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:

- Write a Java program: In the board game Scrabble, each tile contains a letter, which is used to spell words in rows and columns, and a score, which is used to determine the value of words. The point of this exercise is to practice the mechanical part of creating a new class definition: Write a definition for a class named Tile that represents Scrabble tiles. The instance variables should be a character named "letter" and an integer named "value". Write a constructor that takes parameters named letter and value, and initializes the instance variables. Create getters for both of the attributes. (No setters, so that a Tile is immutable.) Implement the .toString() and .equals methods for a Tile.Suppose you have some rupees in your hands. You can buy from this money something from that shop where billing is done in rupees. Suppose you go to such a shop for buying where only dollars are accepted, you cannot use your rupees there. This money is like a class. A class can fulfill only a particular requirement. It is not useful to handle different situations. Now suppose you have a credit card. In a shop, you can easily pay in rupees by using your credit card. If you go to another shop where dollars are accepted, you can also pay in dollars. The same credit card can be used to pay in pounds also. But how is this credit card paying in different currencies? Let’s understand it. Basically, a credit card is like an interface that performs several tasks. It is a thin plastic card that contains identification information such as your name, bank name, and perhaps some numbers. It does not hold any money physically. But here question is that how are shop keepers able to draw money from…Imagine a Car Parts and Accessories shop, which requires a software system to keep track of stock items and prices. The shop will sell different kinds of stock items. However, to start with, you have been tasked with designing and implementing a class called StockItem with the following properties. An instance (object) of the StockItem class represents a particular item which the shop sells, with a string representing fixed stock code, an integer representing variable quantity in stock and a double representing variable price of the stocked item. All these variables should be declared as private variables. The StockItemclass also contains a class variable (shared by all instances) of type string representing stock category which you can initialise as 'Car accessories'. A constructor that creates a Stock Item with the specified quantity, price and the stock code. All the appropriate ‘setters’ and ‘getters’ methods, including a getStockName() method which returns the string…
- In this challenge, we'll implement an Account class along with two derived classes, Savings and Current. Problem Statement# Write a code that has: ● A parent class named Account. ○ Inside it define: ■ a protected double member balance ■ public void Withdraw(double amount) ■ public void Deposit(double amount) ■ public void printBalance() ● Then, there are two derived classes ○ Savings class ■ has a private member interestRate set to 0.8 ■ Withdraw(double amount) deducts amount from balance with interestRate ■ Deposit(double amount) adds amount in balance with interestRate ■ printBalance() displays the balance in the account ○ Current class ■ Withdraw(double amount) deducts amount from balance ■ Deposit(double amount) adds amount in balance ■ printBalance() displays the balance in the account Input# ● In the Savings class, balance is set to 50000 in the parametrized constructor ● In the Current class, balance is set to 50000 in the parametrized constructor Output# Balance before…write program in java Create a class called with your Reg No, as Invoice18Arid876, 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 instance variables a part number (type String), a part description (type String),a quantity of the item being purchased (type int) and a price per item (double). Your class should have a constructor that initializes the four instance variables. Provide a set and a get method for each instance variable. In addition, provide a method named getInvoice Amount that calculates the invoice amount (i.e., multiplies the quantity by the price per item), then returns the amount as a double value. If the quantity is not positive, it should be set to 0. If the price per item is not positive, it should be set to 0.0. Write a test application named InvoiceTestYourName that demonstrates class Invoice’s capabilities.Write a class Account in Python that stores information about a bank account. (a) Your class should have at least three methods to manipulate any instance of the Account class: `withdraw()`, `deposit()`, and `__init__()`. (b) Your Account class should provide three class variables: - `interest_rate` set to 0.05 (5%) - `overdraft_limit` set to 500 (dollars), and - `overdraft_charge` set to 50 (dollars). These are values common to all accounts at this bank (i.e. all instances of this class). (c) Additionally, the Account class should create two instance variables: - `account_number` of the customer and - `balance` which is set to 0 dollars (it’s a new, empty account) These are values unique to each Account instance. (d) Allow your user to “overdraft” on their account. An overdraft occurs when money is withdrawn from a bank account and the available balance goes below zero. This allows a user to withdraw money on credit from the bank. The user should only be allowed to withdraw money up…
