今天遇到一个很有意思的游戏–斗地主，那么下面就开始实现斗地主啦！！！

package Demo_YY;  public class PockerIndex {   public static void main(String[] args) {     start();   }    public static void start(){     String pocker[] = new String[54];     String colors[] = {"♠","♣","♥","♦"};     String nums[] = {"3","4","5","6","7","8","9","10","J","Q","K","A","2"};      int index = 0;     for (int i = 0; i < nums.length; i++){       for (int j = 0; j < colors.length; j++){         pocker[index++] = colors[j] + nums[i];       }     }  //    大小王🃏🂿     pocker[index++] ="\uD83C\uDCCF";     pocker[index] ="\uD83C\uDCBF"; //    看牌     for (int i = 0; i < pocker.length; i++){       System.out.print(pocker[i]+"\t");       if((i+1) % 4 == 0 )       {         System.out.println();       }     }    } } 

  int index = 0;     for (int i = 0; i < colors.length; i++){       for (int j = 0; j < nums.length; j++){         pocker[index++] = colors[i] + nums[j];       }     } 

修改了这里之后发现什么了呢？就是顺序不一样而已啦！

这里只是存储了54张牌，下面我们开始洗牌啦！

package Demo_YY;  public class PockerIndex {  public static void main(String[] args) {    start();  }   public static void start(){    String pocker[] = new String[54];    String colors[] = {"♠","♣","♥","♦"};    String nums[] = {"3","4","5","6","7","8","9","10","J","Q","K","A","2"};     int index = 0;    for (int i = 0; i < nums.length; i++){      for (int j = 0; j < colors.length; j++){        pocker[index++] = colors[j] + nums[i];      }    }  //    大小王🃏🂿    pocker[index++] ="\uD83C\uDCCF";    pocker[index] ="\uD83C\uDCBF";    System.out.println("\t\t\t看牌"); //    看牌    for (int i = 0; i < pocker.length; i++){      System.out.print(pocker[i]+"\t");      if((i+1) % 8 == 0 )      {        System.out.println();      }    }    System.out.println();    System.out.println(); //    洗牌    for(int i = 0; i < pocker.length; i++){      int index1 = (int)(Math.random()*pocker.length);      int index2 = (int)(Math.random()*pocker.length);      String temp = pocker[index1];      pocker[index1] = pocker[index2];      pocker[index2] = temp;    }    System.out.println("\t\t\t洗牌后\t\t");    for (int i = 0; i < pocker.length; i++){      System.out.print(pocker[i]+"\t");      if((i+1) % 8 == 0 )      {        System.out.println();      }    }    }   }
