Question

PLEASE DO IN C# AND MAKE SURE I CAN COPY CODE IN VISUAL STUDIO Exercise #1: Design and implement class Rectangle to represent a rectangle object. The class defines the following attributes (variables) and methods: 1. Two Class variables of type double named height and width to represent the height and width of the rectangle. Set their default values to 1.0 in the default constructor. 2. A non-argument constructor method to create a default rectangle. 3. Another constructor method to create a rectangle with user-specified height and width. • Python only: use the classmethod decorator 4. Method getArea() that returns the area. 5. Method getPerimeter() that returns the perimeter. 6. Method getHeight() that returns the height. 7. Method getWidth() that returns the width. Now design and implement a test program to create two rectangle objects: one with default height and width, and the second is 5 units high and 6 units wide. Next, test the class methods on each object to print the information as shown below. Sample run: First object: Height: 1 unit Width: 1 unit Area: 1 unit Perimeter: 4 units Second object: Height: 5 unit Width: 6 unit Area: 30 units Perimeter: 22 units

Answer 1

package com;

public class Rectangle {

// Instance Variables

private int width;

private int height;

  

  

// Constructor which takes two variables width and height

public Rectangle(int height, int width)

{

// Setting the instance variables

this.width = width;

this.height = height;

}

// Default Constructor

public Rectangle() {

this.width = 1;

this.height = 1;

}

// Getter named getWidth which returns the width of the rectangle.

public int getWidth() {

return width;

}

// Getter named getHeight which returns the height of the rectangle.

public int getHeight() {

return height;

}

// This method returns perimeter of rectangle

private int getPerimeter() {

// TODO Auto-generated method stub

return 2*(this.width+this.height);

}

// This method returns area of rectangle

private int getArea() {

// TODO Auto-generated method stub

return this.width*this.height;

}

// Main method to test the toString method and it is optional

public static void main(String[] args)

{

Rectangle r1=new Rectangle(); // Creating default Rectangle object

Rectangle r2=new Rectangle(5, 6); // Creating parameterized Rectangle object

System.out.println("First object: ");

System.out.println(" Height: "+r1.getHeight()+"unit\n Width: "+r1.getWidth()+"unit\n Area: "+r1.getArea()+"units\n Perimeter: "+r1.getPerimeter()+"units");

System.out.println("Second object: ");

System.out.println(" Height: "+r2.getHeight()+"unit\n Width: "+r2.getWidth()+"unit\n Area: "+r2.getArea()+"units\n Perimeter: "+r2.getPerimeter()+"units");

}

  

}

output:
