OOP (Object-Oriented Programming) in Java Applying the composite pattern, you may create a replica of any environment you choose. Any number of media may be used, from photographs to simulators to movies to video games, and so on.

Define the term " operator indirection " .

“Dangling and wild pointers are known to be problems with pointers”. Justify the given statement with the help of suitable examples. -C language

(JAVA) What is code refactoring?   Group of answer choices   A)None of the options are correct.   B) It is changing implementation of a method or constructor of a class, while leaving the declaration the same, allowing all users of that class to continue using the class without noticing the change.   C)It is abstracting a class so that common elements with another class are moved into the abstract class that both classes extend.   D) It is declaring all the methods that need to be supported in an interface. This guarantees that all classes implementing this interface will support those methods.

(Student Inheritance Hierarchy) Draw an inheritance hierarchy for students at a universitysimilar to the hierarchy shown in Fig. 19.2. Use Student as the base class of the hierarchy, then include classes UndergraduateStudent and GraduateStudent that derive from Student. Continue toextend the hierarchy as deep (i.e., as many levels) as possible. For example, Freshman, Sophomore,Junior and Senior might derive from UndergraduateStudent, and DoctoralStudent and MastersStudent might derive from GraduateStudent. After drawing the hierarchy, discuss the relationships that exist between the classes. [Note: You do not need to write any code for this exercise.]

Define a class Employee. Display the personal and salary details of five employees using single inheritance. (in C++)

(Inheriting Interface vs. Inheriting Implementation) A derived class can inherit “interface” or “implementation” from a base class. How do inheritance hierarchies designed for inheriting interface differ from those designed for inheriting implementation?

13) What is the purpose of polymorphism in Java? To provide encapsulation of data and methods To allow objects of different classes to be treated as if they are of the same class To define behavior of a class To provide access to interface methods 14) True or False Polymorphism allows objects of different classes to be treated as if they were of the same class.
