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:

- 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…#employee.py class Employee: def__init__(self,Emp_name,Emp_id): self.__Emp_name=Emp_name self.__Emp_id=Emp_id defset_Empname(self,Emp_name): self.__Emp_name=Emp_name defset_Empid_number(self,Emp_id): self.__Emp_id=Emp_id defget_Empname(self): returnself.__Emp_name defget_Empid_number(self): returnself.__Emp_id class ProductionWorker(Employee): def__init__(self,Emp_name,Emp_id,Emp_shift, Emp_pay_rate): Employee.__init__(self,Emp_name,Emp_id) self.__Emp_shift=Emp_shift self.__Emp_pay_rate=Emp_pay_rate defset_Empshift_number(self,Emp_shift): self.__Emp_shift=Emp_shift defset_Emppay_rate(self,Emp_pay_rate): self.__Emp_pay_rate=Emp_pay_rate defget_Empshift_number(self): returnself.__Emp_shift defget_Emppay_rate(self): returnself.__Emp_pay_rate def main(): Employee_name='' Employee_id='' Employee_shift=0 Employee_pay=0.0 Employee_name=input('Enter the employee name: ') Employee_id=input('Enter the employee ID number: ') Employee_shift=int(input('Enter the employee shift number: '))…C# languageWrite a program to create a class employee, it consist of ID, name, department and address. All employees belongs to “Computer Science” department and it can never be changed by any means. Employee ID is initialized only once when Employee object is created, any further attempt to change ID should be failed. Class must have a 3 parameterized constructor to set values and two methods: print(): to display all the data of a particular employee totalObjects(): to count and print total number of objects that has been created In Main(), create atleast two objects of employee class, display their records by calling print() function and also print the total number of objects that has been created. [this question is continued on next page] Sample Main Method: static void Main(string[] args) { Employee obj1 = new Employee(1, "Zubair", "Karachi"); obj1.print(); Employee obj2 = new Employee(2, "Nabeel", "Islamabad"); obj2.print();…
- Create a Class called Transaction with: instance variables: stock - your stock class type - char -> b or s (buy/sell) quantity - can be fractional price - buy/sell price when - LocalDate constructors: constructor with parameters for stock, type and quantity. - sets the price from the stock price instance variable - sets when from LocalDate getters and setters for each instance variableLibrary Information System Design and Testing Library Item Class Design and TestingDesign a class that holds the Library Item Information, with item name, author, publisher. Write appropriate accessor and mutator methods. Also, write a tester program(Console and GUI Program) that creates three instances/objects of the Library Items class. Extending Library Item Class Library and Book Classes: Extend the Library Item class in (1) with a Book class with data attributes for a book’s title, author, publisher and an additional attributes as number of pages, and a Boolean data attribute indicating whether there is both hard copy as well as eBook version of the book. Demonstrate Book Class in a Tester Program (Console and GUI Program) with an object of Book class.Temp Class - Create Temp class whos job is to hold a temp in degrees F and gives methods to get the temp in F, Celsius, and Kelvin. The class should follow the instance variable (field): ftemp (double type that holds F temp)Follow these methods with the class.. Constructor --Will accept Fahrenheit temperature as a double to store it in the ftemp field. setFahrenheit - The setFahrenheit method accepts a Ftemperature as a doubleto stores it in the ftemp field. getFahrenheit - Returns the value of the ftemp field, as a Fahrenheit temperature (no conversion required). getCelsius - Returns the value of the ftemp field converted to Celsius. [C e l s i u s = ( 5.0 / 9.0 ) × ( F a h r e n h e i t − 32 )] getKelvin - Returns the value of the ftemp field converted to Kelvin. [K e l v i n = ( ( 5.0 / 9.0 ) × ( F a h r e n h e i t − 32 ) ) + 273] Exemplify the temp class by writing a (test) program that is separate and promotes users for an F Fahrenheit temp. The program must create an…
- True or False ___(37) If class B is a child class of class A, when you create an object from class B, both the constructor of class B and the constructor from the class A are used to create the object. ___(38) An Interface can have a method that contains an empty method body. ___(39) An object can have another object as its private variable.True or False An interface can be used to define a set of methods that a class must implement.Design a class named StopWatch. The class contains:■■ Private data fields startTime and endTime with getter methods.■■ A no-arg constructor that initializes startTime with the current time.■■ A method named start() that resets the startTime to the current time.■■ A method named stop() that sets the endTime to the current time.■■ A method named getElapsedTime() that returns the elapsed time for thestopwatch in milliseconds.Draw the UML diagram for the class then implement the class. Write a test programthat measures the execution time of sorting 100,000 numbers using selection sort.
