2019 AP® COMPUTER SCIENCE A FREE-RESPONSE QUESTIONS 2. This question involves the implementation of a fitness tracking system that is represented by the StepTracker class. A StepTracker object is created with a parameter that defines the minimum number of steps that must be taken for a day to be considered active. The StepTracker class provides a constructor and the following methods. addDailySteps, which accumulates information about steps, in readings taken once per day activeDays, which returns the number of active days averageSteps, which returns the average number of steps per day, calculated by dividing the total number of steps taken by the number of days tracked The following table contains a sample code execution sequence and the corresponding results. Statements and Expressions Value Returned Comment (blank if no value) StepTracker tr StepTracker(10000); Days with at least 10,000 steps are considered active. Assume that the parameter is positive. new tr.activeDays () ; No…
T/F: Instance variables are shared by all the instances of the class. T/F: The scope of instance and static variables is the entire class. They can be declared anywhere inside a class. T/F: To declare static variables, constants, and methods, use the static modifier.
It is possible for a class to have more than one constructor.A) This is correct. B) The answer is False.
:Define and implement class Employee. This class should contain the following fields: first name, last name, employee id, hourly pay. This class should contain getters and setters for all its attributes. This class also needs at least one constructor. Implement method computePay() in this class. This method should accept an integer number of hours the employee worked as an input argument and return a floating point value indicating the pay the employee earned. If the number of hours is invalid (e.g. a negative number) this method should throw NumberFormatException. If the number of hours is over 40 then this method should throw a custom exception named TooManyHoursWorkedException. Remember that you will have to define your own exception class for this. Save this class and its definition into a file named Employee.java. Define and implement class EmployeeTest.This class should implement main() method. In the body of the main() method you should create an instance of Employee with the…

Python Programming Questions (OOP): Question 2: i) Write a complete class called GasPump to represent a gas pump. The class should have a constructor to set the amount of available gas supply (in litres) and the price of gas per litre. The class should include: -An accessor and a mutator to set and get the gas price. -An accessor to get the current amount of gas supply. -A method to add fuel to the gas supply. Note that the maximum capacity of the pump is 5000 litres. If we try to add too much fuel, once the maximum capacity is reached, no more fuel can be added. -A method that sells a specific amount of gas. This method should reduce the supply of available gas by the amount sold and return the total cost of the gas sold. If the supply of the available gas is less than the amount requested, then only the existing supply should be sold. ii) Using the class defined in part (i), add a driver that will: - Create an object called ‘shell’ of the class GasPump and initializes it…
this is java problem I try bu can't solve can i get help thanks Sanchez Construction Loan Co. makes loans of up to $100,000 for construction projects. There are two categories of Loans—those to businesses and those to individual applicants. Write an application that tracks all new construction loans. The application also must calculate the total amount owed at the due date (original loan amount + loan fee). The application should include the following classes: • Loan —A public abstract class that implements the LoanConstants interface. A Loan includes a loan number, customer last name, amount of loan, interest rate, and term. The constructor requires data for each of the fields except interest rate. Do not allow loan amounts greater than $100,000. Force any loan term that is not one of the three defined in the LoanConstants class to a short-term, 1-year loan. Create a toString() method that displays all the loan data. • LoanConstants—A public interface class. LoanConstants includes…

Doggie Day Care Given the TestDog class below, write a Dog class that will pass the tests contained in our test class. Do NOT change anything in our test class! Your Dog class must provide the following methods to adequately pass our tests:* __init__ (takes a string name of dog, int age and Boolean indicating a purebred or not),* is_purebred (returns True or False depending on if the dog is a purebred) * clone (makes a non-mutated copy of the current object)* __str__ returns a string representation of the object* __eq__ returns True or False when comparing two instances of the Dog class import unittest from coding import Dog class TestDog(unittest.TestCase):''' class to test all the methods of the Dog class imports from TestCase Compares inputs and expected outputs with all SimpleFraction methods: * __init__,* is_purebred,* clone (makes a non-mutated copy of the current object) * __str__, represent the Dog as a string * __eq__, compare current object with another Dog.

Employee Class (Medium) Write a class named Employee that has the following member variables: name. A string that holds the employee’s name. idNumber. An int variable that holds the employee’s ID number. department. A string that holds the name of the department where the employee works. position. A string that holds the employee’s job title. The class should have the following constructors: A constructor that accepts the following values as arguments and assigns them to the appropriate member variables: employee’s name, employee’s ID number, department, and position. A constructor that accepts the following values as arguments and assigns them to the appropriate member variables: employee’s name and ID number. The department and position fields should be assigned an empty string (""). A default constructor that assigns empty strings ("") to the name, department, and position member variables, and 0 to the idNumber member variable. Write appropriate mutator functions that…
