1. Programming Exercise 3- 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 O, 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 neede 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 application to test the new version of the class, and name it TestFitness Tracker? in
