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 called Student that has the following attributes:• __first_name• __last_name• __final_scoreThe class should have following methods:• letter_grade: calculates the letter grade based on final• display_student_info: displays student informationWrite a Python program that creates at least five objects based on Student class. Use display_student_info method to print each object’s information as output including letter grade. Please modify the class if you think letter_grade needs to be stored as well for a class object
Part A
Create a class named Apartment that holds an apartment number as aptNumber, number of bedrooms as bedrooms, number of baths as baths, and rent amount as rent.
Create a default constructor that accepts no arguments and an overloaded constructor that accepts values for each data field.
Also create a get method for each field.
Part B
Write an application called TestApartments 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 an appropriate message if no such apartments are available.
An example of the program is shown below:
Enter minimum number of bedrooms needed >> 2
Enter minimum number of bathrooms needed >> 1.5
Enter maximum rent willing to pay >> 1200
Apartments meeting criteria of
at least 2 bedrooms, at least 1.5 baths, and no more than…

- In previous chapters, you have created programs for the Greenville Idol competition. Now create a Contestant class with the following characteristics: The Contestant class contains public static arrays that hold talent codes and descriptions. Recall that the talent categories are Singing Dancing, Musical instrument, and Other. The class contains an auto-implemented property that holds a contestants name. The class contains fields for a talent code and description. The set accessor for the code assigns a code only if it is valid. Otherwise, it assigns I for Invalid. The talent description is a read-only property that is assigned a value when the code is set. Modify the GreenvilleRevenue program so that it uses the Contestant class and performs the following tasks: The program prompts the user for the number of contestants in this years competition; the number must be between 0 and 30. The program continues to prompt the user until a valid value is entered. The expected revenue is calculated and displayed. The revenue is $25 per contestant. The program prompts the user for names and talent codes for each contestant entered. Along with the prompt for a talent code, display a list of the valid categories. After data entry is complete, the program displays the valid talent categories and then continuously prompts the user for talent codes and displays the names of all contestants in the category. Appropriate messages are displayed if the entered code is not a character or a valid code.arrow_forwardCreate an application named SalesTransactiobDemo that declares several SalesTransaction objects and displays their values and their sum. Name - The salesperson name (as a string) sales Amount- The sales amount (as a double) commission- The commission (as a double) RATE- A readonly field that stores the commission rate (as a double). Define a getRate() avcessor method that returns the RATE Include 3 constructors for the class. One constructor accepts values for the name, sales amount, and rate, and when the sales value is set, the constructor computes the commission as sales value times commission rate. The second constructor accepts a name and sales amount, but sets the commission rate to 0 The third constructor accepts a name and sets all the other fields to 0arrow_forwardA company accepts user orders by part numbers interactively. Users might make the following errors as they enter data: - The part number is not numeric. The quantity is not numeric. - The part number is too low (less than 0). - The part number is too high (more than 999). - The quantity ordered is too low (less than 1). - The quantity ordered is too high (more than 5,000). Create a class that stores an array of usable error messages; save the file as DataMessages.java. Create a DataException class; each object of this class will store one of the messages. Save the file as DataException.java. Create an application that prompts the user for a part number and quantity. Allow for the possibility of nonnumeric entries as well as out-of-range entries, and display the appropriate message when an error occurs. If no error occurs, display the message "Valid entry". Save the program as PartAndQuantityEntry.java.arrow_forward

Design an application that declares two AutomobileLoan objects and sets and displays their values.c. Design an application that declares an array of 20 AutomobileLoan objects. Prompt the user for data for each object, and then display all the values.d. Design an application that declares an array of 20 AutomobileLoan objects. Prompt the user for data for each object, and then pass the array to a method that determines the sum of the balances.arrow_forwardIn Python: Write a class named Pet, which should have the following data attributes: _ _name (for the name of a pet) _ _animal_type (for the type of animal that a pet is. Example values are 'Dog','Cat', and 'Bird') _ _age (for the pets age) The Pet class should have an _ _init_ _ method that creates these attributes. It should also have the following methods: set_nameThis method assigns a value to the _ _name field set_animal_typeThis method assigns a value to the _ _animal_type field set_ageThis method assignsa value to the _ _age field get_nameThis method assignsa value to the _ _name field get_animal_typeThis method assignsa value to the _ _animal_type field get_ageThis method assignsa value to the _ _age field Once you have written the class, write a program that creates an object of the class and prompts the user to enter the name, type and age of his or her pet. This data should be stored as the objects attributes.

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_forward

Price without tax: ... Price with tax: ... Reviews: - In your main method: 1. Print the sales tax (before creating any object). 2. Create two items. 3. Add three reviews to the two items. 4. Print the reviews of the two items to the console by invoking the printReviews method. 3. Change the sales tax to 0.13. 4. Print the details of each item by invoking the method printItemDetails.arrow_forward3- Create a class named Player with a default name as "player", a default level as 0, and a default class type of "fighter". Feel free to add any other attributes you wish! Create an instance method in the Player class called attack that takes another player as a parameter. This function should compare the level of the two players, and return whether the player won, lost, or tied. Finally create a loop that allows the user to input a name and a class type for two players; the level of both players should be determined at random (between 1 and 99). Print out the name and attributes of each player, and have the first player attack the second. Print whether the player won, lost, or tied. Ask if the user wants to try again.
