Answer in your words , no plagiarism please. I will downvote. Thankyou . Generalization is the relationship between a superclass and one or more subclasses.The superclass is more general and it holds common attributes, operations and associations. Whereas the subclass is more specific. It uses the common attributes, operations and association of superclass but adds its specific attributes, operations and associations.Generalization is also called as is-a relationship. This is because, each instance of subclass is an instance of the superclass.Generalization relationship can be represented using an arrow having hollow arrowhead. The arrowhead points to the superclass. Explain the use of Generalization.
Question 30 Which of the following description is TRUE? Inheritance allows us to define a class based on another class. Child classes receive all the features from the parent class but can NOT have their own additional features. Abstraction means that a method in a parent class can have a number of different implementations in child classes. An interface is a completely abstract class, which contains abstract properties, methods, and variables. The private access modifier makes members accessible only from within the class and hides them from the outside.
QUESTION 8 Which of the following statements is wrong about inheritance? A. The inheriting class is called a subclass B. Inheritance is one of the features of OOP C. Protected members of a class can be inherited D. Private members of a class can be inherited and accessed
What is a delegate object? Group of answer choices 1. It is a way to unit test your code, by delegating certain tests to one object, and other tests to another. This makes each test clear and puts all related tests in a single object. 2. It’s a way to reuse code through composition. We delegate certain responsibilities to an object that can handle those responsibilities. 3. It’s a way to reuse code through inheritance. The parent class is the delegate object because the child delegates certain responsibilities to the parent class by using the inherited methods without overriding. 4. A delegate object is when you create multiple instances of the same class. One object is created for certain purposes, while the other is delegated to take care of similar purposes. While both objects are from the same class they have different specific purposes.
Which of the following are not true about inheritance? (Multiple choice can be selected) A It is the pillar of the OOP paradigm that states that a class' variables and methods can be duplicated by its child classes by inheriting them. B It is done to avoid duplication of codes. C It is used to conceal the implementation of codes. D It is used to protect the integrity of data. E None of the other choices are correct.
C++ please help me answer this question I will give you a good rating Thank you! Choose the correct answer to the question. A derived class... a. Can contain more attributes (data members) and behaviors (methods) than its base class. b. Can be the base class for other derived classes.c. Object can access all data members with the dot operator. d. Object can be assigned to a reference of the base class. a, b only.a,b,d only.All of the above. Choose the correct answer to the question. Which of the following can be changed when overloading an operator? The precedence of the operator.The associativity of the operatorThe arity (number of operands) of the operator. All of the aboveNone of the above
C++ please help me answer this question I will give you a good rating Thank you! 1. True or False? Explain your answer. Explain why? _____ Two classes that exist in the same program can have functions with the same name or variables with the same name. Explain your answer above. Explain why? _____ When using inheritance, the derived objects are constructed first and the base class object at the top of the hierarchy is constructed last. True False _____ Default constructors are inherited from the base class, thereby eliminating the need for derived classes to define their own default constructors. _____The extraction operator>> and the insertion operator<< returns a istream and ostream reference respectively so that input and output operations can be chained. _____ Once a constructor is used for an individual object, you cannot use a constructor with that object again. True False 19. Explain your answer above. Explain why?
JAVA PROGRAMMING (TRUE OR FALSE) No further explaination needed. Classes in the java·lang package may be used directly if they are imported first using an import statement(True/False) The fields and methods of a child/sub class are only those inherited from the parent/super class.(True/False) A reference/object of super class type can hold/assume any object of its sub class type.(True/False) An import statement is necessary to use/access a classin the same package.(True/False) A private data field is accessible only by other classes via the exposed methods of its class.(True/False)
Part-2 (Encapsulation, Inheritance, Polymorphism) ____________________________________________________________________________ Create a Java project that demonstrates various object oriented concepts you have learned so far in this course (encapsulation, inheritance and polymorphism). To do this, create a super class and at least 2 subclasses. You can either do multilevel inheritance or hierarchical inheritance in this to complete this part-2 task. The super class will have following properties/functionalities:a) Create a total of 3 member variables for the class, selecting the appropriate data types for each field. b) Include an argument constructor in this Class, that will initialize all data fields. c) Encapsulate this Class.The two subclasses will have below properties/functionalities:a) One of the subclasses will have at least one member variable and other subclass with at least two member variables. b) Have two constructors in each subclass:• One constructor for initializing only…

1)In the C++ code segment below, which of the following are valid reasons for making vUnit a member of myClass2? class myClass1 { //other details omitted}; Class myClass2 { myClass1 vUnit; //other details omitted}; A)It allows for polymorphism. It models a has-a relationship in myClass2 to myClass1. B)It uses less memory that inheritance. C)It is a short-hand notation for inheritance. D)It gives myClass2 faster access to myClass1 than could be achieved via inheritance. 2)which of the following represent valid use cases of the ANSI C register storage class specifier? A)A for loop in which the loop index is declared in the initialization. B)A short int inside a block which will be passed by pointer to another function. C)An unsigned short defined inside a function combined with other quantities as a bitmask. D)A parameter list of an external function declared in a header file. E)A char array declare at file…
