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 3 steps
- Java program Make a class Employee with a name and salary. Make a class Manager inherit from Employee. Add an instance variable, named department, of type String. Supply a method toString that prints the manager’s name, department, and salary. Make a class Executive inherit from Manager. Supply appropriate toString methods for all classes. Supply a test program that tests these classes and methods.Given the following class: public class Student { private long ID; private String name; } Write two constructor methods for the Student class, one without parameters and the other with.1/ Write a BankAccountTester class whose main method constructs a bank account, deposits $1,000, withdraws $500, withdraws another $400, and then prints the remaining balance. Also print the expected result 2/ Implement a class Employee. An employee has a name (a string) and a salary (a double). Provide a constructor with two arguments public Employee(String employeeName, double currentSalary) and methods public String getName() public double getSalary() public void raiseSalary(double byPercent) These methods return the name and salary, and raise the employee's salary by a certain percentage. Sample usage: Employee harry = new Employee("Hacker, Harry", 50000); harry.raiseSalary(10); // Harry gets a 10 percent raise Supply an EmployeeTester class that tests all methods. 3/Implement a class Car with the following properties. A car has a certain fuel efficiency (measured in miles/gallon or liters/km—pick one) and a certain amount of fuel in the gas tank. The efficiency is specified in…
- Write a class Point with instance variables as: xCoordinate(int) and yCoordinate(int). Write public instance methods (getters & setters) for each instance variable. Now, write a class Circle with private instance variables as radius and Pi (value is 3.14). Write public setter, getter for radius, Area method for calculating Area, Draw method for radius. Formula for calculating area=pi*r^2 Formula for calculating radius= Math.sqrt (xCordinate^2+yCordinate^2) a. Extend a Circle class from Point class such as Class Circle extends Pointb. Write a Default constructor in Circle class that sets radius, xCoordinate & yCoordinate to some default value e.g. -1;c. Write a Parameterized constructor in Circle class which takes xCoordinate, yCoordinate and radius as a parameter.Now write a ColoredCirlce class with private instance variable as color (String) and public setter & getters.

- *using java* Create a class AnimalCreate a class Cat, and a class Dog, and a class Bearded Dragon which extend Animal. Add to your Animal class: Member: name Methods: Public Animal(String name) //constructor public void makesSound()with the implementation printing out a generic animal sound. Next, override (add) the makesSound()method to your Cat and Dog class, with the implementation specific to each animal (i.e, cat says purr..). Do not override the makesSound() for your Dragon (bearded dragons don’t make sounds!)Note, you’ll also need a constructor in each of your subclasses which calls super(name) to initialize the common ‘name’ member of Animal. --- Next (in your test harness) create a List of different Animals ( a couple cats, a dog, a dragon... ) and add these Animals to your list. Iterate through your list & call makeSound on each. ( you should observe the implementation of the makeSound() method called will be: cat -> from Cat class, dog-> from Dog class,…Assume the Book class is defined as follows: public class Book{ enum Type type {FICTION,NON_FICTION}; public int isbn; public Type type; Book(int isbn, Type type){ this.isbn = isbn; this.type = type; }} Define filterBooksOfGivenType method that shall return ArrayList of Book of the type specified in parameter.Consider the following design for a Product class that keep track of product inventory: public class Product { public Product(String name, double qty){} public double getQty(){} public void reduce(double qty){} public void increase(double qty){} private String prodName; private double qtyOnHand; /* Data */ } Write the code for a main() method that models the following: A grocer starts the day with 50 Hard Rolls and 25 Soft Rolls. She sells 20 Hard Rolls and 10 Soft Rolls. The next morning about half of the Soft Rolls have turned into Hard Rolls. A shipment of 50 Soft Rolls comes in. She sells 30 Soft Rolls and 20 Hard Rolls. The storeowner wants a printout telling how many of each product she now has on hand.
