Question

(The rectangle class) Following the example of the circle class in 8.2, a class named rectangle to represent a rectangle. The class contains: Two double data fields names width and height that specify the width and height of the rectangle. The default values are 1 for both width and height, A constructor that creates a default rectangle. A constructor that creates a rectangle with the specified width and height, A method names get Area O that returns the area of this rectangle. A method named get Perimeter O that returns the perimeter. Draw the UML diagram for the class. Implement the class. Wright a test program that two Rectangle objects- one with width 4 and height 40 and the with width 3.5 and height 35.9. Display the width, height, area, and of each rectangle in this order.

Explanation / Answer

please rate - thanks

message me if any problems

import java.util.Scanner;
public class rectangletest
{
public static void main (String[] args)
{Scanner in=new Scanner(System.in);
double h,w;
System.out.println("for rectangle 1: ");
System.out.print("Enter height: ");
h=in.nextDouble();
System.out.print("Enter width: ");
w=in.nextDouble();
Rectangle r1= new Rectangle(w,h);
System.out.println("for rectangle 2: ");
System.out.print("Enter height: ");
h=in.nextDouble();
System.out.print("Enter width: ");
w=in.nextDouble();
Rectangle r2= new Rectangle(w,h);
System.out.println();
System.out.println("rectangle 1:");
System.out.println("width: "+r1.getWidth());
System.out.println("height: "+r1.getHeight());
System.out.println("area: "+r1.getArea());
System.out.println("perimeter: "+r1.getPerimeter());
System.out.println();
System.out.println("rectangle 2:");
System.out.println("width: "+r2.getWidth());
System.out.println("height: "+r2.getHeight());
System.out.println("area: "+r2.getArea());
System.out.println("perimeter: "+r2.getPerimeter());

}
}


--------------------------------------------

public class Rectangle
   {
    private double width;
    private double height;
    public Rectangle()
        {width=1;
         height=1;
        }

    public Rectangle(double w,double h )
        {width=w;
         height=h;
        }

   public double getPerimeter()
       {return 2*height+ 2*width;
       }

    public double getArea()
        {return height*width;
        }
public double getHeight()
       {return height;
       }
public double getWidth()
       {return width;
       }
