一、前言
练一个斗地主小游戏，只能发看牌
1.斗地主：
import java.util.ArrayList; import java.util.Collections; import java.util.Scanner; public class PokerPlay2 { public static void main(String[] args) { ArrayList<String> array=new ArrayList<String>(); String []colors={"♣","♥","♠","♦"}; String[] numbers = {"2", "3", "4", "5", "6", "7", "8", "9", "10", "J", "Q", "K", "A"}; for (String color:colors){ for (String number:numbers){ array.add(color+number); } }int count=1; array.add("大🃏"); array.add("小🃏"); while(true){ System.out.println("第"+count+++"局"); Collections.shuffle(array); ArrayList<String> poker1=new ArrayList<String>(); ArrayList<String> poker2=new ArrayList<String>(); ArrayList<String> poker3=new ArrayList<String>(); ArrayList<String> poker4=new ArrayList<String>(); for (int i=0;i<array.size();i++){ String poker=array.get(i); if (i>=array.size()-3){ poker4.add(poker); }else if(i%3==0){ poker1.add(poker); }else if(i%3==1){ poker2.add(poker); }else if(i%3==2){ poker3.add(poker); } } Scanner sc=new Scanner(System.in); String name1=sc.nextLine(); lookPoker("1", poker1); lookPoker("2", poker2); lookPoker("3", poker3); lookPoker("底牌", poker4); }} public static void lookPoker(String name,ArrayList<String> arrayList){ System.out.print(name+"的牌:"); for (String s:arrayList){ System.out.print(" "+s); } System.out.println(); } }
1.1运行结果：
2.斗地主升级版
增加了对牌的排序和地主牌的加入，后续可能会增加玩牌的功能
2.1原理：
斗地主升级版的原理就是，创建HashMap用来后续键找值，然后创建ArrayList
集合（创建其他集合也是可以的）ArrayList集合的作用是用来存储和HashMap
对应的键值，通过两个for进行组合每产生一个就将键值加一，产生不同的键值，
所对应的牌是唯一， 这样为后续排列打下了坚实的前提，然后再创建TreeSet集
合（TreeSet集合可以进行自然排序），然后将ArrayList集合中的元素（其实就是
一些数子，这些数字是HashMap中的键值），分配到三个人上，里面的已经被
TreeSet排序完成，调用方法是通过HashMap将每个人的键值来得到对应的牌。
import java.util.*; public class PokerPuls { public static void main(String[] args) { //定义HashMap集合 HashMap<Integer,String> hm=new HashMap<Integer, String>(); //定义ArrayList集合用来存储编号 ArrayList<Integer> array=new ArrayList<Integer>(); //定义花色和底数数组 String []colors={"♣","♥","♠","♦"}; String[] numbers = { "3", "4", "5", "6", "7", "8", "9", "10", "J", "Q", "K", "A","2"}; int index=0; //注意需要将数字for在外头，否则是按花色排序的 for (String number:numbers){ for (String color:colors){ hm.put(index, color+number); array.add(index); index++; } } hm.put(index, "小🃏"); array.add(index); index++; hm.put(index, "大🃏"); array.add(index); int count=1; while(true){ System.out.println("**********第"+count+++"局斗地主**********"); //洗牌 Collections.shuffle(array); //创建四个牌位分别用来存储三个玩家和三张底牌，因要排序所以用TreeSet集合 TreeSet<Integer> play1=new TreeSet<Integer>(); TreeSet<Integer> play2=new TreeSet<Integer>(); TreeSet<Integer> play3=new TreeSet<Integer>(); TreeSet<Integer> play4=new TreeSet<Integer>(); for (int i=0;i<array.size();i++){ Integer index1 = array.get(i); if(i>=array.size()-3){ play4.add(index1); }else if (i%3==0){ play1.add(index1); }else if (i%3==1){ play2.add(index1); }else if (i%3==2){ play3.add(index1); } } Scanner sc=new Scanner(System.in); System.out.print("第一位玩家:"); String name1=sc.nextLine(); System.out.print("第二位玩家:"); String name2=sc.nextLine(); System.out.print("第三位玩家:"); String name3=sc.nextLine(); lookerPoker("1号:"+name1, play1,hm); lookerPoker("2号:"+name2, play2,hm); lookerPoker("3号:"+name3, play3,hm ); lookerPoker("底牌", play4,hm); int i=0; int num=0; while(true){ System.out.print("几号是地主:"); num=sc.nextInt(); switch(num){ case 1:{i++; play1.addAll(play4);break; } case 2:{i++; play2.addAll(play4);break; } case 3:{i++; play3.addAll(play4);break; } default:{ System.out.println("输入有误，重新输入");break; } } lookerPoker("1号:"+name1, play1,hm); lookerPoker("2号:"+name2, play2,hm); lookerPoker("3号:"+name3, play3,hm ); if (i!