分析

流程:

1.造一個(gè)牌盒

2.造牌

3.洗牌

4.發(fā)牌

5.看牌

程序分析:

1.創(chuàng)建一個(gè)ArrayList<String>集合對(duì)象

2.新建兩個(gè)數(shù)組(花色,點(diǎn)數(shù)),將兩個(gè)進(jìn)行拼接

3.用Collections.shuffle();

5.發(fā)牌

6.看牌

代碼如下:

public class PokerTest {
  public static void main(String[] args) {
//創(chuàng)建一個(gè)牌盒
    ArrayList<String> arrayList = new ArrayList<>();
    //裝牌
    /**
     * 黑桃A,....黑桃K
     * 紅桃A,....
     * 梅花A,....
     * 方塊A,....
     */
    //定義一個(gè)花色數(shù)組
    String[] colors = {"?", "?", "?", "?"};
    //定義一個(gè)點(diǎn)數(shù)數(shù)組
    String[] numbers = {"A", "2", "3", "4", "5", "6", "7", "8", "9", "10", "J", "K"};
    for (String color : colors) {
      for (String number : numbers) {
        arrayList.add(color.concat(number));
      }
    }
    arrayList.add("大王");
    arrayList.add("小王");
    //洗牌
    Collections.shuffle(arrayList);
    //發(fā)牌
    ArrayList<String> cmeizu = new ArrayList<>();
    ArrayList<String> lwy = new ArrayList<>();
    ArrayList<String> huangfeng = new ArrayList<>();
    ArrayList<String> diPai = new ArrayList<>();
    for (int x = 0; x < arrayList.size(); x++) {
      if (x >= arrayList.size() - 3) {
        diPai.add(arrayList.get(x));
      } else if (x % 3 == 0) {
        cmeizu.add(arrayList.get(x));
      } else if (x % 3 == 1) {
        lwy.add(arrayList.get(x));
      } else if (x % 3 == 2) {
        huangfeng.add(arrayList.get(x));
      }
    }
    System.out.println(arrayList);
    lookPoker("農(nóng)民1:", cmeizu);
    lookPoker("農(nóng)民2:", lwy);
    lookPoker("地主:", huangfeng);
    lookPoker("底牌:", diPai);

  }

  public static void lookPoker(String name, ArrayList<String> array) {
    System.out.println(name + "的牌是:");
    for (String s : array) {
      System.out.print(s + " ");
    }
    System.out.println();
  }
}

這種做法有一個(gè)問題就是沒有排序

所以第二種做法:

步驟:

1,創(chuàng)建一個(gè)HashMap<ArrayList<Integer>,String>集合

2.創(chuàng)建兩個(gè)數(shù)組String類型(花色,點(diǎn)數(shù)),然后拼接numbers.concat(colors)

3.洗牌

4.發(fā)牌

5.看牌

具體實(shí)現(xiàn)如下:

import java.util.ArrayList;

import java.util.Collections;


public class PokerDemo {
  public static void main(String[] args) {

//創(chuàng)建一個(gè)牌盒

    ArrayList<String> arrayList = new ArrayList<>();

    //裝牌

    /**
     * 黑桃A,....黑桃K
     * 紅桃A,....
     * 梅花A,....
     * 方塊A,....
     */
    //定義一個(gè)花色數(shù)組
    String[] colors = {"?", "?", "?", "?"};
    //定義一個(gè)點(diǎn)數(shù)數(shù)組
    String[] numbers = {"A", "2", "3", "4", "5", "6", "7", "8", "9", "10", "J", "K"};
    for (String color : colors) {
      for (String number : numbers) {
        arrayList.add(color.concat(number));
      }
    }
    arrayList.add("大王");
    arrayList.add("小王");
    //洗牌
    Collections.shuffle(arrayList);
    //發(fā)牌
    ArrayList<String> cmeizu = new ArrayList<>();

    ArrayList<String> lwy = new ArrayList<>();

    ArrayList<String> huangfeng = new ArrayList<>();

    ArrayList<String> diPai = new ArrayList<>();

    for (int x = 0; x < arrayList.size(); x++) {
      if (x >= arrayList.size() - 3) {
        diPai.add(arrayList.get(x));
      } else if (x % 3 == 0) {
        cmeizu.add(arrayList.get(x));
      } else if (x % 3 == 1) {
        lwy.add(arrayList.get(x));
      } else if (x % 3 == 2) {
        huangfeng.add(arrayList.get(x));
      }

    }
    System.out.println(arrayList);
    lookPoker("農(nóng)民1:", cmeizu);
    lookPoker("農(nóng)民2:", lwy);
    lookPoker("地主:", huangfeng);
    lookPoker("底牌:", diPai);
  }

  public static void lookPoker(String name, ArrayList<String> array) {
    System.out.println(name + "的牌是:");
    for (String s : array) {
      System.out.print(s + " ");
    }
    System.out.println();
  }
}
