In Java, Write a line of code that performs each of the following tasks : (a) Call superclass Employee's toString method from subclass Pieceworker's toString method. (b)Specify that class Pieceworker inherits from class Employee. (c) Call superclass Employee's constructor from subclass Pieceworker's constructor - assume that the superclass constructor receives three strings representing the first name, last name and social security number.
Create a class Reverse with one data member called num of type int and a static method find to return reverse of num. Create a subclass ReverseR from Reverse which overrides member of its super class. Write a main() method that tests in same class ReverseR. method find()) and this override method uses recursion to find and returns reverse of data
Can we override static methods of a class?
Java- Suppose that Vehicle is a class and Car is a new class that extends Vehicle. Write a description of which kind of assignments are permitted between Car and Vehicle variables.
Create a base class with an abstract print( ) method that is overridden in a derived class. The overridden version of the method prints the value of an int variable defined in the derived class. At the point of definition of this variable, give it a nonzero value. In the base-class constructor, call this method. In main( ), create an object of the derived type, and then call its print( ) method. Explain the results. (JAVA)
Answer the given question with a proper explanation and step-by-step solution. C++ Virtual Methods Create the following 3 classes: 1. AppWindow class, containing: - A protected instance of a rectangle class Rect defining the AppWindow's position (x,y) and size (w,h). (You may use the Rect class you developed in the previous lab. In main(), the width and height are assumed to be public and called "w" and "h".) - The following constructors to initialize the dimensions: AppWindow(); // initialize member rect's dimensions to 0AppWindow( float x, float y, float w, float h ); // initialize member rect's dimensions with the 4 floatsAppWindow( const Rect& r ); // initialize member rect's dimensions with r's dimensions - A method to retrieve the member rectangle: const Rect& get_rect(); - A virtual method called resize(). When this method is called, your implementation is supposed to change the dimensions of the internal rectangle of the window. virtual void resize( int w, int h ); 2.…
Write a Number class that holds a double, and add overloaded operators for +, –, *, /, and assignment. Choose the return values for these functions so that expressions can be chained together, and for efficiency. Write an automatic type conversion operator int( ). Please submit code in
Reuse your Car class . In a main, build an object of that class, and print out the object using System.out.println(). Notice that this simply reports the memory address of the object in question, and we’d like to do something more useful. To replace (or override) the toString (or equals) function. Now, build a toString function that prints out the make, model, and odometer reading for a vehicle object. public class Car { //instance variables private int odometer; private String make; private String model; //overloading //constructors public Car(int odometer,String make, String model) { this.odometer = odometer; this.make = make; this.model = model; } public Car(String make, String model) { this.make = make; this.model = model; } public Car(String make) { this.make = make; } /* *getter & setter methods */ public int getOdometer() { return odometer; } public void…
Write a java program in which Animal:Create a class Animal and Add a protected data member named id of integer type.• Add get/set methods for id data member in Animal class with public access. Also provide default constructor this should initialize id to 0.• Also provide parameterized constructor and toString method.• Add an abstract method tellAboutSelf method to Animal class with public access• Add another abstract method speak method to Animal class.Reptile, Bird, MammalNext create the three child classes which extends form Animal class.• Add a default constructor to each of the above created class. The constructor should initialize the id data member id, Reptile, Bird and Mammal, to 1, 2 and 3 respectively also it display a message “(class Name)’s default constructor”. E.g. for Bird it says “Bird’s default constructor”.• Add a parameterized constructor to each of the above created class. The constructor should initialize the id data member, Reptile, Bird and Mammal, to the…
what is the difference between overriding a super class method and overloading a super class method?
Method overload and method override are distinct concepts.
Consider the following class implementation, which represents a price in dollars and cents: class Price { private: int dollars; int cents; public: Price() { dollars = cents = 0; } Price(int d, int c) { dollars = d; cents = c; } bool operator!=(Price); bool operator<(Price); }; Write an implementation for both overloaded operators. != should return true if the Prices are not equivalent, and should return false if they are equivalent. < should return true if the Price of the calling object (left object) is less than the parameter Price object (right object). You do not need to demonstrate calling these operators.
