- dayType Class We will be working on a project that designs a class calendarType, so that a client program can use this class to print a calendar for any month starting Jan 1. 1900. An example of the calendar for September 2019 is: September 2019 Sun Mon Tue Wed Thu Fri Sat 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 We will develop several classes which will work together to create a calendar. The first of these classes is called dayType which will manipulate a day of the week. The class dayType will store a day, such as Sun for Sunday. The class should be able to perform the following operations on an object of type dayType: a. Set the day. b. Print the day. c. Return the day. d. Return the next day. e.…•Person Class: Person class has attributes: String name, address and int age. Write setperson() function to set values and getPerson() to Print attributes.
