具有每日记账功能的简易日历程序

Question

java要求:编写具有图形用户界面(GUI)的日历组件显示日期和时间并进行适当的功能扩充。主要功能:
1、显示当月日历，当前日期、当前时间；2、可查询任意月以及任意年的日历；3、正常运行和退出程序。
4、每日具有记账功能，需要至少包含1)记账id；2)记账类型；2)支出费用；3)关键字(关键字写为一行，关键字数量不限，使用分号分割<需查阅使用>)
5、能够通过关键字查询某一种类型的记账记录。6、对当月记账类型的汇总；对特定关键字的记账汇总。
除Swing/AWT以外，可能是用到的类:日期类；String/StringBuffer;容器类；Math类，IO相关类。(要自己写，不能抄袭)
