In the class Office Hour Schedule, implement the following methods (documentation for each method is provided in the code). a) printisinOn(String day) b) isAvailableFor(String instructor, int minutes) Add a method (call it findinstructorsOnAfter) to Office HourSchedule that takes two parameters - campus and hour -- and returns a String containing the names of all instructors who offer an office hour on given campus that starts not before hour. You should exclude duplicate names (if an instructor offers multiple office hours). The string should start with "Instructors who are available on campus after hour.00 are: In the class Office Hour Schedule, implement the following methods (documentation for each method is provided in the code). a) printisinOn(String day) b) isAvailableFor(String instructor, int minutes) Add a method (call it findinstructorsOnAfter) to Office HourSchedule that takes two parameters - campus and hour -- and returns a String containing the names of all instructors who offer an office hour on given campus that starts not before hour.
