As part of your first task, your supervisor requests you to aid with the development of a bank ticketing system that ensures the first time and already admitted customers are served according to a predefined preference as shown below. Write an algorithm that would ensure customers can be awarded tickets and served based on the type of service requested. Ensure you clearly mention all abstract data structures that the algorithm would use.

Which of the following situations described is a good situation to use an abstract class, and where it would be better to use than either a concrete class or an interface?

When some methods in the class are abstract and some are concrete, and some variables in the class need to be private, while other variables need to be public

When the inheriting class is closely related to the abstract class, such as with an "is-a" relationship

When the objects instantiated from the abstract class hierarchy need to be grouped together

When the class will have both concrete and abstract methods

All of the above are reasons to use an abstract class over a concrete class or an interface

A Java abstract class is a class that can't be instantiated. That means you cannot create new instances of an abstract class. It works as a base for subclasses. You should learn about Java Inheritance before attempting this challenge.


1. Java Abstract Class (2 pts) () • A Java abstract class is a class that can't be instantiated. That means you cannot create new instances of an abstract class. It works as a base for subclasses. You should learn about Java Inheritance before attempting this challenge.

• Following is an example of abstract class:

abstract class Book{

String title;

abstract void setTitle(String s);

String getTitle(){

return title;

}

}

If you try to create an instance of this class like the following line you will get an error:

Book new_novel=new Book();

• You have to create another class that extends the abstract class. Then you can create an instance of the new class. Notice that setTitle method is abstract too and has no body. That means you must implement the body of that method in the child class. In the editor, we have provided the abstract Book class and a Main class. In the Main class, we created an instance of a class called MyBook. Your task is to write just the MyBook class. Your class mustn't be public

. • Sample Input A tale of two cities

• Sample Output The title is: A tale of two cities

+ import java.util.*; abstract class Book{

String title;

abstract void setTitle(String s);

String getTitle(){

return title;

}

}

//Write MyBook class here public class Main{

public static void main(String []args){

//Book new_novel=new Book(); This line prHMain.java:25: error: Book is abstract; cannot be instantiated Scanner sc=new Scanner(System.in);

String title=sc.nextLine();

MyBook new_novel=new MyBook();

new_novel.setTitle(title);

System.out.println("The title is: "+new_novel.getTitle());

sc.close();

}

}
