Step by step
Solved in 3 steps
- The ability to create classes with more specific attributes and methods that share the properties and methods of existing classes is referred to as: Abstraction Polymorphism Typecasting InheritanceSo why is it important for a class to have its own destructor?Static class members are exactly what they sound like. When and how can they be used?
- Do classes and objects interact in any particular way?In java language please explain these three class design guidelines at least one page per guideline you code use some examples to explain. Encapsulation: Instance vs Static: Inheritance vs Aggregation:Library Information System Design and Testing Library Item Class Design and TestingDesign a class that holds the Library Item Information, with item name, author, publisher. Write appropriate accessor and mutator methods. Also, write a tester program(Console and GUI Program) that creates three instances/objects of the Library Items class. Extending Library Item Class Library and Book Classes: Extend the Library Item class in (1) with a Book class with data attributes for a book’s title, author, publisher and an additional attributes as number of pages, and a Boolean data attribute indicating whether there is both hard copy as well as eBook version of the book. Demonstrate Book Class in a Tester Program (Console and GUI Program) with an object of Book class.
- Differentiate between abstract and concrete classes. Give examples from the scenario aboveExplain how final classes, methods, and parameters workC# How to call a base class constructor from a derived class constructor, also how to call another constructor from one constructor in the same class? Give example.
