Create a class named Person that holds the following fields: two String objectsfor the person’s first and last name and a LocalDate object for the person’sbirthdate. Create a class named Couple that contains two Person objects. Create aclass named Wedding for a wedding planner that includes the date of the wedding,the names of the Couple being married, and a String for the location. Provideconstructors for each class that accept parameters for each field, and provide getmethods for each field. Then write a program that creates two Wedding objectsand in turn passes each to a method that displays all the details. Save the files asPerson.java, Couple.java, Wedding.java, and TestWedding.java.
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 works
Create a class named FootballTeam. Include two fields that hold data about theteams participating in the game. Also include a field for game time (for example, 5PM). Include a constructor that takes parameters for two FootballTeam objects anda time. From the main method, instantiate a FootballTeam object, then pass theGame to a method that displays the details about the FootballTeam.

- Create an application named SalesTransactionDemo that declares several SalesTransaction objects and displays their values and their sum. The SalesTransaction class contains fields for a salesperson name, sales amount, and commission and a readonly field that stores the commission rate. Include three constructors for the class. One constructor accepts values for the name, sales amount, and rate, and when the sales value is set, the constructor computes the commission as sales value times commission rate. The second constructor accepts a name and sales amount, but sets the commission rate to 0. The third constructor accepts a name and sets all the other fields to 0. An overloaded + operator adds the sales values for two SalesTransaction objects.arrow_forwardCreate an application named CarDemo that declares at least two Car objects and demonstrates how they can be incremented using an overloaded ++ operator. Create a Car class that contains a model and a value for miles per gallon. Include two overloaded constructors. One accepts parameters for the model and miles per gallon; the other accepts a model and sets the miles per gallon to 20. Overload a ++ operator that increases the miles per gallon value by 1. The CarDemo application creates at least one Car using each constructor and displays the Car values both before and after incrementation.arrow_forwardWrite a program named DemoJobs for Harolds Home Services. The program should instantiate several Job objects and demonstrate their methods. The Job class contains four data fields—description (for example, wash windows), time in hours to complete (for example, 3.5), per-hour rate charged (for example, $25.00), and total fee (hourly rate times hours). Include properties to get and set each field except the total fee—that field will be read-only, and its value is calculated each time either the hourly fee or the number of hours is set. Overload the + operator so that two Jobs can be added. The sum of two Jobs is a new Job containing the descriptions of both original Jobs (joined by and), the sum of the time in hours for the original Jobs, and the average of the hourly rate for the original Jobs. Harold has realized that his method for computing the fee for combined jobs is not fair. For example, consider the following: His fee for painting a house is $100 per hour. If a job takes 10 hours, he earns $1000. His fee for dog walking is $10 per hour. If a job takes 1 hour, he earns $10. If he combines the two jobs and works a total of 11 hours, he earns only the average rate of $55 per hour, or $605. Devise an improved, weighted method for calculating Harolds fees for combined Jobs and include it in the overloaded operator+() method. Write a program named DemoJobs2 that demonstrates all the methods in the class work correctly.arrow_forward
- Create an application class named LetterDemo that instantiates objects of two classes named Letter and CertifiedLetter and that demonstrates all their methods. The classes are used by a company to keep track of letters they mail to clients. The Letter class includes auto-implemented properties for the name of the recipient and the date mailed. Also, include a ToString() method that overrides the Object classs ToString() method and returns a string that contains the name of the class (using CetType and the Letters data field values. Create a child class named CertifiedLetter that includes an auto-implemented property that holds a tracking number for the letter.arrow_forwardYou are designing an application to rate your professors.a. Professors have the following properties: first name, last name, universityname, subject, and ratings for overall quality (1.0-5.0) and level of difficulty(1.0-5.0). Your class should have instance variables of the appropriatetype for each property.b. Your class should have two constructors: one that takes all properties, andone that takes only first name, last name, university name, and subjectand sets both of the ratings to an appropriate default value.c. You should provide accessors (getters) and mutators (setters) for firstname, last name, university name, and subject.d. Your class should provide a method to add a new rating for the professor.It should take two arguments: one for overall rating and one for level ofdifficulty, with values from 1 (awful) to 5 (awesome). Each time a newrating is provided, your class should calculate the average rating for theprofessor and update the appropriate variable for each.e.

The class has five properties that include a job number, customer name, job description, estimated hours, and price for the job. Create a constructor that requires parameters for all the data except price. Include auto-implemented properties for the job number, customer name, and job description, but not for hours or price; the price field value is calculated as estimated hours times $45.00 whenever the hours value is set. Also create the following for the class: •An Equals() method that determines two Jobs are equal if they have the same job number •A GetHashCode() method that returns the job number •A ToString() method thatreturns a string containing all job information The JobDemo application declares a few Job objects, sets their values, and demonstrates that all the methods work as expected. b.Using the Job class you created in Exercise 3a, write a…arrow_forward
- Create a C# application named CarDemo that declares at least two Car objects and demonstrates how they can be incremented using an overloaded ++ operator. Create a Car class that contains the following properties: Model - The car model (as a string) Mpg The car's miles per gallon (as a double) Include two overloaded constructors. One accepts parameters for the model and miles per gallon; the other accepts a model and sets the miles per gallon to 20. Overload the ++ operator that increases the miles per gallon value by 1. The CarDemo application creates at least one Car using each constructor and displays the Car values both before and after incrementation.arrow_forwardThis is the question - Create a class named Apartment that holds an apartment number, number of bedrooms, number of baths, and rent amount. Create a constructor that accepts values for each data field. Also create a get method for each field. Write an application that creates at least five Apartment objects. Then prompt a user to enter a minimum number of bedrooms required, a minimum number of baths required, and a maximum rent the user is willing to pay. Display data for all the Apartment objects that meet the user’s criteria or No apartments met your criteria if no such apartments are available. This is the code it has given and I have done some on- public class Apartment { int aptNumber; int bedrooms; double baths; double rent; public Apartment(int num, int bdrms, double bths, double rent) { } public int getAptNumber() { return aptNumber; } public int getBedrooms() { retrun bedrooms; } public double getBaths() {…arrow_forwardThis is the question - Create a class named Apartment that holds an apartment number, number of bedrooms, number of baths, and rent amount.
