What class is the date field?

in date class.I mean when user will click in the set date field a calender with current date will appear and user will select from the calender.but i dont know how to implement the calender.

What classes are you talking about?
What is the "set date field"?

Do you mean you want a data type, or do you mean a GUI component that the user can use to select a date?
