Description: We have information about publications of two types: book and article, where each of them has number, title, author (first name, last name). The book has price, publisher and number of copies, the article has wage, magazine name, and number of pages. When entering the details of the publication the user must enter the full name of the author as one String but the system will divide it into first name and last name. Besides creating the constructors, getters, setters and toString we need to create a method for calculating the author income as follows: For the book its price*number of copies - 20% which goes to the publisher For the article it's 10% of the wage * the number of pages In the application you need to create a list of publications (books and articles) and let the user enter their data, you should use ArrayList not array. After entering details of books and articles, then must do the following: 1. Let the user enter the last name of an author and print out the details of all their publications either a book or an article. 2. Using a recursive method, find the total income for all authors. 3. Enter a publication number, find it then if it's a book print the publisher, if an article print the magazine name. 4. Print out the first and last name of any author who has an article with more than 20 pages. The grading scheme 1. Creating the classes with correct choices of inheritance 10 marks 2.
