Answer 1

package Tester;

import java.io.IOException;
import java.util.Random;

import javax.servlet.ServletException;
import javax.servlet.annotation.WebServlet;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

@WebServlet("/剪刀石头布.jsp")
public class Tester01 extends HttpServlet {

    protected void doGet(HttpServletRequest request, HttpServletResponse response)
            throws ServletException, IOException {
        request.setCharacterEncoding("utf-8");

        String d = "";
        // 这里接收到你前台选择的石头还是剪刀还是石头
        String s = request.getParameter("s");

        Random random = new Random();
        // 这里随机出1，2，3
        int res = random.nextInt(4);
        // 这里判断电脑出的石头还是剪刀还是石头
        if (res == 1) {
            d = "石头";
        }
        if (res == 2) {
            d = "剪刀";

        }
        if (res == 3) {
            d = "石头";

        }
        if (d=="石头"&s=="剪刀") {
            
            request.setAttribute("result", "电脑出的是石头，你是剪刀电脑胜");
//            剩下的判断自己写，前台接收下result展示就可以
        }

    }

    protected void doPost(HttpServletRequest request, HttpServletResponse response)
            throws ServletException, IOException {

    }

}

拿去看吧，望采纳
