In this task, we will create books written by the earthly authors Mark Twain and Agatha Christie. Using the MarkTwainBook and AgathaChristieBook classes, naturally, which inherit Book. You need to implement all the abstract methods in these classes. And in the parent class, implement the getOutputByBookType method.

Really a tough task to me. It took to me two days of reading and debugging to see what happened inside. A really nice task to learn about "this", "super" and OOP. 👍

It should be noted that your constructor for the Mark Twain and the Agatha Christie classes should invoke the parent class constructor e.g. super("Mark Twain") and also initialize the title for the child class e.g. this.title = parameter. This really isn't clear in the description.
