Build a new Book class(Book.java). This class will be a sub-class of Product. So it will inherit all the properties of Product(productId, description and price). Also add 4 new properties: title, author, publisher and isbn. A total of 7 properties. Create this class, make sure to add 2 constructors, all set and get methods, a display() method, and a toString method. Then use main to test out this class.

Main Code

Book b1;

b1 = new Book(k77, TextBook, 69.00, Intro to Java, Jones, APress, 9888771212);

b1.display(); //prints all 7 properties
