Note, you should include an abstract method in animal that is defined in the child classes, and one abstract method in the interface that is implemented.

- Explain why you prefer interfaces over abstract classes.Java Programming Object-Oriented Programming In an abstract class, write a factory method for creating a category of object of your choice (aside from furniture). Also, write the class representing that category.b) Write the child classes that are necessary to create 3 different types of objects that belong to that categoryAbstract classes and interfaces may be used interchangeably to specify the behavior of objects.How do you know whether you need an interface or an abstract class?
- Object models, as well as the concepts of encapsulation and polymorphism, are inexorably intertwined.Implement the following hierarchy using C++ classes. 1. Shape: This should be an interface class that supports area() and display() functions. 2. Circle and Rectangle: Implement the area and display functions of Shape. 3. Quadrilateral: This class should be an abstract class. It may contain member variables for length and height. 4. Trapezoid: Should inherit length, height from Quadrilateral, and add 'side', represents the side parallel to 'length'. 5. Create appropriate .h/.cpp files with constructors and destructors (wherever needed). which 6-Both abstract classes and interfaces may be used to specify the behavior of common objects.Which factors should you examine when deciding between an interface and an abstract class?
- language: Java Class Inheritance with an abstract class Define a class Employee with the following fields: _name, _empId, _department, _position (_title), _yearlySalary, _fullTime (a boolean: true/false) , _month , _year (time of hire) Add constructor and properties Define an abstract method GetBiMonthlySalary() (if the employee is paid twice a month) Define an abstract method GetVacationTime() that returns the number of vacation time this employee would have based on time of hire Override the ToString() method to return a string that contains the information pertaining to an employee such as name, empId, department, and where full time or not. Define a class HourlyEmployee that inherits from Employee. This class should have 2 fields of its own: _hours (hours worked in half a month) and _wage (hourly wage) Provide necessary constructor, properties and methods Override the ToString() to also return the additional fields Gets 3 days of vacation after first year if the…PROGRAMMING LANGUAGE: JAVA SUBJECT: ADVANCED OOP WITH JAVA QUESTION NO 1: Make an abstract class named A1 with 2 abstract methods, then implement those methods in child class.Distinguish between implementing an interface and implementing a derived class.
- It is necessary for a subclass of an abstract class to implement all of the abstract methods that are defined for the parent class. Is there a mistake or is it accurate?Computer Science Object Oriented Analysis and Design. Look at the problem described below and describe how you would break it into objects, consider ways to use inheritance and composition. Describe for me how those objects make a system of objects that solves the problem. You may use UML or just write out a list of classes describing their properties and interface. You should also include a short description of how those objects work together. A local travel agent has built a business on using their knowledge of Europe to create custom trips for couples around Europe. For each client they create customized itineraries (a planned route or journey) and book all the travel and lodging accommodations for their high-end clients. For example they might build a custom vacation in Scotland where the client flies into St. Andrews and stays at a castle for 1 night then takes a bus to Pitlochry where they stay at a hotel for 3 nights then take a private plane to Braemar where they stay in a…Abstract classes and interfaces may both be used to accomplish the goal of defining the behavior of common objects.Which factors should you take into account when deciding whether to utilize an interface or an abstract class?
