Day 13: Abstract Classes - HackerRank 30 days of code solution
Objective Today, we're taking what we learned yesterday about I nheritance and extending it to Abstract classes. Because this is a very specific Object-Oriented concept, submissions are limited to the few languages that use this construct. Task Given a Book class and a Solution class, write a MyBook class that does the following: Inherits from Book Has a parameterized constructor taking these parameters: string string int Implements the Book class' abstract display() method so it prints these lines: , a space, and then the current instance's . , a space, and then the current instance's . , a space, and then the current instance's . Note: Because these classes are being written in the same file, you must not use an access modifier (e.g.: ) when declaring MyBook or your code will not execute. Input Form...
