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:

Question

In Mammal, if the 4th line: super (age); is replaced with the line: this.age = age;
then the result would be:
The age is set only for Mammal, not for Animal
The will not be set.
The class Mammal won't compile
The class Animal won't compile
age

public class Animal
{
public static int population;
private int age;
}
public Animal (int age) {
this.age = age;
population++;
}

Write a "proper" Polygon class, using "proper" class design. It needs to have: 1) The number of sides it has (an int) and it's x and y location (both floats) as private member variables. 2) Accessors and mutators for the member variables. (AKA getters/setters.) 3) Constructors to set the member variables when the class is initialized

In a particular factory, a team leader is an hourly paid productionworker that leads a small team. In addition to hourly pay, team leaders earn a fixed monthly bonus. Team leaders are required to attend a minimum number of hours of training per year. Design a TeamLeader class that is derived from the ProductionWorker class you created in Programming Problem 1. The TeamLeader class should have properties for the monthly bonus amount, the required number of training hours, and the number of training hours that the team leader has attended. Demonstrate the class in an application.

An organization has two types of employees: regular and adhoc. Regular employees get a salary which is basic + DA + HRA where DA is 10% of basic and HRA is 30% of basic. Adhoc employees are daily wagers who get a salary which is equal to Number * Wage ) Define the classes shown in the following class hierarchy diagram: Employee name eno salary ) Regular Adhoc wage mber days (int n) salary () Basic salary () (ii) Define the constructors. When a regular employee is created, parameter. basic must be a parameter When adhoc employee is created wage must be a parameter. (ii) Define the destructors. (iv) Define the member functions for each class. The member function days ( ) updates number of the Adhoc employee. (v) Write a test program to test the classes.
You have to implement program that compares graduate students based on their ranks. The design of the program is given in the following UML diagram: • Student class: Base class that GradStudent extends. • GradStudent class: The objects from this class will be used for comparisons. • Rankable interface: Defines the implementation needed for comparison. GradStudent implements this interface. • Test class will be used to get student information from the user and demonstrate the comparison of students.
Design a class that implements the basic properties of a die. Consider the definition of the following class die.(Beginner) class die { public: die(); //Default constructor //Sets the default number rolled by a die to 1 void roll(); //Function to roll a die. //This function uses a random number generator to randomly //generate a number between 1 and 6, and stores the number //in the instance variable num. int getNum() const; //Function to return the number on the top face of the die. //Returns the value of the instance variable num. private: int num; }; a) Write the definitions of the functions to implement the operations for the class die. b) Write a program that uses the class die to roll 10 dice. (Use an array of size 10 to implement 10 dice.) The program prompts the user to enter the desired sum and the number of times the dice are to be rolled. The program outputs the number of times the desired sum was rolled. Test run your program to roll the 10 dice 10000 times with the desired…
The Point2D should store an x and y coordinate pair, and will be used to build a new class via class composition.

15. Suppose the class Employee is declared as follows: public class Employee { private String name; private double baseSalary: public void setName(String newName) {...} public void setBasSalary(double newSalary){...} public String getName() {...} public double getSalary({...} } a)Declare a class Manager that inherits from the class Employee and adds an instance variable bonus for storing a salary bonus. Omit constructors and methods. ANS: b) Which instance variables does the Manager class have? c) In the manager class, provide the method overrides the getSalary method from the class Employee so that it returns the sum of the salary and the bonus d) Based on the above question, which methods does the manager class inherit? e) In the manager class, override the getName method so that managers have a before their name (such as *John Smith).
