SCAU大二上Java综合性实验

一、题目要求

实验内容：

1. 已经提供的原始数据：班级成绩单文件

该文件为文本文件，存储某个班的所有学生某门课程的成绩。

例如：2012级计算机科学与技术8班-面向对象程序设计.txt

文件中每行存储一个学生的成绩，包括：学号、姓名和成绩，中间用英文逗号分隔。

说明：学号和姓名是字符串，成绩使用整数。

例如“2012级计算机科学与技术8班-面向对象程序设计.txt”文件中存放该班学生面向对象程序设计的考试成绩。内容为：

201230740801,赵一,68

201230740802,钱二,82

201230740803,孙三,58

201230740804,李四,62

201230740805,冯五,73

……

2. 实验要求：

(1) 程序使用图形用户界面。

(2) 文件操作与数据统计功能

<1> 打开上面给出的文本文件，将其中的成绩数据加载到内存。

<2> 把内存中的成绩数据另存为格式相同的另一个文本文件。

<3> 把内存中的成绩数据另存为一个二进制的对象文件。

<4> 打开已经保存的二进制的对象文件，将其中的成绩数据加载到内存。

<5> 统计分析已经加载到内存的班级的成绩，包括：最高分、最低分、平均分、各成绩等级的人数和百分比。

说明：该部分界面参见图1，黄色注释框标出的是完成本部分功能需要的界面。

(3) 图形统计功

<1> 对加载到内存的成绩单进行“柱形图”分析

<2> 对加载到内存的成绩单进行“饼图”分析

说明：该部分界面参见图2，图1红注释框标出的是完成本部分功能需要的按钮。图形使用Java的Graphics对象绘制，不得使用第三方类库。

(4) 查询排序功能

<1> 在“查询输入框”输入“学号、姓名或成绩”的全部或部分，成绩列表中只显示包括输入数据的成绩项目。

<2> 点击表格的“列标题”，可以自动按该列排序，2次点击可以切换“升序”和“降序”。

说明：图1黑色注释框指出的是查询界面的位置。提示：JTabel的RowSorter。

提交要求：

二、功能实现方法

1.图形用户界面

运用了Swing 的组件类（JFrame,JButton,JLable等等）去完成了这个功能，使用了可视化编程的方法去完成了,然后使用监听器去触发事件。

2.文件操作与数据统计功能

所有选择文件操作的都使用JFileChooser去完成。

普通文件输入输出使用，Scanner , PrintWriter 实现。

而对象（二进制）文件即使用DataInputStream , DataOutputStream 来实现。

所有读入的数据存储在一个 ArrayList 里面。

3.图形统计功

使用Graphics 类制作圆，矩形，然后通过数据来调节矩形的高度，通过百分比分配圆的弧度来实现柱状图和饼状图的分析功能。

4.查询排序功能

使用JTable 来展现保存在ArrayList中的所有学生的数据。

利用 JTable 中的自动排序功能，还有滤器分别完成排序和查找功能。

学了4日的JAVA，写了2日的Java...使用可视化编程写的界面，主类代码坎长得一B，可读性甚差~~ 这样了！！

普通文件读写的编码上面还是有一点问题。我就默认了UTF-8算了。

下面是源程序的几个类
