You have a class named HeartsPlayerA round of Hearts starts with every player having 13 cardsPlayers then choose 3 cards to “trade” with a player (1st you pass left, 2nd you pass right, 3rd you pass across, 4th you keep)Players then strategically play cards in order to have the lowest scoreAt the end of the round, points are cumulatively totaled for each player.If one player’s total is greater than 100, the game ends and the player with the lowest score wins.
1. How should the following data fields be defined (with respect to final and static)?(a) playerPosition (These have values of North, South, East, or West)(b) directionOfPassing(c) totalScore…
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…
Create a class named Grades, which has four fields, one for the name of the student, and three other fields for grades in test1, test2 and test3. The class should contain two constructors: a no-argument constructor that sets all fields to zero, and a constructor that sets all fields to a given value. The class should have the appropriate methods to “set” and “get” the values of all fields. The class should also have a method to calculate the average of the three tests. To test the class, you should create a class demo that instantiates one object of the Grades class and asks the user enter the student name and the grades for the three tests. The program should set the fields to the values entered by the user using the “set” methods, and output to the console the student name, the grades for test1, test2 and test3 as well as their average using “get” methods.
