实验三Java猜数字游戏开发课程：Java实验班级：201352 姓名：程涵学号：20135210成绩：指导教师：娄佳鹏实验⽇期：15.06.03实验密级：预习程度：实验时间：仪器组次：必修/选修：选修实验序号：3实验名称： Java猜数字游戏开发（姬梦馨、程涵⼩组）⼀、实验⽬的与要求：通过编写Java的应⽤系统综合实例——猜数字游戏，总结、回顾和实践⾯向对象的编程思想以及编程⽅法，并通过编写程序来掌握Java语⾔编程技巧，将学习到的知识融会贯通，同时提⾼调试程序的能⼒，养成良好的编程习惯，并增强对程序设计整体思路的把握。

⼆、设备与环境硬件：MacBookAir软件：JDK 1.8.0; eclipse三、实验内容（1）实验需求分析：1．玩家输⼊⼀个数字，数字的范围在1-100之间，系统获取随机数。

2．对玩家输⼊的数字进⾏判断⼤⼩，如果不是系统要求的数字，系统将提⽰您，您输⼊的不是数字请重新输⼊，给出提醒以便玩家进⼀步选择。

3. 玩家猜中时系统给出所⽤时间和游戏⽔平的判断，系统给出是否继续的提⽰及判断。

4.系统根据您猜数字的次数，⾃动计数.5. 直到⽤户猜到数字为⽌，提⽰信息是否继续猜数字，如果继续将进⼊下⼀次游戏，如果退出将退出游戏系统.（2）功能模块详细设计1.随机数的获取功能描述：玩家输⼊⼀个数字，数字的范围在1-100之间，系统获取随机数。

2 输⼊输出模块功能描述：对玩家输⼊的数字进⾏判断和提⽰。

如果玩家输⼊的不是系统要求的数字，系统将提⽰您，您输⼊的不是数字请重新输⼊.。

如果玩家输⼊的数字与随机⽣成数相⽐较，⽐随机⽣成数⼩.系统提⽰您，数字太⼩请您重新输⼊。

如果玩家输⼊的数字与随机⽣成数相⽐较，⽐随机⽣成数⼤.系统提⽰您，数字太⼤请您重新输⼊。

3 判断模块功能描述：系统给出对其⽔平的判断和是否继续的提⽰；对玩家要求判断执⾏。

4 ⾃动计数模块功能描述：系统根据您猜数字的次数，⾃动计数.5 结果输出模块功能描述：直到⽤户猜到数字为⽌，提⽰信息是否继续猜数字，如果继续将进⼊下⼀次游戏，如果退出将退出游戏系统.(3)代码如下图所⽰：代码：import java.util.InputMismatchException;import java.util.Scanner;public class Main {public static void main(String[] args) {// 产⽣⼀个随机数int number = (int) (Math.random() * 100) + 1;// 加⼊countint count = 0;// 在这⾥加⼊最⼤值，和最⼩值int max = 100;int min = 1;while (true) {// 键盘录⼊数据Scanner sc = new Scanner(System.in);System.out.println("欢迎进⼊“猜数字游戏”");System.out.println("请输⼊你猜得数字：(" + min + "~" + max + ")"); try {count++;int guessNumber = sc.nextInt();// 判断if (guessNumber > number) {max = guessNumber;System.out.println("猜⼤了");}else if (guessNumber < number) {min = guessNumber;System.out.println("猜⼩了");}else {System.out.println("恭喜你,只⽤了" + count + "次就猜中了！"); // 问是否继续System.out.println("请问还要继续吗？(yes)");sc = new Scanner(System.in);String str = sc.nextLine();if ("yes".equals(str)) {// 重写赋值随机数number = (int) (Math.random() * 100) + 1;count = 0;max = 100;min = 1;}else {break;}}}catch (InputMismatchException e) {System.out.println("你输⼊的数据有误");}}}}（3）.游戏运⾏结果截图四、实验结果及分析通过此次Java综合性实验，我对Java有了系统的了解。

通过选择猜数字游戏这个题目，可以让我掌握Java中的包和类，并且可以灵活的使用my eclipse软件。

同时更加深入的了解字符界面的编程过程。

使我更熟练的掌握Java程序框架的搭建和类的创建格式。

在分析阶段，要进行面向对象的需求分析、系统设计、画出相应的需求分析图、系统设计模型图，这些工作更能锻炼我的逻辑思维，更能培养我思考的全面性。

让我学会了多角度思考问题，对我以后的编程奠定了更好的基础。

一、猜数字小游戏简介系统随机产生任意一个1—100的自然数，玩家输入数字，若输入的数字比随机生成数小，系统将提示，数字太小请您重新输入；如果输入的数字比随机生成数大，系统将提示，数字太大请您重新输入；若输入的字符不是合法字符，系统将提示，您输入的数字不合法，请从新输入，游戏开始时，系统自动记录您猜数字的时间和次数，结束后显示游戏共花费的次数和时间及对游戏结果的评价。

二、用户需求分析设计一个猜数字游戏程序，要求具体如下特性：a.输入任意一个数字。

数字的要求是1—100的自然数即可。

b.系统对您输入的数字进行判断。

如果玩家输入的数字与计算机随机生成数相比较，输入的数字比随机生成数小.系统将提示您，数字太小请您重新输入。

如果玩家输入的数字与计算机随机生成数相比较，如果输入的数字比随机生成数大。

系统将提示您，数字太大请您重新输入。

使⽤JavaBean实现猜数字⼩游戏（Web实验）要求：游戏随机给出⼀个1—100（包括1和100）的数字，然后让你猜是什么数字。

游戏会提⽰太⼤或太⼩，从⽽缩⼩结果范围。

实例包含⼀个JavaBean（GessNumber.java）和两个JSP页⾯：guess.jsp,getNumber.jsp。

思路：使⽤ecplise,要通过javaBean实现,那么⾸先创建javaBean,然后再创建产⽣随机数的getNumber.jsp页⾯和可以交互对错的guess.jsp页⾯。

JavaBean:简单的说，JavaBean是遵循特殊规范的Java类。

按功能分，可以分为可视Bean和不可视两类。

可视Bean是在画⾯上可以显⽰的Bean，通过属性接⼝接收数据并显⽰在画⾯。

不可视Bean即JSP中时常使⽤的Bean，在程序的内部起作⽤，如⽤于求值、存储⽤户数据等。

[导读]1. 这是一个猜数字的游戏，通过使用JSP调用JavaBean2. 需要两个文件，number.jsp和NumberGuessBean.java3. 先看number.jsp代码：＜html＞＜jsp:useBean id=number class=NumberGuessBean scope=session /＞＜jsp:setProperty name=number property=* /＞＜%if(number.getNumGuesses()==0){%＞＜B＞Welcome to the Number Gu1. 这是一个猜数字的游戏，通过使用JSP调用JavaBean2. 需要两个文件，number.jsp和NumberGuessBean.java3. 先看number.jsp代码：＜html＞＜jsp:useBean id="number" class="NumberGuessBean" scope="session" /＞＜jsp:setProperty name="number" property="*" /＞＜%if(number.getNumGuesses()==0){%＞＜B＞Welcome to the Number Guess game.＜/B＞＜br＞＜B＞I'm thinking of a number between 1 and 100.＜/B＞＜br＞＜b＞What's your guess?＜/b＞＜form method=post＞＜input type=text name="guess"＞＜input type=submit value=submit＞＜/form＞＜%}else if(number.getSuccess()){%＞Congratulations!
