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:
Step by step
Solved in 2 steps with 1 images
- Write a class definition that creates a class called leverage with one private data member, crowbar, of type int and one public function whose declaration is void pry(). Opp Java1- Create a class SchoolKid that is the base class for children ar aschool . It should have attributes of the child’s name and age ,the name of the child’s teacher ,and the greeting. It should haveappropriate accessor and mutator methods for each of the attributes. Derive a class ExaggeratingKid from schoolkid , as described above . The new class should override the accessor method for the age , reporting the actual plus 2. It also should override the accessor for the greeting ,returning the child’s greeting concatenated with the words “I am the best”.PLZ help wiith the following: IN JAVA If an inner class contains non static members, then the class name must be modified by the keyword: Final Static Void Protected
- 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.Q2: Using C# - Class Account declares two instance variables, name and balance. Class SavingAccount derives from Account and declares an instance variable minBalance of type double. Write the constructor for class SavingAccount, which calls the base class constructor to initialize base class variables and variable minBalance.Consider the definition of the following class: (1, 2, 3, 5, 7) a. Give the line number containing the constructor that is executed in each of the following declarations. b. Write the definition of the constructor in Line 4 so that the instance variables are initialized to " ", " ", " ", 0, 0.0, and 0.0, respectively. c Write the definition of the constructor in Line 5 so that the string instance variables are initialized to"", and the other instance variables are initialized according to the parameters. Instance variables quantitieslnStock, price, and discount must be nonnegative. d. Write the definition of the constructor in Line 6 so that the instance variables productName and manufacturer are initialized to the empty string, instance variable id is initialized according to the first parameter, and the remaining instance variables are initialized according to the last three parameters. Instance variables quantitieslnStock, price, and discount must be nonnegative. e. Write the definition of the constructor in Line 7 so that the instance variables are initialized according to the parameters. Instance variables quantitieslnStock, price, and discount must be nonnegative.
- Mark the following statements as true or false. The member variables of a class must be of the same type. (1) The member functions of a class must be public. (2) A class can have more than one constructor. (5) A class can have more than one destructor. (5) Both constructors and destructors can have parameters. (5)Using classes, design an online address book to keep track of the names, addresses, phone numbers, and dates of birth of family members, close friends, and certain business associates. Your program should be able to handle a maximum of 500 entries. Define a class addressType that can store a street address, city, state, and ZIP code. Use the appropriate functions to print and store the address. Also, use constructors to automatically initialize the member variables. Define a class extPersonType using the class personType (as defined in Example 10-10, Chapter 10), the class dateType (as designed in this chapters Programming Exercise 2), and the class addressType. Add a member variable to this class to classify the person as a family member, friend, or business associate. Also, add a member variable to store the phone number. Add (or override) the functions to print and store the appropriate information. Use constructors to automatically initialize the member variables. Define the class addressBookType using the previously defined classes. An object of the type addressBookType should be able to process a maximum of 500 entries. The program should perform the following operations: Load the data into the address book from a disk. Sort the address book by last name. Search for a person by last name. Print the address, phone number, and date of birth (if it exists) of a given person. Print the names of the people whose birthdays are in a given month. Print the names of all the people between two last names. Depending on the users request, print the names of all family members, friends, or business associates.In Chapter 10, the class clockType was designed to implement the time of day in a program. Certain applications, in addition to hours, minutes, and seconds, might require you to store the time zone. Derive the class extclockType from the class clockType by adding a member variable to store the time zone. Add the necessary member functions and constructors to make the class functional. Also, write the definitions of the member functions and the constructors. Finally, write a test program to test your class.
- Use JAVA - This task helps you understand how constructors work in inheritance Create a superclass, called SuperClass. Create a constructor for it. Inside the constructor, let it print “this is super class.” Create a childclass of SuperClass, called ChildClass. Create a constructor for it. Inside the constructor, let it print “this is child class.” Create a main function and create a new object for ChildClass. Observe what’s printed in console. What will happen if you have a default constructor without parameters in addition to the one with parameters?How many default constructors can a class have? a. A class cannot have a default constructor. b. only one c. as many as it needs d. one or more, but fewer than threeImplement “SoftwareEngineer” and “CheifEngineer” class derived from “Employee” class with necessary properties so that the expected output is generated. Do not change any given code. # Write your codes here.# Do not change the following lines of code.sw1 = SoftwareEngineer("Bob","Software Engineer",40,1200)print('1.------------------------------------')sw1.calculateWeeklyIncome()print('2.------------------------------------')print(sw1)print('3.------------------------------------')sw2 = SoftwareEngineer("Carol","Software Engineer",45,1200,5)print('4.------------------------------------')sw2.calculateWeeklyIncome()print('5.------------------------------------')print(sw2)print('6.------------------------------------')print(Employee.employeeInfo)print('7.====================================')ce1 = ChiefEngineer("John","Chief…
