5. State whether the following statements are TRUE or FALSE (PS: No explanation is needed and very optional)(a) One of the striking features of object-oriented programming is the division of programs into objects that represent real-world entities.(b) Inheritance means ability to reuse the data values of one object by other objects.(c) Wrapping up of different types into a single unit is known as encapsulation.(d) One problem with OOP is that once a class is created, it can never be changed.(e) Object-oriented programs are executed much faster than conventional programs.

(Java) The Abstract Art Class Write an abstract class as follows: The class is named Art It inherits from the Comparable interface It has a private String member variable named name It has a private String member variable named artist It has a private int member variable called year It has a default constructor that assigns the values "No name" to name, "No artist" to artist and -1 to the year. This default constructor calls the three argument constructor. It has a three-argument constructor to assign values to the name, artist and year variables. It has a copy constructor that makes a copy of another non-null Art object It has getters and setters for the name, artist and year variables It has a toString() method that creates a string of artist, with name and year tabbed once on subsequent lines (see sample output) It has an equals method that compares this Art to another Object It has a compareTo method that compares in this order: 1) artist, 2) name, 3) year This class contains no…

C#   How to call a base class constructor from a derived class constructor, also how to call another constructor from one constructor in the same class? Give example.

C++ Programming. Build a class with the fields and methods specified in the individual task (Table 1):- constructor;- displaying the value of the fields;- changes in field values;- overloading the operation specified in individual tasks (see Table 1, column 2)

Differentiate between static and instance class members. Explain with proper example when you should make members static?

a class can be instaniated from an object (true/false) we use pointer variable to reference objects stored in the heap memory (true/false) a class diagram can only be implemented using C++ (true/false)

C++ Programing NOTE: The important method has been ATTRIBUTES given to you. userld:int //generates unique id from 10001 upwards INSTRUCTION 1 username:string firstname:string lastname:string dob:string The program should generate unique userld whenever new object is created. Notice that idGenerator is static variable, so assign the current value of idGenerator to userld, so that each user will have unique user id (Starting from 10001). age: int idGenerator: static int; totalUsers : static int МЕТHODS User() User(string, string, string, int) User(const User&) "User() Then increment idGenerator by 1. INSTRUCTION 2 The totalusers is also a static variable. This should keep track of the total users in the class. With the Above UML for CLASS USER, answer the following questions Complete or Create the default constructor method. a. The default constructor should accept just the firstname, lastname, dob (date of birth) and age from the keyboard. wwww w b. Write a setter method that sets the…

Mixed Fraction Arithmetic Java Project: Problem Description: Make a java program that facilitates addition, subtraction, multiplication, and division of mixed numbers (similar with the first activity) but this time all of the inputs /outputs may involve fractions, mixed fractions, or a combination.   Points to consider:   MixedFraction class must override the operations (add, subtract, multiplyBy, divideBy) inherited from Fraction class to have a different implementation if the MixedFraction object will have a Fraction object as parameter in performing the required operation, On top of that, the inherited operations must also be overloaded to allow a MixedFraction object to accept other parameters such as a whole number or another MixedFraction object. The toString method which is inherited must also be overridden by MixedFraction to have a more appropriate return value. Further formatting must also be considered such that if the result of the operation has a zero value for the whole…

Explain the concept of object versioning in serialization. How can you handle changes in a class's structure while maintaining backward compatibility?
