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:
Q1) Write the Code the following scenario.
Write an abstract function named receivePay in interface with return type double and no parameters. Write another incomplete function, name Show with return type void and an argument of type int in that interface. Build a class with name Bill that implements the above interface. Bill class with name BillId , itemsquantity and itemsprice with proper datatypes with private access . Define two constructors,one default and other is parameterized to initialize the class members . Now receivePay has to beimplemented in such a way that its displays product of itemsquantity and itemsprice and Display function will display the BillId.Can we do same task with abstract class instead of interface?

- Part (1) Define a class with the following specifications: The class name is HeightWeightRatio with three private data members: gender (String as male or female in any letter case), height (double in cm), and weight (double in kg). b. a. Write a constructor that accepts gender, height and weight as input parameters to initializes the private data members. C. Provide an accessor (get) method and a mutator (set) method for the height data member. d. Define a public method called checkRatio( ) which checks the height/weight ratio and returns the decision as Boolean. The height/weight ratio decision is checked as the following: Male: Acceptable when weight is between (height-105) and (height-95); otherwise, is not acceptable Female: Acceptable when weight is between (height-100) and (height-90); otherwise, is not acceptable е. Define a public method called showDetails() to show all details as in the following sample: Gender is Male Height is 170 CM Weight is 74 KG Part (2) Write a Java…objective of the project: Implement a class address. An address has a house number street optional apartment number city state postal code. All member variables should be private and the member functions should be public. Implement two constructors: one with an apartment number one without an appartment number. Implement a print function that prints the address with the street on one line and the city, state, and postal code on the next line. Implement a member function comesBefore that tests whether one address comes before another when the addresses are compared by postal code. Returns false if both zipcodes are equal. Use the provided main.cpp to start with. The code creates three instances of the Address class (three objects) to test your class. Each object will utilize a different constructor. You will need to add the class definition and implementation. The comesBefore function assumes one address comes before another based on zip code alone. The test will also return…Part (1) Define a class with the following specifications: The class name is HeightWeightRatio with three private data members: gender (String as male or female in case), height (double in cm), and weight (double in kg).

Create a Student class that implements the Person interface. As well as storing the students name and email, also store their course grade (e.g A, B, C) in a member variable. The grade should be accessible via a getGrade method. For the implementation of getDescription return a message along the lines of “A C grade student”, substituting the students actual grade.2. Create a Lecturer class that implements the Person interface. This class should also store the subject that the lecturer teaches. Add a getSubject method, and implement getDescription so that it returns a suitable message, e.g. “Teaches Biology”.3. Create a third class, Employee that implements the interface. This should also store the name of the department the Employee works in (available via getDepartment). Again, getDescription should return a suitable message.1) Define a Person class containing two private attributes: last name, first name. Provide this class with a constructor allowing the initialization of its attributes and a method that displays the last name and first name of a person: void display (). 2) Define a Customer class inheriting from the Person class and having a private attribute: numidentity. Provide this class with a constructor allowing you to create a customer from their last name, first name and identity card number and a method: • void display() which displays the last name, first name and ID number of a customer. 3) Define an Owner class inheriting from the Person class and having two private attributes: name of the video club (nomclub), address of the club (adrclub). Provide this class with a constructor allowing to create a landlord from his name, his first name, the name of his video club, the address of his club and a method: • void display() who displays the name, first name, last name and address of his video…

- Use C++ Create a class called Fruit. Add one member variables name. Add only one getter function for the name. The get function returns name. Implement a constructor that expects name value and assigns it to the member variable. This class doesn't have an empty constructor. Create a subclass of Fruit named CitrusFruit. The CitrusFruit class has two member variables weight and color. Add a constructor which expects weight and name and color.Pass name to the base constructor and set weight and color to it's member variable. Write a program that has an array of 3 Fruits, and an array of 3 CitrusFruits. Feel free to give the name , weight and color to the object as your choice. Use loops to print out the array properties to the terminal screen.Create a class Student that contains information about a student’s name, semester, roll no, and date of admission. To store the date of admission, use a structure to define date. Providea. a no-argument constructor for initializing the values of data members to some defaults. b. a 4-argument constructor to initialize the data members sent from the calling function at the time of creation of an object (date should be sent from outside in the form of a date object). c.
