Question

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…

Instructions: IMPORTANT: This is a continuation of the previous part of the project and assumes that you are starting with code that fulfills all requirements from that part of the project. Modify the your code from the previous part of the project to make it modular. In addition to the main method, your code must include the following static methods: Method 1 - displayTitle A method that creates a String object in memory to hold the text “Computer Hardware Graphics Quality Recommendation Tool” and displays it Method 2 – getResolutionString A method that accepts an integer value (1, 2, 3, or 4) that denotes the monitor resolution. The method should return the appropriate String representation of the monitor resolution. For example, if the method is passed an integer value of 1, it should return a String with a value of “1280 x 720”. (See Step 4 of Project 1) Method 3 – getMultiplierValue A method that accepts an integer value (1, 2, 3, or 4) that denotes the monitor resolution and…

Create a class for Subject containing the Name of the subject and score of the subject. There should be following methods: set: it will take two arguments name and score, and set the values of the attributes. If score is less than 0 or greater than 100.0 then a message should be displayed “Incorrect score” and score should be set to Zero. set: it will take one double value as argument and set the value of score only. If score is less than 0 or greater than 100.0 then a message should be displayed “Incorrect score” and score should be set to Zero. display: it will display the name and score of the subject. Like “Name : Math, Score: 99.9” getScore: it will return the value of score. greaterThan: it will take subject’s object as argument, compare the calling object’s score with argument object’s score and return true if the calling object has greater score. note....... solve with java
