Problem Name:
In this HackerRank Functions in Java programming problem solution,
The Calendar class is an abstract class that provides methods for converting between a specific instant in time and a set of calendar fields such as YEAR, MONTH, DAY_OF_MONTH, HOUR, and so on, and for manipulating the calendar fields, such as getting the date of the next week.

Example
month = 8
day = 14
year = 2017
The method should return MONDAY as the day on that date.
