用JAVA编程实现斗地主小游戏（建牌，发牌，选地主，排序）

主程序

public static void main(String[] args) {
		//牌
		List<String> pokes = new ArrayList<>();
		//颜色花色
		List<String> colors = new ArrayList<>();
		//数量
		List<String> nums = new ArrayList<>();

		colors.add("♥");
		colors.add("♠");
		colors.add("♦");
		colors.add("♣");
		nums.add("A");
		for (int i=2; i<=10; i++){
			nums.add(i+"");
		}
		nums.add("J");
		nums.add("Q");
		nums.add("K");
		for (String c:colors){
			for (String n:nums){
				String pai = c+n;
				pokes.add(pai);
			}
		}
		pokes.add("大王");
		pokes.add("小王");
//		System.out.println(pokes);
//		System.out.println(pokes.size());
		Collections.shuffle(pokes);
		System.out.println(pokes);

		//玩家
		//发牌，留三张
		ArrayList<String> smj = new ArrayList<>();
		ArrayList<String> whb = new ArrayList<>();
		ArrayList<String> zk = new ArrayList<>();
		ArrayList<String> bottom = new ArrayList<>();
		for (int i = 0; i < pokes.size(); i++) {
			String pai = pokes.get(i);
			if(i>=51){
				bottom.add(pai);
			}
			else{
				if (i%3==0){
					smj.add(pai);
				}
				else if(i%3==1){
					whb.add(pai);
				}
				else {
					zk.add(pai);
				}
			}
		}
		System.out.println("底牌"+bottom);
		System.out.println("smj"+smj);
		System.out.println("whb"+whb);
		System.out.println("zk"+zk);

		//选择地主：
		System.out.println("请输入地主：");
		Scanner scanner = new Scanner(System.in);
		String dz = scanner.nextLine();
		for (int i = 0; i < bottom.size(); i++) {
			String pai = bottom.get(i);
			if (dz.equals("smj")){
				smj.add(pai);
			}
			else if(dz.equals("whb")){
				whb.add(pai);
			}
			else {
				zk.add(pai);
			}
		}
		//清空底牌
		bottom = null;
		System.out.println("底牌"+bottom);
		System.out.println("smj"+smj);
		System.out.println("whb"+whb);
		System.out.println("zk"+zk);

		//排序
		//按大王小王2KQJ1098765432A
		System.out.println("调整手牌");
		smj=paix(smj);
		whb=paix(whb);
		zk=paix(zk);
		System.out.println("smj"+smj);
		System.out.println("whb"+whb);
		System.out.println("zk"+zk);

排序算法

思想为把该扑克牌数组复制一个为数字类型的数组，对数组进行排序，同时更改扑克牌数组。

public class sort {

	private static <E> void swap(List<E> list, int index1, int index2) {   //数组元素交换位置
		E e=list.get(index1);
		list.set(index1, list.get(index2));
		list.set(index2, e);
	}
	static ArrayList<String> paix(ArrayList<String> x){    //纸牌有序化
		ArrayList<Integer> xyz=new ArrayList<>();
		int f=-1;
//复制一个数字类型的数组
		for (int i = 0; i < x.size(); i++) {
			if(x.get(i).equals("大王"))
				f=172;
			else if(x.get(i).equals("小王"))
				f=171;
			else {
				if (x.get(i).substring(1).equals("A"))
					f = 140;
				else if (x.get(i).substring(1).equals("2"))
					f = 150;
				else if (x.get(i).substring(1).equals("J"))
					f = 110;
				else if (x.get(i).substring(1).equals("Q"))
					f = 120;
				else if (x.get(i).substring(1).equals("K"))
					f = 130;
				else f= Integer.parseInt(x.get(i).substring(1)) * 10;

				if(x.get(i).substring(0,1).equals("♥")){
					f+=4;
				}else if(x.get(i).substring(0,1).equals("♦")){
					f+=3;
				}else if(x.get(i).substring(0,1).equals("♠")){
					f+=2;
				}else if(x.get(i).substring(0,1).equals("♣")){
					f+=1;
				}
			}
			xyz.add(f);
		}

//        System.out.println(xyz);

		for (int i = x.size(); i > 1; i--) {
			for (int j = 0; j < i-1; j++) {
				if(xyz.get(j) < xyz.get(j+1)){
					swap(xyz,j,j+1);
					swap(x,j,j+1);
				}
			}
		}

		return x;
	}
