思路

• 模拟斗地主洗牌和发牌

分析：
A:创建一个牌盒(ArrayLast)
B:装牌
C:洗牌
D:发牌
E:看牌

具体实现如下：

• A：创建一个牌盒
• B：装牌

 //创建花色数组
        String [] colors = {"♠", "♥", "♣", "♦"};
        //创建点数数组
        String [] numbers={"A","2","3","4","5","6","7","8","9","10","J","Q","K"};
        //创建一个牌盒
        ArrayList<String> arrayList  = new ArrayList<>();
        //将牌存入牌盒
        for (int i = 0; i <colors.length ; i++) {
            for (int j = 0; j <numbers.length ; j++) {
                arrayList.add(colors[i].concat(numbers[j]));
            }
        }
        arrayList.add("大王");
        arrayList.add("小王");

• C:洗牌

 //洗牌
        Collections.shuffle(arrayList);
        //System.out.println(arrayList);//呈现洗牌结果

• D:发牌

 //发牌
        ArrayList<String> John = new ArrayList<>();
        ArrayList<String> Sunny = new ArrayList<>();
        ArrayList<String> Tina = new ArrayList<>();
        ArrayList<String> LastPoker = new ArrayList<>();

        for (int x=0 ; x<arrayList.size();x++) {
                if(x>=(arrayList.size()-3)){
                    LastPoker.add(arrayList.get(x));
                }else if (x%3==0){
                    John.add(arrayList.get(x));
                }else if (x%3==1){
                    Sunny.add(arrayList.get(x));
                }else if (x%3==2){
                    Tina.add(arrayList.get(x));
                }
        }

• E:看牌(main中直接调用lookPoker方法)

//看牌方法
    public  static void lookPoker(String name ,ArrayList<String> list){
        System.out.print(name+" 的牌是: ");

        for (String string:list) {
                System.out.print(string+" ");
        }
        System.out.println();
    }
