- It is possible for a class to have more than one constructor.A) This is correct. B) The answer is False.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.
- :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…Please help with the following: C# .NET change the main class so that the user is the one that as to put the name Write a driver class (app) that prompts for the person’s data input, instantiates an object of class HeartRates and displays the patient’s information from that object by calling the DisplayPatientRecord, method.

- Mark the following statements as true or false. The member variables of a class must be of the same type. (1) The member functions of a class must be public. (2) A class can have more than one constructor. (5) A class can have more than one destructor. (5) Both constructors and destructors can have parameters. (5)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…Please help with the following: C# .NET change the main class so that the user is the one that as to put the name a driver class that prompts for the person’s data input, instantiates an object of class HealtProfile and displays the patient’s information from that object by calling the DisplayHealthRecord, method.

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.