=0){ break; } System.out.println("-------游戏结束-------"); } } } //定义遍历方法，并通过存储的index1的键来获取对应的值 public static void lookerPoker(String name,TreeSet<Integer> ts,HashMap<Integer,String> hm){ System.out.print(name+"的牌:"); for (Integer key:ts){ String value=hm.get(key); System.out.print(value+" "); } System.out.println(); }
2.2运行结果：
3.斗牛游戏：
import java.util.*; public class PokerPlay { public static void main(String[] args) { //定义一个ArrayList集合用来存放排盒 //分别用来给玩家和庄家的两副牌 ArrayList<String> array = new ArrayList<String>(); ArrayList<String> array1 = new ArrayList<String>(); //定义花色、点数数组 String[] color = {"♣", "♦", "♠", "♥"}; String[] numbers = {"2", "3", "4", "5", "6", "7", "8", "9", "10", "J", "Q", "K", "A"}; //封装组合成牌放入集合中 for (String s1 : color) { for (String s2 : numbers) { array.add(s1 + s2); } } //定义庄家的牌盒 String[] color1 = {"♣", "♦", "♠", "♥"}; String[] number1 = {"10", "J", "Q", "K",}; for (String s1 : color1) { for (String s2 : number1) { array1.add(s1 + s2); } } int count = 1;//定义局数 while (true) { int sum1 = 0, sum2 = 0, sum3 = 0; int sum4 = 0, sum5 = 0; //打乱牌的顺序 Collections.shuffle(array); Collections.shuffle(array1); //定义五个牌位 ArrayList<String> poker1 = new ArrayList<String>(); ArrayList<String> poker2 = new ArrayList<String>(); ArrayList<String> poker3 = new ArrayList<String>(); ArrayList<String> poker4 = new ArrayList<String>(); ArrayList<String> poker5 = new ArrayList<String>(); // 为了防止玩家崩溃，随机数给庄家无敌牌或普通牌 Random r=new Random(); int 换位=r.nextInt(100); //给庄家的无敌牌 for (int i=0;i<array1.size();i++){ String s1 = array1.get(i); if(sum5<5&&换位<50){ poker5.add(s1); sum5++; } } for (int i = 0; i < array.size(); i++) { String poker = array.get(i);//得到每张牌 if (sum1++ < 5) { poker1.add(poker); } else if (sum2++ < 5) { poker2.add(poker); } else if (sum3++ < 5) { poker3.add(poker); } else if (sum4++< 5) { poker4.add(poker); }//使庄家的牌正常，可以设置多少一个轮回 else if (sum5++<5) { poker5.add(poker); } } System.out.println("**************第" + (count++) + "局斗牛游戏开始:**************"); Scanner sc = new Scanner(System.in); System.out.print("庄家:"); String play5 = sc.nextLine(); System.out.print("第一位玩家:"); String play1 = sc.nextLine(); System.out.print("第二位玩家:"); String play2 = sc.nextLine(); System.out.print("第三位玩家:"); String play3 = sc.nextLine(); System.out.print("第四位玩家:"); String play4 = sc.nextLine(); System.out.println("-------买定离手--------"); lookPoker("庄家"+play5, poker5); lookPoker("玩家"+play1, poker1); lookPoker("玩家"+play2, poker2); lookPoker("玩家"+play3, poker3); lookPoker("玩家"+play4, poker4); System.out.println("-------游戏结束--------"); } } //定义一个看牌的动作 public static void lookPoker(String name, ArrayList<String > arrayList){ //遍历牌 System.out.print(name + "的牌:"); for (String poker : arrayList) { System.out.print(" " + poker); } System.out.println(); }}
其中 在用random，用if是控制庄家的牌
Random r=new Random(); int 换位=r.nextInt(100); //给庄家的无敌牌 for (int i=0;i<array1.size();i++){ String s1 = array1.get(i); if(sum5<5&&换位<50){ poker5.add(s1); sum5++; }
3.1运行结果：
