("玩家：" + player2.name + "最大的手牌是：" + p2);
if(p1.number > p2.number)
            System.out.println("******玩家：" + player1.name + "获胜！！******");
else if(p1.number < p2.number)
            System.out.println("******玩家：" + player2.name + "获胜！！******");
else{
            PokerComparator result = new PokerComparator();
if(result.compare(p1, p2) == 1)
                System.out.println("******玩家：" + player1.name + "获胜！！******");
else
                System.out.println("******玩家：" + player2.name + "获胜！！******");
        }
    }

//输出各个玩家的手牌
public void showPoker(){
        System.out.println("玩家各自的手牌为：");
for(Poker po1 : player1.playerlist){
            System.out.print(player1.name + ":" + po1.toString() + " ");
        }
        System.out.println();
for(Poker po2 : player2.playerlist){
            System.out.print(player2.name + ":" + po2.toString() + " ");
        }
    }
}

这里的sort，使用了Comparable接口，需要重写compareTo方法，根据数值比大小

//在Poker类里
@Override
public int compareTo(Poker o) {
// TODO Auto-generated method stub
return this.number.compareTo(o.number);
    }

还是sort，使用了Comparator接口，需要重写compare方法，当数值相同时根据花色比大小
之前的等级属性派上用场了

public class PokerComparator implements Comparator<Poker> {
    @Override
public int compare(Poker o1, Poker o2) {
// TODO Auto-generated method stub
return o1.dengji.compareTo(o2.dengji);
    }
}

结果：

总结：
难的地方在于比较牌的大小，这里重写了compare方法，并给扑克牌设置了等级属性，这里借鉴了http://www.ituring.com.cn/article/18401
