Java Date and Time Hacker Rank solution
Java Date and Time Hacker Rank 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.
You are given a date. You just need to write the method, getDay,
which returns the day on that date. To simplify your task, we have provided a
portion of the code in the editor.
For example, if you are given the date August 14th 2017, the method
should return MONDAY as the day on that
date.
