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:
A __________ is a constructor that accepts no arguments.
a. parameterless constructor
b. basic constructor
c. primary constructor
d. passive constructor

- There is only one type of constructor and it is a constructor that does not take any parameters. Choose one of the options:TrueFalseA constructor that accepts __________ parameters is called the default constructor. three one no twoA constructor is a special method that has the same name as the class and the return type void. Choose one of the options:TrueFalse
- In this exercise, you have to create a class called Point which can calculate distance between two points in the x-y plane. Problem Statement# You have to implement a class called Point that represents a specific point in the x-y plane. It should contain the following: ● fields: ○ x( integer type) ○ y( integer type) ● methods: ○ default constructor that initializes the point at (0,0)(0, 0)(0,0) ○ parameterized constructor that takes input x and y and initializes the point to the respective coordinates. ○ float distance(), a method which calculates the distance of the point (represented by the object) from the origin, i.e. (0,0)(0, 0)(0,0) ○ float distance(x1, y1), a method which calculates the distance between the point represented by the class object and (x1,y1)(x1, y1)(x1,y1) Sample Input# Point p1 = new Point(5, 5); Sample Output# distance() => 7.071 distance(2, 1) => 5.0 Part of the solution import java.lang.Math; class Point { // Private fields private int x;…a. Modify the FitnessTracker class that includes data fields for a fitness activity, the number of minutes spent participating, and the date. The class includes methods to get each field. In addition, create a default constructor that automatically sets the activity to running, the minutes to 0, and the date to January 1 of the current year. Create an application that demonstrates each method works correctly. b. Create an additional overloaded constructor for the FitnessTracker class you created in Exercise 3a. This constructor receives parameters for each of the data fields and assigns them appropriately. Add any needed statements to the TestFitnessTracker.java application to ensure that the overloaded constructor worksA special set of methods, known as __________, work in conjunction with a private field and allow code outside the class to get the property’s value, and assign values to the property. a. accessors b. imitators c. intermediates d. directives
- Create a constructor for the Student class you created. The constructor should initialize each Student’s ID number to 9999, his or her points earned to 12, and credit hours to 3 (resulting in a grade point average of 4.0). Write a program that demonstrates that the constructor works by instantiating an object and displaying the initial values. Save the application as ShowStudent2.java.JAVA - USING CONSTRUCTORS Create a class named House that includes data fields for the number of occupants and the annual income as well as methods named setOccupants(), setIncome(), getOccupants() and getIncome() that set and return those values respectively. Additionally, create a constructor that requires no arguments and automatically sets the occupants field to 1 and income field to 0. Create an additional overloaded constructor . This constructor receives an integer argument and assigns the value to the occupants field. Create a third overloaded constructor this time, the constructor receives 2 arguments, the values of which are assigned to the occupants and income fields respectively. Create another class named I_house that instantiates the House class and see if the constructors work correctly.Write a class named Employee that has the following fields:• name. The name field references a String object that holds the employee’s name.• idNumber. The idNumber is an int variable that holds the employee’s ID number.• department. The department field references a String object that holds the name ofthe department where the employee works.• position. The position field references a String object that holds the employee’sjob title.The class should have the following constructors:• A constructor that accepts the following values as arguments and assigns them to theappropriate fields: employee’s name, employee’s ID number, department, andposition. • A constructor that accepts the following values as arguments and assigns them to theappropriate fields: employee’s name and ID number. The department and positionfields should be assigned an empty string (""). • A no-arg constructor that assigns empty strings ("") to the name, department, andposition fields, and 0 to the idNumber field.…
- Design a console application that will print the fine due for a citizen who was caught speeding in a 120km zone. Make use of an abstract class named Fine that contains variables to store the citizen name, speed and fine payable. Create a constructor that accepts the citizen name and speed as parameters and create get methods for the variables. The Fine class must also contain a method to calculate the fine. If the speed is greater than or equal to 120km, multiply the speed by R10.20, or else no fine if payable. The Fine class must implement an iFine interface that contains the following: public interface iFine { public void PrintFine(); } Create a subclass called SpeedingFines that extends the Fine class. The SpeedingFines class must contain a constructor to accept the citizen name and speed as parameters. Write code for the PrintFine() method which displays the citizen name, speed and the total fine due. Finally write a SpeedingFineApplication class to capture the input and…Design a console application that will print the fine due for a citizen who was caught speeding in a 120km zone.

(Hints: use the remainder operator) (Multiples) Write an app that reads two integers, determines whether the first is a multiple of the second, and displays the result. (Hints: use the remainder operator). Create a class called Date that includes three pieces of information as auto-implemented properties: a month (type int), a day (type int), and a year (type int). Your class should have a constructor that initializes the three fields. Provide a method DisplayDate() that displays the three fields (separated by '/'). Write a test app named DateDemo that demonstrates class Date’s capabilities.
