学校作业-斗地主随机发牌并保留底牌且对玩家手牌排序
斗地主系统
该系统是学校作业，java实现的不完善斗地主系统，仅实现了发牌功能。
效果
如下:
Card类
Card类主代码
public class Card {
public int cardSuit;
public int cardPoints;
public Card(int suit, int points) {
this.cardSuit = suit;
this.cardPoints = points;
}
@Override
public String toString() {
switch (this.cardPoints) {
case 11:
return Suit.valueOf(this.cardSuit) + " " + "J";
case 12:
return Suit.valueOf(this.cardSuit) + " " + "Q";
case 13:
return Suit.valueOf(this.cardSuit) + " " + "K";
case 14:
return Suit.valueOf(this.cardSuit) + " " + "A";
case 15:
return Suit.valueOf(this.cardSuit) + " " + "2";
case 16:
return Suit.valueOf(this.cardSuit) + ""; //小王
case 17:
return Suit.valueOf(this.cardSuit) + ""; //大王 为了代码阅读完整性也写上来了
default:
return Suit.valueOf(this.cardSuit) + " " + (this.cardPoints);
}
}
花色通过枚举类实现
enum Suit {
Spade(0), Heart(1), Diamond(2), Club(3), redjoker(4), blackjoker(5); //黑桃（Spade）、红桃（Heart）、方块（Diamond）、梅花（Club）大王（red joker）小王（black joker）
private final int value;
private Suit(int value) {
this.value = value;
}
public static Suit valueOf(int value) {
switch (value) {
case 0:
return Suit.Spade;
case 1:
return Suit.Heart;
case 2:
return Suit.Diamond;
case 3:
return Suit.Club;
case 4:
return Suit.redjoker;
case 5:
return Suit.blackjoker;
default:
return null;
}
}
@Override
public String toString() {
switch (value) {
case 0:
return "Spade黑桃♠";
case 1:
return "Heart红桃♥";
case 2:
return "Diamond方块♦";
case 3:
return "Club梅花♣";
case 4:
return "red joker 大王";
case 5:
return "black joker 小王";
default:
return null;
}
}
}

case 11:
return Suit.valueOf(this.cardSuit) + " " + "J";
case 12:

case 13:

return Suit.valueOf(this.cardSuit) + " " + (this.cardPoints);
}
}
enum Suit {
Spade(0), Heart(1), Diamond(2), Club(3), redjoker(4), blackjoker(5); //黑桃（Spade）、红桃（Heart）、方块（Diamond）、梅花（Club）大王（red joker）小王（black joker）

}
@Override

case 1:

case 4:

玩家类
package com.ysysimon;
import java.util.ArrayList;
public class Player {
public String playerID;
public ArrayList<Card> cards;
public Player(String playerID){
this.playerID = playerID;
this.cards = new ArrayList<Card>();
}
public void showCards(){
System.out.println(cards);
}
}
Main
完整代码:
package com.ysysimon;
import java.util.ArrayList;
import java.util.Collections;
import java.util.Comparator;
import java.util.Random;
public class Main {
public static void main(String[] args) {
// GameBegin
//初始化牌堆
ArrayList<Card> cardHeap = new ArrayList<Card>();
int jokerCounter = 4;
for (int i = 3; i < 18; i++) {
if(i < 16){
for (int j = 0; j < 4 ; j++) {
Card card = new Card(j,i);
cardHeap.add(card);
}
}
else{
Card card = new Card(jokerCounter,i);
cardHeap.add(card);
jokerCounter++;
}
}
//System.out.println(cardHeap);
//初始化牌堆结束
//初始化玩家
Player player1 = new Player("玩家1");
Player player2 = new Player("玩家2");
Player player3 = new Player("玩家3");
//初始化玩家结束
//开始发牌
Random random = new Random();
ArrayList<Card> holecardHeap = new ArrayList<Card>(); //底牌堆
int choose;
for (int i = 0; i <3 ; i++) { //随机抽取3张牌作为底牌
choose = random.nextInt(cardHeap.size());
holecardHeap.add(cardHeap.get(choose));
cardHeap.remove(choose);
}
//System.out.println(cardHeap);
//System.out.println(holecardHeap);
while (!cardHeap.isEmpty()){ //为玩家发牌
choose = random.nextInt(cardHeap.size());
player1.cards.add(cardHeap.get(choose));
cardHeap.remove(choose);
choose = random.nextInt(cardHeap.size());
player2.cards.add(cardHeap.get(choose));
cardHeap.remove(choose);
choose = random.nextInt(cardHeap.size());
player3.cards.add(cardHeap.get(choose));
cardHeap.remove(choose);
}
//对玩家手牌进行升序排序
sortCards(player1.cards);
sortCards(player2.cards);
sortCards(player3.cards);
player1.showCards();
player2.showCards();
player3.showCards();
System.out.println("底牌: "+holecardHeap);
//发牌结束
}
/* 重写排序 */
public static void sortCards(ArrayList<Card> cards){
Collections.sort(cards, new Comparator<Card>() {
@Override
public int compare(Card o1, Card o2) {
// 升序
return o1.cardPoints-o2.cardPoints;
// 降序
// return o2.getAge()-o1.getAge();
// return o2.getAge().compareTo(o1.getAge());
}
});
}
}
其中重写了Comparator以实现自定义类的List的排序
/* 重写排序 */
public static void sortCards(ArrayList<Card> cards){
Collections.sort(cards, new Comparator<Card>() {
@Override
public int compare(Card o1, Card o2) {
// 升序
return o1.cardPoints-o2.cardPoints;
// 降序
// return o2.getAge()-o1.getAge();
// return o2.getAge().compareTo(o1.getAge());
}
});
}
