C++Question 3: Please answer the following questions.1. Define a class named "BoolVariable" that manages a variable name (string)and a boolean value (true or false). It should not have default constructor.The class must at least provide the following methods:o toString() method that can return a string in the following format:variable-name(variable-boolean-value) such as isSuccessful(true)o containsIgnoreCase() that accepts a search string and it will return true ifits variable name contains that string (case-insensitive) and falseotherwise.Show how this class being used to create objects and call all its methods and showhow they work.2. Define a new exception class named "VarNameException" that must inheritfrom the C++ runtime error class. This class will capture the error case for avariable name when it is empty, only blanks or starting with a number.For example, if the user tries to create with a variable name of ","Iname", it will generate an exception and this class should capture the reasonand the error value.*, or3. Write a new class named "IntVariable" that must inherit from the"BoolVariable" class. This class manages a variable name (string) and a value(integer). Please note that this class must make use of inheritance.The class must at least provide the following methods:o toString() method that can return a string in the following format:variable-name(variable-integer-value) such as count(100)o isGreater() method that accepts another IntVariable object and returns trueif its own integer value is greater than the integer value of the given objectand false otherwise.Its constructor will generate exception with the right error informationusing the VarNameException class whenever it is given a variable namethat can be empty, all blanks or starting with a number.

Java - Access Specifiers Create a class named Circle that has attributes radius, area, and circumference and make the attributes private. Make a public method that sets the radius and a method that prints all attributes. Ask the user input for radius. Note: Use the PI from the math functions Inputs A line containing an integer 10 Sample Output Radius: 20 Area: 1256.64 Circumference: 125.66
5. Write a class named Point that contains: . public int field named a. public int field named b. public int field named c. public default constructor that assigns 0 to all its fields. public copy constructor. - public assignment operator. . . . public empty destructor. public string constant method named ToString() that takes no parameters. It returns a string in the format (z,y,z) where z, y, and are the values of a, b and respectively.
It is customary that we write this method to return a string representation of objects in a class. constructor mutator toString accessor
java Assignment Description: Write a class named Car that has the following fields: The yearModel field is an int that holds the car’s year model. The make field references a String object that holds the make of the car. The speed field is an int that holds the car’s current speed. In addition, the class should have the following constructor and other methods. The constructor should accept the car’s year and make as arguments. These values should be assigned to the object’s yearModel and make fields. The constructor should also assign 0 to the speed field. Constructor: The constructor should accept no arguments. Constructor: The constructor should accept the car’s year as argument.Assign the value to the object’s yearModel. No need to assign anything to the make and assign 0 to speed. Appropriate mutator methods should set the values in an object’s yearModel, make, and speed fields. Appropriate accessor methods should get the values stored in an object’s yearModel, make, and…

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.

Question - Create a class named Pizza with the following data fields: description - of type String price - of type double The description stores the type of pizza (such as sausage and onion). Include a constructor that requires arguments for both fields and a method named display to display the data. For example, if the description is 'sausage and onion' and the price is '14.99', the display method should output: sausage and onion pizza Price: $14.99 Create a subclass named DeliveryPizza that inherits from Pizza but adds the following data fields: deliveryFee - of type double address - of type String The description, price, and delivery address are required as arguments to the constructor. The delivery fee is $3 if the pizza ordered costs more than $15; otherwise it is $5. Code that is not accepted - class DeliveryPizza extends Pizza { private double deliveryFee; private String address; public DeliveryPizza(String desc, double price, double deliveryFee, String address){…
2. The MyInteger Class Problem Description: Design a class named MyInteger. The class contains: n [] [] A private int data field named value that stores the int value represented by this object. A constructor that creates a MyInteger object for the specified int value. A get method that returns the int value. Methods isEven () and isOdd () that return true if the value is even or odd respectively. Static methods isEven (int) and isOdd (int) that return true if the specified value is even or odd respectively. Static methods isEven (MyInteger) and isOdd (MyInteger) that return true if the specified value is even or odd respectively. Methods equals (int) and equals (MyInteger) that return true if the value in the object is equal to the specified value. Implement the class. Write a client program that tests all methods in the class.
