题目1.数据库相关
1.报文格式定义如下：20字符长的姓名+1字符长的性别+3字符长的年龄姓名长度不足20的右边补空格 性别中0表示男，1表示女年龄不足3字符的左边补0如：denny 0026这一段报文解析后表示姓名为denny性别为男，年龄为26数据库表结构如下：create table test( name varchar(20) primary key, sex varchar(1), age varchar(3));java一，写一个方法public String makePackage(String name, int sex, int age);由输入的姓名，性别，年龄返回对应的报文二、写一个方法public void parserPackage(String package);由输入的报文，解析后写入数据库表test中.sql从test中取出年龄大于16岁的前10条记录从test中取出给定name的记录的sex,age以及按年龄排的名次
题目2javascript相关页面如下
<html> <body> <input id="package" type = "text"/> <input type="button" onclick="parse()"/> <input id="name" type="text"/> <input id="sex" type="text"/> <input id="age" type="text"/> </body></html>
用javascript 实现方法parser() 当点击按钮的时候，按照报文格式解析id为package的文本域的内容，并将解析完的结果写入到相应的id的文本域里。题目3css相关用css给上面的button加上背景图片web请求页面如下：<html> <body> <form action = "testServer"> <input name = "package"type="text"/> <input type="submit"/> </form> </body></html>写一个servlet调用parsePackage方法将请求页面表单域中的package的值解析并写入数据库，将此servlet配置到tomcat中

答案
java答案如下：</p><pre code_snippet_id="376946" snippet_file_name="blog_20140604_2_2610834" name="code" class="javascript">import java.sql.Connection;import java.sql.DriverManager;import java.sql.SQLException;import java.sql.Statement;public class YuchengFacetoFace {//报文格式定义如下： //20字符长的姓名+1字符长的性别+3字符长的年龄 //姓名长度不足20的右边补空格 性别中0表示男，1表示女 //年龄不足3字符的左边补0 //如： //denny 0026 //这一段报文解析后表示姓名为denny性别为男，年龄为26public String makePackage(String name, int sex, int age){//输入的合法性校验未做String Result = "";int length = name.length();if (length < 20){int cutLength = 20 - length;for (int i = 0; i < cutLength; i++) {Result += " ";}Result += name;}Result += sex;//099的情况呢？if (age < 10) { Result = Result + 0 + 0 + age;}elseif (age < 100) {Result = Result + 0 + age;}else{Result += age;}return Result;}//由输入的报文，解析后写入数据库表test中.public void parserPackage(String Package){String name = Package.substring(0, 19);;int sex = Integer.parseInt(Package.substring(20, 20));int age = Integer.parseInt(Package.substring(21, 23));/* * insert into test values(name, sex, age); * select top 10 * from test where age < 16 * select * from test where name = name odered by age */}//连接MYSQL数据库并创建数据库和表public static void CreateDataBase() throws SQLException, ClassNotFoundException{ String driver = "com.mysql.jdbc.Driver"; Class.forName(driver);//加载mysql数据库，用Class.forName（"驱动名称"）进行加载//第二步，创建数据库连接，将数据库与当前文件连接起来，后面才可以对数据库进行操作//格式：String url = "jdbc:mysql://localhost:3306/Yuchengtech";//建立数据库连接地址Connection conn = DriverManager.getConnection(url, "root", "admin");//连接数据库Statement s = conn.createStatement();String SQL = "insert into test(name, sex,age) values(" +'"'+ "susheng" + '"' + ", 1, 25);";s.execute(SQL);}public static void main(String[] args) throws SQLException, ClassNotFoundException {//YuchengFacetoFace yff = new YuchengFacetoFace();//System.out.println(yff.makePackage("susheng", 0, 12));CreateDataBase();}}
二、js的代码答案
<html> <head> <script language="javascript"> function parse() { var content = document.getElementById("package").value; var name = content.substring(1,20).trim(); var sex = content.substring(20,21); var age = content.substring(21,24); document.getElementById("name").value = name; document.getElementById("sex").value = sex; document.getElementById("age").value = age; } </script> </head> <body> <input id="package" type = "text"/> <input type="button" onclick="parse()"/> <input id="name" type="text"/> <input id="sex" type="text"/> <input id="age" type="text"/> </body></html>
css很简单 有个background-image:url(a.jpg);
web的答案
package com.yuchengtech;import java.io.IOException;import java.io.PrintWriter;import javax.servlet.ServletException;import javax.servlet.http.HttpServlet;import javax.servlet.http.HttpServletRequest;import javax.servlet.http.HttpServletResponse;public class TestServer extends HttpServlet {/** * The doGet method of the servlet. <br> * * This method is called when a form has its tag value method equals to get. * * @param request the request send by the client to the server * @param response the response send by the server to the client * @throws ServletException if an error occurred * @throws IOException if an error occurred */public void doGet(HttpServletRequest request, HttpServletResponse response)throws ServletException, IOException {String Src = request.getParameter("package");YuchengFacetoFace yff = new YuchengFacetoFace();yff.parserPackage(Src);}/** * The doPost method of the servlet. <br> * * This method is called when a form has its tag value method equals to post. * * @param request the request send by the client to the server * @param response the response send by the server to the client * @throws ServletException if an error occurred * @throws IOException if an error occurred */public void doPost(HttpServletRequest request, HttpServletResponse response)throws ServletException, IOException {String Src = request.getParameter("package");YuchengFacetoFace yff = new YuchengFacetoFace();yff.parserPackage(Src);}}
