Question

find the area and perimeter of cirlcle,rectangle,square using buffer reader class with inheritance in java​

Answer 1

class FindRectangleArea

{

   public static void main(String arg[])

   {

       Rectangle rect = new Rectangle(10, 5);

       

       System.out.println("Length = " + rect.length);

       System.out.println("Breadth = " + rect.breadth);

       System.out.println("Area = " + rect.getArea());

       System.out.println("Perimeter = " + rect.getPerimeter());

   

   }

}

class Rectangle

{

   double length;

   double breadth;

   Rectangle(double length, double breadth)

   {

       this.length = length;

       this.breadth = breadth;

   }

   double getArea()

   {

       return length * breadth;

   }

   double getPerimeter()

   {

       return 2 * (length + breadth);

   }