- For the 'The Chicken class' on the app intelliJ in java. The Chicken class must:• Define three fields called exactly name, pricePerKilo and inStock. The name field must be of type String, the pricePerKilo must be of type int (representing the cost per kilo in pence) and the inStock field must be of type boolean.• Initialise the three fields via a constructor that takes exactly two parameters. The first parameter must be of type String and the second parameter must be of type int. The first parameter must initialise the name field and the second must initialise the pricePerKilo field. The constructor must set the inStock field to true for all Chicken objects. There must be no parameter to the constructor for the inStock field.• Define getters for all three fields using the standard getter naming convention. In particular, note that the getter for the inStock field must be called getInStock rather than isInStock.• Define setters for the pricePerKilo and inStock fields using the standard…In this java assignment, we will be creating a pay stub for an employee using classes. Each class must be implemented into their own file, a total of 5 classes/files. We are going to implement the following classes: Employee – This class represents an employee. It needs the following fields exposed via getters and setters: Employee ID (we will need to make this unique, for now, just hard code it to 1). First name, Last name, Middle initial Address, City, Zip Phone, Email Hourly Rate PayPeriod – This class represents an employee’s payment information. An employee will eventually have more than one pay period. It must contain the following fields (exposed via getters and setters): Pay period Id (hard code it for now) Employee Id (who is this for) Start Date, End Date Number of hours PayrollManager – This class provides the functionality we need to compute and display our payroll. It should implement the following methods: double CalculateGrossPay (Employee, Payperiod) – This…Write a Java class called HotelRoom that represents a hotel room. The class will contain the following attributes: •RoomNo (int) •PhoneNumber (string) •Capacity (int) – Number of people that room can accommodate. •Grade (int) – Grade of room ranging 1-5, 5 being most valuable. Your class should have a constructor that takes a single parameter: RoomNo. The necessary accessors (i.e. get methods) and mutators (i.e. set methods) for class variables: Room number only accessor Phone number both mutator and accessor Capacity both mutator and accessor Grade both mutator and accessor 2.Write a Java class called Hotel that represents a hotel. The class will contain the following attributes: •Name (string) •ReceptionPhone (string) •RoomList (ArrayList of HotelRoom's) hotel class should have a constructor that takes two parameters: Hotel name and reception phone. The necessary accessors (i.e. get methods) and mutators (i.e. set methods) for class variables: Hotel name only accessor Reception phone…
- First, you need to design, code in Java, test and document a base class, Student. The Student class will have the following information, and all of these should be defined as Private: A first name (given name) A last name (family name/surname) Student number (ID) – an integer number (of type long) The Student class will have at least the following constructors and methods: (i) two constructors - one without any parameters (the default constructor), and one with parameters to give initial values to all the instance variables of Student. (ii) only necessary set and get methods for a valid class design. (iii) a reportGrade method, which you have nothing to report here, you can just print to the screen a message “There is no grade here.”. This method will be overridden in the respective child classes. (iv) an equals method which compares two student objects and returns true if they have the same student number (ID), otherwise it returns false. You may add other…Take the tax program from the last homework assignment and implement it using classes and objects instead. To do so, create a class definition for a class called Customer with attributes income and tax. It should also have a set method for income, and a calcTax() method to assign tax and return it. As a reminder, the tax is calculated as follows: Income Tax Due $0 - $50,000 5% $50,000-$100,000 $2,500 + 10% of (income > $50,000) > $100,000 $7,500 + 15% of (income > $100,000) Create a Customer object in main, have the user enter the income and assign this to the income variable of the Customer object, and then call the calcTax() method for the Customer object and print the tax due.write the following 3 classes for the Java program so that this program produces the sample output shown at the end of Main. ElectricCar: a vehicle with a limited range. So it must be a subclass of Vehicle, and it must implement LimitedRange. Thus it needs an instance variable for its range, and a travel method (required by Vehicle. Please use @Override) that outputs "Zoom!" if it has enough range to go the distance specified (and update its range). It must have a constructor with 3 arguments as called by main. It also needs a getCurrentRange method as required by LimitedRange (use @Override for this too). Motorboat: a vehicle with a limited range. So it is similar to ElectricCar, but it outputs "Wisshhh!" when it goes. Sailboat: a vehicle that doesn't have a limited range. So it is a subclass of Vehicle, but doesn't implement LimitedRange. It can go any distance, and outputs "Weee!" when it travels. Code: class Main { publicstaticvoid main(String[] args) { Vehicle[]…
