DayofWeek class:

WeekDay class:

Now modify the two classes a) DayOfWeekDisplay i. The DayOfWeekDisplay class should use Number Display to circle thru the days of the week and to display them as Monday" ... "Sunday". ii. In the constructor you need to properly initialize Number Display and to populate the HashMap. Implement the methods nextDay and getDay. b) WeekDisplay i. The WeekDisplay class should use Number Display to circle thru the weeks of the year (and to display them as "01"... "52". ii. Implement the constructor. Implement the methods nextWeek and calculate String. Now modify the two classes a) DayOfWeekDisplay i.
