Write a Java program to determining the day number (1 to 366) in a year for a date
that is provided as input data. As an example, January 1, 2012 is day 1.
December 31, 2011 is day 365. December 31, 2012 is day 366 because 2012 is a leap
year. A year is a leap year if it is divisible by four, except that any year
divisible by 100 is a leap year only if it is also divisible by 400. Your program
should accept the month, day, and year as integers.
