自动生成试卷java代码 java自动组卷系统

Java 将智能生成的试卷信息从数据库导出并生成word文档

直接在网上找个试卷模版，打开后另存为xml，重命名为***.jsp 在需要输出的地方使用%=user.name %输出，然后在末尾加这段代码：%@page contentType="application/msword; charset=UTF-8" %

注：xml格式的word文件中首行内容

?xml version="1.0" encoding="UTF-8" standalone="yes"?

必须保证在jsp文件的第一行，否则导出的word将无法打开，提示格式错误

Q1: 用java开发基于web的试卷自动生成系统，要可以导出word文档

你尽管放心，不会有大侠为你提供的，你这叫定制开发，得付费的！哈哈！

Q2: Java编写一个能够自动生成小朋友算术练习题目的程序。设计一个程序，要求能够随机生成每个题目。

 * Java编写一个能够自动生成小朋友算术练习题目的程序。设计一个程序，要求能够随机生成每个题目。

 * 编写一个能够自动生成小朋友算术练习题目的程序。设计一个程序，要求能够随机生成每个题目，并具有以下基本功能：

 * （1）要求题目以单项选择题及填空题两种形式出现。

 * （2）完成一题后自动判断答案是否正确，分别弹出不同的提示，并自动更新成下一题。

 * （3）单击“退出”时，汇总本次计算结果，共完成几题，正确率，并给出相应评语。确定后正式退出。
