int area;

public void calcualteArea()

{

area = length*breadth;

}

public static void main(String args[])

{

Rectangle r = new Rectangle();

r.length = 10;

r.breadth = 20;

r.calcualteArea();

System.out.println("The Area of rectangle of length \""

+r.length+"\" and breadth \""+r.breadth+"\" is \""+r.area+"\"");

}
