这是核心算法

package com.veechin.java.test;

import java.util.ArrayList;
import java.util.Arrays;
import java.util.Collections;
import java.util.Comparator;
import java.util.List;
import java.util.SortedSet;
import java.util.TreeSet;

import com.veechin.java.util.Card;

public class test {
 public static void main(String arg[]){
  Card cards[]=new Card[52];
  String type[]={"红桃","黑桃","方片","梅花"};
  //初始化牌类
  for(int i=0;i<4;i++)
   for(int j=0;j<13;j++){
    cards[i*13+j]=new Card(j+1,type[i]);
   }
  //转变成集合
  ArrayList cardset=new ArrayList(Arrays.asList(cards));
     //洗牌
  Collections.shuffle(cardset);
     //发牌
  List player_one= cardset.subList(0, 13);
  List player_two= cardset.subList(13, 26);
  List player_three= cardset.subList(26, 39);
  List player_four= cardset.subList(39, 52);
  
  System.out.println("Player_One的牌");
  //排牌
  SortedSet player_one_sorted=new TreeSet(new Comparator() {

   public int compare(Card c1, Card c2) {
    return c1.compareTo(c2);
   }
  });
  player_one_sorted.addAll(player_one);
  for(Card temp:player_one_sorted){
   temp.getCardInfor();
  }
  System.out.println("Player_Two的牌");
  //排牌
  SortedSet player_two_sorted=new TreeSet(new Comparator() {

   public int compare(Card c1, Card c2) {
    return c1.compareTo(c2);
   }
  });
  player_two_sorted.addAll(player_two);
  for(Card temp:player_two_sorted){
   temp.getCardInfor();
  }
  
  System.out.println("Player_Three的牌");
  //排牌
  SortedSet player_three_sorted=new TreeSet(new Comparator() {

   public int compare(Card c1, Card c2) {
    return c1.compareTo(c2);
   }
  });
  player_three_sorted.addAll(player_three);
  for(Card temp:player_three_sorted){
   temp.getCardInfor();
  }
  
  System.out.println("Player_Four的牌");
  //排牌
  SortedSet player_four_sorted=new TreeSet(new Comparator() {

   public int compare(Card c1, Card c2) {
    return c1.compareTo(c2);
   }
  });
  player_four_sorted.addAll(player_four);
  for(Card temp:player_four_sorted){
   temp.getCardInfor();
  }
  
  
 }
}

 

下面是牌类：

package com.veechin.java.util;

public class Card implements Comparable{
 private int Size;
 private String Type;
 public Card(int size,String type){
  this.Size=size;
  this.Type=type;
 }
 public void getCardInfor(){
  System.out.println("Size: "+Size+"  Type: "+Type);
 }
 public int compareTo(Card other) {

  if(this.Size-other.Size==0){
   return 1;
  }
  return this.Size-other.Size;
 }
}

 

//运行结果如下：

 

 

当然如果想作游戏的话还须要修改添加进去大小王.
