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:

- Focus on classes, objects, methods and good programming style Your task is to create a BankAccount class(See the pic attached) The bank account will be protected by a 4-digit pin number (i.e. between 1000 and 9999). The pin should be generated randomly when the account object is created. The initial balance should be 0. get_pin()should return the pin. check_pin(pin) should check the argument against the saved pin and return True if it matches, False if it does not. deposit(amount) should receive the amount as the argument, add the amount to the account and return the new balance. withraw(amount) should check if the amount can be withdrawn (not more than is in the account), If so, remove the argument amount from the account and return the new balance if the transaction was successful. Return False if it was not. get_balance() should return the current balance. Finally, write a main() to demo your bank account class. Present a menu offering a few actions and perform the action the user…T/F: Instance variables are shared by all the instances of the class. T/F: The scope of instance and static variables is the entire class. They can be declared anywhere inside a class. T/F: To declare static variables, constants, and methods, use the static modifier.Objectives: At the end of this activity, you should be able to: define classes implement polymorphism and inheritance instantiate an object array apply Exception to all input validations create a Java application for multiple users Procedure: Create a NetBeans project for this activity. The project name should be as follows: o Client (the main class that contains the main method and the implementation of the main menu) o Credit (the class where attributes and methods are defined) The class names to be created are the following: o Client<your_last_name> Ex. ClientBlancoo Credit<your_last_name> Ex. CreditBlanco All class names must be suffixed with your last name. Note that the object to be instantiated in the main method is an object array.For example: CreditBlanco [ ] cb = new CreditBlanco [100]; Compress the NetBeans project into .rar or .zip format and then upload to the link provided in the LMS. Only NetBeans project compressed in .rar or .zip format will be…
- java When we create an object of a class, the object's instance variables are automatically initialized with its default values without us writing code in any constructor. Choose one of the options:TrueFalsejava 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…The reference this can be used to refer to an object or to invoke another constructor of the same class.

Be sure your Inventory class defines the private data fields, at least one constructor, accessor and mutator methods, method overloading (to handle the data coming into the Inventory class as either a String and/or int/float), as well as all of the methods (methods to calculate) to manipulate the Inventory class (object). The data fields in the Inventory class include the inventory product number (int), inventory product description (String), inventory product price (float), inventory quantity on hand (int), inventory quantity on order (int), and inventory quantity sold (int). The Inventory class (java file) should also contain all of the static data fields, as well as static methods to handle the logic in counting all of the objects processed (counter), as well as totals (accumulators) for the total product inventory and the total product…Pyhton Code: Create a Pizza class which stores information about a single pizza. It contains the following: -Instance variables to store the size of the pizza (small, medium or large), (1)the number of cheese toppings, (2)the number of pepperoni toppings, and the (3) number of mushroom toppings. - Constructor: that takes four arguments and sets all of the corresponding instance variables and that initializes all instance variables to the zero of their type. - Methods to get (accessor) and set (mutator) each instance variable individually. - A method called calcCost() that returns the cost of the pizza. Pizza cost is determined by: Small: $10 + $2 per topping Medium: $12 + $2 per topping Large: $14 + $2 per topping. -A method which returns a string for the pizza size, quantity of each topping, and the pizza cost as calculated by the following example, a large pizza with 1 cheese, 2 pepperoni and 1 mushroom toppings should cost $22 (you can overwrite __str__).
