JAVA实现日期选择控件.docx

1、JAVA实现日期选择控件JAVA实现日期选择控件实现效果如下所示：想自己写个小的记帐本,数据库那该没问题了,想想前台的布置的时候,突然想要有个日期选择的控件旧好了,我知道DELPHI里有的,不知道JAVA里有没有,百渡下,好象没有很成型的,还有的要收费的,找到了下面的程序,是嵌到Button里的,自己写了个测试程序,还行,界面还算可以,基本功能也基本实现,虽然有些地方不是很智能,有待改进.程序如下:import java.util.Date;import java.util.Calendar;import java.text.DateFormat;import java.text.Simple
