- 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_forwardMicrosoft Visual C# 7th edition. In Chapter 7, you modified the GreenvilleRevenue program to include a number of methods.

- This 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 I already have. It doesn't seem to like under TestApartments my apt. variable. I am unsure what to do to fix this cause it doesn't like any of my code - public class Apartment { int aptNumber; int bedrooms; double baths; double rent; public Apartment(int num, int bdrms, double bths, double rent) { //write code here aptNumber = num;…arrow_forwardThis is the question - Create a class named Apartment that holds an apartment number, number of bedrooms, number of baths, and rent amount.

In the JavaScript file, note the $(), displayCurrentTime(), padSingleDigit(), and DOMContentLoaded event handler functions from the Clock application. In addition, note the global variables and starting code for the tickStopwatch(), startStopwatch(), stopStopwatch(), and resetStopwatch() functions. 3. In the tickStopwatch() function, add code that adds 10 milliseconds to the elapsedMilliseconds variable and then adjusts the elapsedMinutes and elapsedSeconds variables accordingly.
