Java basics-controls for handling date issues in Java

In a project R & D, you need to select the date and time controls. There are not many items available on the Internet and the quality is average,
So I had to do it myself. I referred to the DateChooser control for a file Jave on the Internet.

The current Code encapsulates the Date and Time Selection in a button component,
It should be easy to use and support Application and Applet
