- A(n) ____________ is one instance or variable of a class.arrow_forwardParent Class: Food Write a parent class called Food. A food is described by a name, the number of grams of sugar (as a whole number), and the number of grams of sodium (as a whole number). Core Class Components For the Food class, write: the complete class header the instance data variables a constructor that sets the instance data variables based on parameters getters and setters; use validity checking on the parameters where appropriate a toString method that returns a text representation of a Food object that includes all three characteristics of the food Class-Specific Method Write a method that calculates what percent of the daily recommended amount of sugar is contained in a food. The daily recommended amount might change, so the method takes in the daily allowance and then calculates the percentage. For example, let's say a food had 6 grams of sugar. If the daily allowance was 24 grams, the percent would be 0.25. For that same food, if the daily allowance was 36 grams, the…arrow_forwardProgramming Language= PYTHON 3. Personal Information Class Design a class that holds the following personal data: name, address, age, and phone number. Write appropriate accessor and mutator methods. Also, write a program that creates three instances of the class. One instance should hold your information, and the other two should hold your friends’ or family members’ information. My information: Name: John Doe Address: 111 My Street Age: 22 Phone Number: 555-555-1281 Mom's information: Name: Mom Address: 222 Any Street Age: 52 Phone Number: 555-555-1234 Sis's infomation: Name: Jane Doe Address: 333 Her Street Age: 20 Phone Number: 555-555-4444 Dad's information: Name: Dad Address: 222 Any Street Age: 56 Phone Number: 555-254-5611arrow_forward
- (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. Write a test program that demonstrates class Invoice’s capabilitiesarrow_forward(Rational Numbers) Create a class called Rational for performing arithmetic with fractions. Write a program to test your class. Use integer variables to represent the private instance variables of the class—the numerator and the denominator. Provide a constructor that enables an object of this class to be initialized when it's declared. The constructor should store the fraction in reduced form. The fraction 2/4 is equivalent to 1/2 and would be stored in the object as 1 in the numerator and 2 in the denominator. Provide a no-argument constructor with default values in case no initializers are provided. Provide public methods that perform each of the following operations: a) Add two Rational numbers: The result of the addition should be stored in reduced form. Implement this as a static method. b) Subtract two Rational numbers: The result of the subtraction should be stored in reduced form. Implement this as a static method.…arrow_forwardTrue or FalseA base class reference variable can reference an object of any class that is derived from the base class.arrow_forward
- 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:…arrow_forward(Date Class) Create a class called Date that includes three pieces of information as datamembers—a month (type int), a day (type int) and a year (type int). Your class should have a constructor with three parameters that uses the parameters to initialize the three data members. For thepurpose of this exercise, assume that the values provided for the year and day are correct, but ensurethat the month value is in the range 1–12; if it isn’t, set the month to 1. Provide a set and a get function for each data member. Provide a member function displayDate that displays the month, dayand year separated by forward slashes (/). Write a test program that demonstrates class Date’s capabilities.arrow_forwardClass member methods (choose the best answer) A.) defines what the class can do B.) must return a value or void C.) are set to private by default D.) Is also called a function E.) all of the abovearrow_forward
- Nutritional 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_forwardA class may have several constructors and it is called __________.arrow_forwardBank Account Class Part (1) Define a class with the following specification:(a) The class name is BankAccount and it has two private variables: fullName (String) and balance (double). (b) Write a constructor that initializes fullName and balance variables. If balance is negative, then set it to 0.0 and print the message “Invalid balance. Balance is set to 0.0”. (c) Provide a set and get methods to balance variable. In set method, if the supplied balance (parameter) is negative print an invalid message and do not change the balance.(d) Write a method deposit() that has one double input parameter called amount. The method adds amount to the current balance.(e) Write a method withdraw() that has one double input parameter called amount. The method subtracts amount from the current balance.(f) Write method printInfo() that displays the full name on a single line followed by the balance on the next line. Part (2) Write a Java application to test the class you defined in Part (1):(a) Ask…arrow_forward
