Question

Define a method void Area () in a class rectangle, which takes two float type arguments for length and breadth ; then, calculate and return the area of the rectangle.​

Answer 1

Answer:

class Rectangle {

   int length;  

   int breadth;  

   int area;  

   int perimeter;

   void input() {

       Scanner in = new Scanner(System.in);

       System.out.print("Enter length of rectangle: ");

       length = in.nextInt();

       System.out.print("Enter breadth of rectangle: ");

       breadth = in.nextInt();

   }

   void calculate() {

       area = length * breadth;

       perimeter = 2 * (length + breadth);

   }

   void display() {

       System.out.println("Area of Rectangle = " + area);

       System.out.println("Perimeter of Rectangle = " + perimeter);

   }

   public static void main(String args[]) {

       Rectangle obj = new Rectangle();

       obj.input();

       obj.calculate();

       obj.display();
