OOPs
In today's technology-driven world, computer programming skills are in high demand. The object-oriented programming (OOP) approach is very much useful while designing and maintaining software programs. Object-oriented programming (OOP) is a basic programming paradigm that almost every developer has used at some stage in their career.
Constructor
The easiest way to think of a constructor in object-oriented programming (OOP) languages is:
super is a special keyword that directs the compiler to invoke the superclass methods.

The class should provide accessor and mutator for each property The class should override the __str__ method to return the state of the object. Create a child class called student which has a property named graduation year (graduation_year) and major. Provide accessor and mutator for each property of its own It inherits all the properties and methods of the person parent class as well.

Create an object of the person class and print…There must be classes and objects.Attributes are of type publicUse one or two constructors.Write a program in Object Oriented Java language that adds and subtracts two polynomials of the form ax2 +bx+c
- Python Programming- Invoice Class Introduction: Requires creating classes and instantiating objects from created class Instructions: Create a class called Invoice that a hardware store might use to represent an invoice for an item sold at the store. An Invoice should include four pieces of information as data attributes--a part number (a string), a part description (a string), a quantity of the item being purchased (an int.) and a price per item (a Decimal). Your class shold have an __init__ method that intializes the four data ttributes. Provide a property for each data attribute. The quantity and price per item should each be non-negative--use validation in the properties for these data attributes to ensure that they remain valid. Provide a calculate_invoice method that returns the invoice amount (that is, multiplies the quantity by the price per item). Demonstrate class Invoice's capabilities. Once you have written the class, write a program that creates two Invoice Objects to hold…The .NET Framework provides a class named __________, which contains numer- ous methods that are useful for performing advanced mathematical operations. a. Math b. Calc c. Trig d. LinqFocus on classes, objects, methods and good programming style. Program has to be written in basic python. Your task is to create a BankAccount class.

For example, if birthmonth=3, birthday=22, birthyear=2000, it should return the String "3/22/2000" Create a public method called verifySSN that takes in a String parameter and returns a boolean. It will check the parameter against the person's SSN and return true or false based on whether they match.
- Python Class and Objects Create a class named "Account" and “Bank” The class “Account” should have a parameter of id - integer type name - string type balance - float type # (Optional) You may add more parameters for your convenience 3. Create a method for “Account” class: checkBalance(self) - this will show the Account's remaining balance or money withdraw(self, amount) - this will withdraw an amount from the Account deposit(self, amount) - this will deposit an amount from the Account # (Optional) You may add more methods like sendMoney() etc. 4. Create a method for “Bank” class: addAccount(self, account) – used to register an account to the bank # (Optional) You may add more methods for your convenience 4.
