Design a class that implements the basic properties of a die. Consider the definition of the following class die.(Beginner) class die { public: die(); //Default constructor //Sets the default number rolled by a die to 1 void roll(); //Function to roll a die. //This function uses a random number generator to randomly //generate a number between 1 and 6, and stores the number //in the instance variable num. int getNum() const; //Function to return the number on the top face of the die. //Returns the value of the instance variable num. private: int num; }; a) Write the definitions of the functions to implement the operations for the class die. b) Write a program that uses the class die to roll 10 dice. (Use an array of size 10 to implement 10 dice.) The program prompts the user to enter the desired sum and the number of times the dice are to be rolled. The program outputs the number of times the desired sum was rolled. Test run your program to roll the 10 dice 10000 times with the desired…
public class Cat { private int age; public Cat (int a) { age = а; } public int getAge() { return a; } } Which of the following best explains why the getAge method will NOT work as intended? The instance variable age should be returned instead of a, which is local to the constructor. The variable age is not declared inside the getAge method. The getAge method should be declared as private. The getAge method should have at least one parameter.

1) Define a Person class containing two private attributes: last name, first name. Provide this class with a constructor allowing the initialization of its attributes and a method that displays the last name and first name of a person: void display (). 2) Define a Customer class inheriting from the Person class and having a private attribute: numidentity. Provide this class with a constructor allowing you to create a customer from their last name, first name and identity card number and a method: • void display() which displays the last name, first name and ID number of a customer. 3) Define an Owner class inheriting from the Person class and having two private attributes: name of the video club (nomclub), address of the club (adrclub). Provide this class with a constructor allowing to create a landlord from his name, his first name, the name of his video club, the address of his club and a method: • void display() who displays the name, first name, last name and address of his video…

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…
Assignment:  Write the class XXXX_Worker with constructors, accessors, mutuators, and a toString method. A Worker has a Worker Name and Number.  Write the class XXXX_ProductionWorker which is a subclass of Worker. The production worker has a shift number (values: 1 or 2) and an Hourly pay rate. A shift number of 1 means the day shift and 2 means the night shift.  Write the class XXXX_ShiftSupervisor which is a subclass of Worker. The shift supervisor is a salaried worker who supervises a shift. The shift supervisor has a yearly bonus field. The yearly bonus is earned at year end based on performance.  Write a class, XXXX_TestWorker, which does the following: Creates one Shift Supervisor object from information entered by the user. Creates an Array of Production Workers that can hold 3 objects. Itcreates3ProductionWorkerobjectsfrominformationenteredbytheuser Prints the information about each object in the format shown below using the toString methods of the…
1. Create abstract class Pet , which is the abstract super class of all animals.1. Declare an integer attribute called legs, which records the number of legs for this animal.2. Define a constructor that initializes the legs attribute.3. Declare an abstract method eat.4. Declare a concrete method walk that prints out something about how the animals walks (include the number of legs).2. Create the Dog class that implements Pet class.1. This class must include a String attribute to store the name and food of the pet2. Define a default constructor that calls the super class constructor to specify that all dogs have 4 legs and name.3. override the eat and walk method.3. Create the Cat class that Implements Pet class.1. This class must include a String attribute to store the name of the pet, and a string to save food .2. Define a constructor that takes one String parameter that specifies the cat's name. This constructor must also call the super class constructor to specify that all cats have…
5. Define a class Student to create Student Objects. The class defines two variables for its objects: name (String ) and average (double). The class provides a constructor with arguments and includes the following object methods to do the following: - public void print() : prints the Student data - public void setAverage(double newAvergae): sets the student average with a new value. Define a class StudentTest In the main method, create three student objects (Ali, Rami, Khalid) with initial average 60 for each one. Call the setAverage method on each created student to change their average with a randomly value (hint: use Math.random( ) method to generate average value in range [0..100]). - Print the name of the student who's the maximum average. hint: you should compare between the Student objects according to their average.
Declare and implement an Employee class for the payroll system: 4.1 Declare a class that meets the scenario requirements. Ensure that the method that compares the two objects receives objects of the Employee class and returns an int. 4.2 Implement the class methods on the same code as the class declaration 4.3 Write a main function in the same code and test the payroll system. Use the parameterised constructor to create the two objects and then test the method that compares the two and display a message that states which employee earns more than which employee.
