OOPs
In today's technology-driven world, computer programming skills are in high demand. The object-oriented programming (OOP) approach is very much useful while designing and maintaining software programs. Object-oriented programming (OOP) is a basic programming paradigm that almost every developer has used at some stage in their career.
Constructor
The easiest way to think of a constructor in object-oriented programming (OOP) languages is:
When a class can be derived from another class and use its methods, this is called Polymorphism.
A. True
B. False
Step by step
Solved in 3 steps
- Polymorphism is the feature that allow different implementations of the same class to behave differently Select one: O True False18. If a class is declared as final, the incorrect statement is (). A. Indicates that this class is final B. Indicates that this class is a root class C. Methods in this class cannot be overridden D. Variables in this class cannot be hidden 19. In the following description of polymorphism, the incorrect one is (). A. Polymorphism refers to "one definition, multiple implementations" B. There are three types of polymorphism: dynamic polymorphism, static polymorphism, and default polymorphism C. Polymorphism is not used to speed up code D. Polymorphism is one of the core characteristics of OOP 20. In Java, two interfaces B and C have been defined. To define a class that implements these two interfaces, the correct statement is ( ). A. interface A extends B,C B. interface A implements B,C C. class A implements B,C D. class A extends B,C 21. Given the following java code, the correct description of the usage of "super" is (). class Student extends Person{ public Student() { super(); } 3 D…Design a new Triangle class that extends the abstract GeometricObject class: Draw the UML diagram for the classes Triangle and GeometricObject Implement the Triangle class Write a test program that prompts the user to enter three sides of the triangle, a color, and a Boolean value to indicate whether the triangle is filled: The program should create a Triangle object with these sides and set the color and filled properties using the input The program should display the area, perimeter, color, and true or false to indicate whether it is filled or not
- Overloading is achieved when two or more methods in the same class have the sameTrue or False An interface can be used to define a set of methods that a class must implement.Create a class Animal and Add a protected data member named id of integer type. Add get/set methods for id data member in Animal class with public access. Also provide default constructor this should initialize id to 0. Also provide parameterized constructor and toString method. Add an abstract method tellAboutSelf method to Animal class with public access Add another abstract method speak method to Animal class. Reptile, Bird, Mammal Next create the three child classes which extends form Animal class. Add a default constructor to each of the above created class. The constructor should initialize the id data member id, Reptile, Bird and Mammal, to 1, 2 and 3 respectively also it display a message “(class Name)’s default constructor”. E.g. for Bird it says “Bird’s default constructor”. Add a parameterized constructor to each of the above created class. The constructor should initialize the id data member, Reptile, Bird and Mammal, to the specified id passed to the constructor also it…
- True/False: When instantiating an object of an abstract class, you can do it with the keyword new.public class date { private int day; // from 1 to 31 private int month; // from 1 to 12 private int year; // from 2000 upwards public void advance (); // move to next day }; Implement a constructor that initializes new objects of date class to be set to the 1st of January 2000. Implement setters for day, month, and year. Implement the advance method, which moves to the next day, ensuring that all data members are updated appropriately.Which of the following are not true about polymorphism? A It means single form. B It is the passing of variables to a child class. © It is the method of recycling a block of code and changing it to another form. D It is the method used for the protection of data. E) None of the other choices are correct.
- •Person Class: Person class has attributes: String name, address and int age. Write setperson() function to set values and getPerson() to Print attributes. Also write appropriate constructors.•Employee Class: Write another class Employee having attributes department and salary of type string and double. Write methods setEmployee(), getEmployee() and appropriate constructors for Employee class.•Student Class:•Write a class Student having attributes registration number and GPA of type string and float. Also write setStudent(), getStudent() methods and required constructors. Use the concept of inheritance to achieve the above functionality. Write a main() function to display the information of employee and student.• Note: Call the constructors/methods of parent class in child class where required in java code•Person Class: Person class has attributes: String name, address and int age.
