- Define the following terms 1. Encapsulation 2. Interface 3. Inheritance 4. Visibility modifiers - public, private, protected 5. super() methodنقطة واحدة which application of oop can be provide a degree of freedom in the :interface design option Inheritance Object and class polymorphism Friend functionsJava A class always has a constructor that does not take any parameters even if there are other constructors in the class that take parameters. Choose one of the options:TrueFalse
- In java language on netbeans design a console application that will print the game sales for a particular game in 2021. Use an abstract class named Games that contains variables to store the game name, game genre and the total sales. Create a constructor that accepts the game name, game genre and the total game sales as parameters. In this class also create get methods for the variables. The Games class must implement an iGames interface that contains the following: public interface iGames { public void printSales(); public String getGame(); public String getGameGenre(); public int getGameSales(); } Create a subclass called Game Sales that extends the Games class. The Games Sales class must contain a constructor to accept the game name, game genre and total game sales as parameters. Then, write code for the Print Sales method, which prints the game sales report for 2021. Finally, write a Use Games class to instantiate the Games Sales class.The non-static class level variables and non-static methods of a class are known as a. instance members b. object behaviors c. object attributes O d. object referencesjava A constructor is a special method that has the same name as the class and the return type void. Choose one of the options:TrueFalse
- Which of the following does NOT apply to the strategy design pattern? It can change the behavior of a class at runtime It can eliminate conditional statements It can reduce the communication overhead between objects It provides an alternative to subclassing None of aboveObjectives: At the end of this activity, you should be able to: define classes implement polymorphism and inheritance instantiate an object array apply Exception to all input validations create a Java application for multiple users Procedure: Create a NetBeans project for this activity. The project name should be as follows: o Client (the main class that contains the main method and the implementation of the main menu) o Credit (the class where attributes and methods are defined) The class names to be created are the following: o Client<your_last_name> Ex. ClientBlancoo Credit<your_last_name> Ex. CreditBlanco All class names must be suffixed with your last name. Note that the object to be instantiated in the main method is an object array.For example: CreditBlanco [ ] cb = new CreditBlanco [100]; Compress the NetBeans project into .rar or .zip format and then upload to the link provided in the LMS. Only NetBeans project compressed in .rar or .zip format will be…In Java programming (Lesson: Objects, Classes, and Constructors) Every class has a constructor and if we do not explicitly write a constructor for a class, the java compiler builds a default constructor for that class. False or True Please provide an explanation for the answer. Thank you!
