Java超详细教你写一个斗地主洗牌发牌系统

//准备牌
        HashMap<Integer,String> map=new HashMap<>();
        ArrayList<Integer> list=new ArrayList<>();
        map.put(1,"大王");
        map.put(2,"小王");
        list.add(1);
        list.add(2);

        String[] numbers={"2","A","K","Q","J","10","9","8","7","6","5","4","3"};
        String[] colors={"♠","♥","♦","♣"};

        int index=3;
        for (String number : numbers) {
            for (String color : colors) {
                map.put(index,number + color);
                list.add(index);
                index++;
            }
        }

	//洗牌
	Collections.shuffle(list);
	
	//发牌
	ArrayList<Integer> diPai=new ArrayList<>();
	ArrayList<Integer> player1=new ArrayList<>();
	ArrayList<Integer> player2=new ArrayList<>();
	ArrayList<Integer> player3=new ArrayList<>();
	
	for (int i = 0; i < list.size(); i++) {
	    if(i>=51){
	        diPai.add(list.get(i));
	    }else if(i%3==0){
	        player1.add(list.get(i));
	    }else if(i%3== 1){
	        player2.add(list.get(i));
	    }else {
	        player3.add(list.get(i));
	    }
	}
	//排序
    Collections.sort(diPai);
    Collections.sort(player1);
    Collections.sort(player2);
    Collections.sort(player3);

    //看牌
    look("周润发",player1,map);
    look("刘德华",player1,map);
    look("周星驰",player1,map);

  private static void look(String name, ArrayList<Integer> list, HashMap<Integer, String> map) {
        System.out.println(name+"：");
        for (Integer number : list) {
            System.out.print(map.get(number)+" ");
        }
        System.out.println();
    }
