- 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).Abstraction is the basis for good Object-Oriented design that is modular, reusable, and maintainable. Interfaces and Abstract classes are two mechanisms in Java that provide high-level abstractions. An interface or abstract class is something which is not concrete, something which is incomplete. what do you think is meant by “Programming to an interface”? What are some differences between Abstract Classes and Interfaces? Provide a simple example application with an interface definition and a class which implements the interface.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
- Computer Science we have learned about interfaces knowledge. Interfaces are preferred to define a common supertype for unrelated classes. Interfaces are more flexible than classes. You may design and consider the Animal class , and then you may suppose the how To Eat method is defined in the Animal class.Describe a benefit from requiring class to implement an interface.Abstraction is the basis for good Object-Oriented design that is modular, reusable, and maintainable. Interfaces and Abstract classes are two mechanisms in Java that provide high-level abstractions. An interface or abstract class is something which is not concrete, something which is incomplete. For this discussion, what do you think is meant by “Programming to an interface”? What are some differences between Abstract Classes and Interfaces? Provide a simple example application with an interface definition and a class which implements the interface.
- Explain why you think interfaces are better than abstract classes in your opinion.Use java programming language 1.1 Create a Student Object project. Create a Student class and use the provided UML diagram to code the instance fields, constructors and methods. Note: The module mark is the average of the participation mark and the examination mark - calculate this using the calcModuleMark() method. The determineStNumber() method should compile a student number with the first 3 letters of the student's name, a '#' symbol, and a 3-digit randomly generated number (make use of a for-loop to concatenate these 3-digits). The stNumber data field should be set in the constructor by calling the determineStNumber() method. The toString() method must compile a string to display the student number, participation mark, examination mark, and module mark, formatted in table format. Student number PMark EMark MMark Mar#9186 81 64 72.00 1.2 Create a testStudents class. Do the following: -Write a static method called display() which receives…Use java programming properties to write all the necessary classes and/or interfaces for a solution to the problem. Focus on class structure and interaction. You may implement your solution however you wish, but you will be graded on the appropriateness of your solution to the requirements. Note the use of capitalization and parentheses for clarification. You may use whatever constructors or additional methods you wish. Define a structure that can represent Animals. Animals have two behaviors; they can speak() and they can move(). By default, when an animal moves, the text ”This animal moves forward” is displayed. By default, when an animal speaks, the text ”This animal speaks” is displayed. A general Animal should not be able to be instantiated. Define two classes, Goose and Lynx, that are Animals. Both Goose and Lynx behave such that where “Animals” is displayed in speak() or move(), “goose” or “lynx” is displayed by the appropriate classes. Finally, any instance of Goose can fly(),…
- Classes at the abstract level and interfaces at the implementation level may both be used to describe the same kinds of behavior in different objects.What criteria should you use to choose between using an interface and an abstract class?Make sure you know the difference between an abstract class and an interface and constructors.Design and implement a class called Bug, which represents a bug moving along a horizontal wire. The bug can only move for one unit of distance at a time, in the direction it is facing. The bug can also turn to reverse direction. For your design, create a UML Class diagram . Note that you need to include the constructor in the methods section if you code a constructor. Bug will require a toString method to return the current position and which direction the bug is facing to the driver so it can be output Write an interactive test driver that instantiates a Bug, then allows the user to manipulate it with simple commands like Output (to see the position and direction), Move, Turn, Exit ... single letters work just fine. All output should be via the driver not methods within Bug. You should use this driver to create screenshot exhibits for a number of scenarios (e.g., output original position, move a few times, output, move a few more times, output, turn, output, move, output, etc.).…
