Output: Handwritten program

----------------------------------------------------------------------------------
Write a program that can be used to generate a Gregorian calendar for a specified year.
INPUTS: year, day for January 1 of the year
OUTPUT: Calendar for the year such that monthly calendars are shown on the screen one at a time .
Notes:
You are NOT expected to use the Calendar and /or Date classes. You have to write the complete program
by utilizing only the primitive data types and the String class.
Take note that you have to determine if the input year is a leap year or not. There are 29 days for the month
of February of a leap year. Otherwise, February has 28 days. A year is a leap year if it is divisble by 4 but
not by 100 or if it is divisible by 400. For example, the yer 2003 is not a leap year; 2004 is a leap year.
1900 hundred is NOT a leap year becuase it is divisible by 100. 2000 is a leap year because it is dvisible by
400 although it is divisible by 100. Since the Gregorian calendar was adopted in 1582, validation of the
year entered must be done such that an error message is produced when the year entered is less than 1582.
