- a - Create a 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. Save the file as FitnessTracker.java. Create an application that demonstrates each method works correctly, and save it as TestFitnessTracker.java. 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 application to ensure that the overloaded constructor works correctly, save it, and then test it. c - Modify the FitnessTracker class so that the default constructor calls the three-parameter constructor. Save the class as FitnessTracker2.java. Create an…arrow_forwardWrite a class named RetailItem that holds data about an item in a retail store.

- in C#, Visual Basic Create a Car class that has at least the following properties:• Year• Make• Price• Passengers-holds the number of seat belts available in the car (presumably how many passengers the car can hold). This field must be private since users presumably can’t change this value. Have two constructors: one that initializes everything to some default value for the base price of a car and one that also accepts values for luxury upgrades of: heated seats, sun-roof, and satellite radio. The class has two methods: 1) Get Paint Color() which accepts a standard base color option but allows the user to purchase a pricier customized color 2) Upgrade Costs() which computes the cost of user-selected luxury items and adds it to the price. Create three car objects: Ford (make Explorer), Lexus (make ES) and a Clown Car which overrides the passenger value to allow 20 clowns in the car. The Get Paint Color() and Upgrade Costs() functions needs to be called for each object and data for all…arrow_forwardAppointment Class Requirements The appointment object shall have a required unique appointment ID string that cannot be longer than 10 characters. The appointment ID shall not be null and shall not be updatable. The appointment object shall have a required appointment Date field. The appointment Date field cannot be in the past. The appointment Date field shall not be null.Note: Use java.util.Date for the appointmentDate field and use before(new Date()) to check if the date is in the past. The appointment object shall have a required description String field that cannot be longer than 50 characters. The description field shall not be null. Appointment Service Requirements The appointment service shall be able to add appointments with a unique appointment ID. The appointment service shall be able to delete appointments per appointment ID.arrow_forward2. Car Class Write a class named car that has the following fields: ▪ yearModel. The year Model field is an int that holds the car's year model. ▪ make. The make field is a String object that holds the make of the car, such as "Ford", "Chevrolet", "Honda", etc. ▪ speed. The speed field is an int that holds the car's current speed. In addition, the class should have the following methods. ■ Constructor. The constructor should accept the car's year model and make as arguments. These values should be assigned to the object's year Model and make fields. The constructor should also assign 0 to the speed field.arrow_forward

So you take the current volume, increase it by 2.5%, and then find the cube root to calculate the new side length. You can use the built in function called cbrt, part of the math library, to find the cube…arrow_forwardIn C#, Create a program named ConferencesDemo for a hotel that hosts business conferences. Allows a user to enter data about five Conference objects and then displays them in order of attendance from smallest to largest. The Conference class contains fields for the following: group - The group name (as a string) date - The starting date (as a string) attendees - The number of attendees (as an int) Include properties for each field. Also, include an IComparable.CompareTo() method so that Conference objects can be sorted in order from least to greatest attendees.arrow_forward
