傷城~ 2024-03-26 07:24 6阅读 0赞

## 开发环境 ##

开发语言为Java，开发环境Eclipse或者IDEA都可以。数据库采用：MySQL。运行主程序，或者执行打开JAR文件即可以运行本程序。

## 系统框架 ##

利用JDK自带的SWING框架开发，不需要安装第三方JAR包。MySQL数据库，纯窗体模式，直接运行Main文件即可以

## 主要功能 ##

### **运行方法** ###

1 运行Main.java文件

2 程序出现在线考试系统登陆的面板

### 主要模块 ###

本次分享的为Java编写的窗体版本程序--在线考试系统，其主要目的是能对大学生在日常学习过程的知识进行有效的测试，通过系统了解大学生对课程知识的掌握程度，以便老师更好的有针对性的进行教学调整。其主要功能如下：

1 用户通过用户名和密码，登陆到在线考试系统中。同时也可以点退出按钮，退出在线考试系统

2 核对考生信息：学生在成功登陆到考试系统后，会弹出学号、姓名、专业、学院等信息，点击核对无误按钮后进入系统考试。

3 参与在线考试：学生点击在线考试按钮，开始考试。考试的过程从逐个题目开始作答，每个题目有对应的分数，答对获取相应的分数；打错该题得0分。答完所有题目后，点击交卷，完成本次考试。

4 查看考试成绩：学生点击主界面上得查看成绩，可以查看到本次考试得成绩和错题信息。

5 退出系统。学生点击退出按钮，退出整个应用程序。

6 老师可以对学生信息新增、修改、删除等操作。只有在系统中存在的考生，才能登陆到系统进行考试。

这个项目涵盖了java 窗体编程的各种知识，包括UI界面设计、时间处理、数据库操作、事件处理操作等。通过这个项目能快速提升java 窗体编程，是非常好一个有价值的的项目。代码可以直接运行，没有任何bug。
