Question

Using C#, Create class Rectangle. * The class has attributes length and width, each of which defaults to 1. * One instance constructor that initializes the attributes length and width when an instance is created * It has several methods as described below: methodA - this is a static method that can only be accessed inside of the class Rectangle. It calculates the Area of the rectangle. methodB - this is a static method that can be accessed from another class. It calculates the Area of the rectangle. methodC - this is an instance method that can only be accessed inside of the class Rectangle. It calculates the Area of the rectangle. methodD - this is an instance method that can be accessed from another class. It calculates the Area of the rectangle. * in the Main method, each method above is called * Write class testRectangle to call the methods in class Rectangle that can be accessed by class testRectangle.

Explanation / Answer

//Below is the c # code

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

namespace ProjectRectangle
{
    class Rectangle
    {
        static double length = 1;
        static double width = 1;

        Rectangle(double len, double wid)
        {
            length = len;
            width = wid;
        }

        //this is a static method that can only be accessed inside of the class Rectangle.
        //It calculates the Area of the rectangle
        private static double methodA()
        {
            return length * width;
        }

        //this is a static method that can be accessed from another class.
        //It calculates the Area of the rectangle.
        public static double methodB()
        {
            return length * width;
        }
        //this is an instance method that can only be accessed inside of the class Rectangle.
        //It calculates the Area of the rectangle
        private double methodC()
        {
            return length * width;
        }
        //this is an instance method that can be accessed from another class.
        //It calculates the Area of the rectangle. *
        public double methodD()
        {
            return length * width;
        }
        static void Main(string[] args)
        {

            Rectangle rect = new Rectangle(11, 15);
            Console.WriteLine("Calculate Area of the rectangle from static method is " + methodA());
            Console.WriteLine("Calculate Area of the rectangle using instance method is " + rect.methodC());
            Console.ReadLine();
        }
     
    }

}

OUTPUT:

Calculate Area of the rectangle from static method is 165
Calculate Area of the rectangle using instance method is 165
