Create an interface that shall have 2 methods and one string type attribute, also create an implementation class of the interface that shall define both methods (you can print YOUR favorite quote in each method body).
Step by step
Solved in 2 steps
- Create an interface that shall have 2 methods and one string type attribute, also create an implementation class of the interface that shall define both methodsWhen a class implements an interface with default methods and overrides them, the class inherits the default methods’ implementations. An interface’s designer can now evolve an interface by adding new default and static methods without breaking existing code that implements the interface. State whether the statement is true or false. If false, explain why.1. We want to create an interface to represent pets. What are some of the methods that will be in our interface? 2. Take one of the methods you listed above. Defend how it fits the criteria necessary for it to be used in an interface and not in an inherited class. 3. Write out what this interface would look like in Java.
- A library wants to manage its collection of books and authors more efficiently. They would like to create a Python program to help with this task. The following requirements need to be implemented: Create an Author class with the attributes: name, dob (date of birth), and nationality. The class should have a __str__ method to represent the author in a user-friendly format. Create a Book class with the following attributes: title, author (an instance of the Author class), publication_date, and price. Also, include a class variable all_books that keeps a list of all book instances created.The Book class should have: A __str__ method to represent the book in a user-friendly format. A __eq__ method to compare two books. Two books are considered the same if they have the same title and author. A __lt__ method to compare two books based on their publication dates. A class method get_all_books that returns a list of all books in the library. A static method most_expensive_book that takes…An interface can have : instance variables. only method headings without implementation. some methods with implementation. only one constructor.Write the class basics for an address class. Each class object should have its own street address, city, state and zip code. Be sure to include all the basic methods for this class.
- B elow for each class you find a UML and description of the public interface. Implementing the public interface as described is madatory. There's freedom on how to implement these classes.The private properties and private methods are under your control.. There are multiple ways of implementing all these classes. Feel free to add private properties and methods. For each object, it's mandatory to create a header file (.h), implementation file (.cpp) and a driver. Blank files are included. The header should have the class definition in it. The implementation file should contain the implementations of the methods laid out in the header fine. And finally the Driver should test/demonstrate all the features of the class. It's best to develop the driver as the class is being written. Check each section to see if there are added additional requirements for the driver. Two test suites are included so that work can be checked. It's important to implement the drivers to test and demonstrate…Why is it necessary to implement all of the methods defined by an interface?To implement an interface, a concrete class must implement AT LEAST ONE method headings listed in the definition of the interface. False. True.
