猜数目字小游戏 _Web前端

猜数字小游戏

刚刚帮别人做了一个大作业，是写一个猜数字的MVC基本架构的小游戏。

时间：2小时。
难易程度：中
难点：随机数的产生次数，以及技术功能的实现。

下面是代码：
shuzi.jsp

<%@ page language="java" pageEncoding="UTF-8"
	contentType="text/html;charset=UTF-8"%>
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core"%>
<html>
	<head>
		<title>猜数字</title>
	</head>
	<body>
		<form method="post"
			action="${pageContext.request.contextPath}/Control">
			<br>
			<br>
			<br>
			<br>
			????????????????????????????????????????????????????
			?
			<strong><font size="5">猜数字(请输入100以内的整数) 
			</strong>
			<br>
			${result }
			<table align="center" width="300" height="50" border="1">
				<tr>
					<td align="center">
						?请输入数字:
					</td>
					<td>
						?
						<input type="text" name="text1">
					</td>
				</tr>
				<tr>
					<td align="center" colspan="2">
						<input type="submit" value="提交" name="button1">
					</td>
				</tr>
			</table>
		</form>
		<%
		request.setCharacterEncoding("UTF-8");
		%>
		<c:choose>
			<c:when test="${count>0}">您猜了${count }次</c:when>
		</c:choose>
		</font>

	</body>
</html>

?fm.action包

Control.java

package fm.action;

import java.io.IOException;
import java.io.PrintWriter;
import java.util.*;

import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import javax.servlet.http.HttpSession;

import fm.service.caishu;
import fm.service.random;

public class Control extends HttpServlet {

	int count = 0;

	int random = 0;

	int num;

	String result = null;

	random r = new random();

	caishu c = new caishu();

	public void doGet(HttpServletRequest request, HttpServletResponse response)
			throws ServletException, IOException {

		response.setContentType("text/html;charset=utf-8");
		PrintWriter out = response.getWriter();

		request.setCharacterEncoding("UTF-8");
		doPost(request, response);
	}

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

		response.setContentType("text/html;charset=utf-8");
		PrintWriter out = response.getWriter();

		request.setCharacterEncoding("UTF-8");

		int cai = Integer.parseInt(request.getParameter("text1"));

		// 只生成一个随机数
		if (random == 0) {
			num = r.randomNum();
			System.out.println(num);
			random++;
		}

		result = c.caishu(cai, num,count);
		++count;
		request.setAttribute("count", count);
		request.setAttribute("result", result);
		
		
		request.getRequestDispatcher("./shuzi.jsp").forward(request, response);

	}

}

fm.service包

caishu.java

package fm.service;

import java.util.*;
import java.io.*;

public class caishu {

	String result;	

	public String caishu(int cai, int a, int b) {

		if (cai > a) {
			result = "请输入小点的数";
			return result;
		} else if (cai < a) {
			result = "请输入大点的数";
			return result;
		} else {
			if (b <=2) {
				result = "猜对了，你真是个天才！";
				return result;
				
			} else if (b < 6) {
				result = "还将就，你过关了！";
				return result;
			} else if (b < 8 ) {
				result = "但是你还……真笨！";
				return result;
			} else {
				result = "你和猪没有两样了！";
				return result;
			}
		}
		
	}
}

?random.java

package fm.service;

import java.util.*;
import java.io.*;

public class random {
		public int randomNum() {
			Random a=new Random(); 
			int num=a.nextInt(100); 
			
			return num;
		}
	}

完毕。
