Personal Information Class:
Design a class that holds the following personal data: name, age, and phone number. Write appropriate accessor and mutator functions. Demonstrate the class by writing a program that creates three instances of it. One instance should hold your information, and the other two should hold your friend's or family member's information.
Problem: Employee and ProductionWorker Classes
Write a python class named ProductionWorker that is a subclass of the Employee class. The ProductionWorker class should keep data attributes for the following information:
• Shift number (an integer, such as 1, 2, or 3)• Hourly pay rateThe workday is divided into two shifts: day and night. The shift attribute will hold an integer value representing the shift that the employee works. The day shift is shift 1 and the night shift is shift 2. Write the appropriate accessor and mutator methods for this class. Once you have written the class, write a program that creates an object of the ProductionWorker class, and prompts the user to enter data for each of the object’s data attributes. Store the data in the object, then use the object’s accessor methods to retrieve it and display it on the screen
Note: The program should be written in python.
Sample Input/Output:
Enter the name: Ahmed Al-AliEnter the ID number: 12345Enter the department:…
True or FalseA base class reference variable can reference an object of any class that is derived from the base class.

- (Invoice Class) Create a class called Invoice that a hardware store might use to representan invoice for an item sold at the store. An Invoice should include four data members—a part number (type string), a part description (type string), a quantity of the item being purchased (typeint) and a price per item (type int). Your class should have a constructor that initializes the fourdata members. A constructor that receives multiple arguments is defined with the form:ClassName( TypeName1 parameterName1, TypeName2 parameterName2, ... )Provide a set and a get function for each data member. In addition, provide a member functionnamed getInvoiceAmount that calculates the invoice amount (i.e., multiplies the quantity by theprice per item), then returns the amount as an int value. If the quantity is not positive, it should beset to 0. If the price per item is not positive, it should be set to 0.

- Circle Class (Easy) Write a Circle class that has the following member variables: radius : a double The class should have the following member functions: Default Constructor: default constructor that sets radius to 0.0. Constructor: accepts the radius of the circle as an argument. setRadius: an mutator function for the radius variable. getRadius: an accessor function for the radius variable. getArea: returns the area of the circle, which is calculated as area = pi * radius * radius getCircumference: returns the circumference of the circle, which is calculated as circumference = 2 * pi * radius Step1: Create a declaration of the class. Step2: Write a program that demonstrates the Circle class by asking the user for the circle’s radius, creating Circle objects, and then reporting the circle’s area, and circumference. You should create at least two circle objects, one sets the radius to 0.0 and one accepts the radius as an…arrow_forwardNutritional information (classes/constructors) PYTHON ONLY Complete the FoodItem class by adding a constructor to initialize a food item. The constructor should initialize the name (a string) to "None" and all other instance attributes to 0.0 by default. If the constructor is called with a food name, grams of fat, grams of carbohydrates, and grams of protein, the constructor should assign each instance attribute with the appropriate parameter value. The given program accepts as input a food item name, fat, carbs, and protein and the number of servings. The program creates a food item using the constructor parameters' default values and a food item using the input values. The program outputs the nutritional information and calories per serving for both food items. Ex: If the input is: M&M's10.034.02.01.0 where M&M's is the food name, 10.0 is the grams of fat, 34.0 is the grams of carbohydrates, 2.0 is the grams of protein, and 1.0 is the number of servings, the output is:…arrow_forwardShiftSupervisor Class In a particular factory, a shift supervisor is a salaried employee who supervises a shift. In addition to a salary, the shift supervisor earns a yearly bonus when his or her shift meets production goals. Design a ShiftSupervisor class that extends the Employee class you created in Problem 1, The ShiftSupervisor class should have a field that holds the annual salary and a field that holds the annual production bonus that a shift supervisor has earned. Write one or more constructors and the appropriate accessor and mutator methods for the class. Demonstrate the class by writing a program that uses a ShiftSupervisor object. beginner code because this is an intro to java class.arrow_forward

- Account Class) Create an Account class that a bank might use to represent customers’ bank accounts. Include a data member of type intto represent the account balance. Provide a constructor that receives an initial balance and uses it to initialize the data member. Theconstructor should validate the initial balance to ensure that it’s greater than or equal to 0. If not, set the balance to 0 and display anerror message indicating that the initial balance was invalid. Provide three member functions. Member function credit should add anamount to the current balance. Member function debit should withdraw money from the Account and ensure that the debit amountdoes not exceed the Account’s balance. If it does, the balance should be left unchanged and the function should print a messageindicating "Debit amount exceeded account balance."
