Java Swing简单样例

     大学时候Java 学的很简单，当时玩的也多，学了就忘。额外买的java书看了几章就不看了，想想真是惭愧。最近由于实验室需要对于别人的东西做一点简单测试，我也就花了1天重新写了一个简单的Jframe界面。

   非常非常简单，本来都不好意思放上来，不过想着一点是一点，大学没不好好学习靠着以前的底子写一点简单东西

    1.JFileChooser选择路径在JTextField上展示

    2.数据浏览功能,txt数据用一个新的frame展示出来

    3.bean结构数据降序排列，计算时间

     4.将文件输出保存到当前工程文件夹下,按照文件名_type_日期(win下是\r\n换行、日期中符号  :  不能在文件名中出现)

需要排序的bean：

public class Store {private String str1;private String str2;private double rs;public String getStr1() {return str1;}public void setStr1(String str1) {this.str1 = str1;}public String getStr2() {return str2;}public void setStr2(String str2) {this.str2 = str2;}public double getRs() {return rs;}public void setRs(double rs) {this.rs = rs;}}

主函数所在类：
