Description

Only Submit the tasks 3 and 4 Kotlin code in online.cs.miu.edu under Assignments.
Upload only the Kotlin files
Note: Do not upload compressed file. No need to use GitHub for this homework. Because IntelliJ IDEA useful for Lesson 2 Homework only. From Lesson 3 onwards you are going to work with Android Studio only.

Choice Planet Relative gravity
1 Venus 0.78
2 Mars 0.39
3 Jupiter 2.65
4 Saturn 1.17
5 Uranus 1.05
6 Neptune 1.23

4. Practice OO Concepts (Class, Object, Getters and Setters, Inheritance, Override etc.,
a. Create a class Book with the fields title, author and price. Make a constructor which initialize all the fields. Add a behavior with read() and just print a message “Reading Paper book”.
b. Create a subclass EBook from Book, include additional attribute filetype as String. (ex: pdf, epub, kindle etc.,). Override read() method and print the message as “Read from Electronic Device”.
