Be sure, the class should have a property to hold the “upper bound” value. 4.

Course Title: Modern Programming Language Please Java Language Code Question : Design an abstract class GeometricObject. GeometricObject must ensure that its children must implement calcArea() method. Design Rectangle18-ARID-2891 and CircleM.JibranAkram Classes as children of GeometricObject class with overridden toString() method to return “Rectangle with w Width and h Height is drawn” OR “Circle with r Radius is drawn”. The attributes of Rectangle are length, width. The attribute of Circle is radius Hint: Area of circle=πr2 , Area of rectangle= width*length

The class has a non-abstract method add(T element) which adds the not-null element in the storage if the element is not already present. Create a class MyStorage which is a subclass of Storage.

Design and implement a Java class named Book with two data members: title and price. The class should have suitable constructors, get/set methods, and the toString method. Design and implement another Java class named BookShelf which has an ArrayList data member named bookList to store books. The class should have suitable constructors, get/set methods, and the toString method, as well as methods for people to add a book (prototype: addBook(Book book)), remove a book (prototype: removeBook(Book book)), and search for a book (prototype: findBook(Book book)). Test the two classes by creating a Bookshelf object and five Book objects. Add the books to the bookshelf. Display the contents of the bookshelf. Test the removeBook and findBook methods as well. Take screenshots of your tests and submit them with your Java code (not the whole project)
