public class
Date

extends Object
A wrapper for a date. This class lets you manipulate
dates in a system independent way. To print today's
date use:
Date d = new Date();
System.out.println("today = " + d);
To find out what day I was born:
Date d = new Date(1963, 0, 16);
System.out.println("Day of the week: " + d.day());
