 int length;  int breadth;

Rectangle(int len,int bre)
  {  
length  = len;  breadth = bre; 
 }
public static void main(String args[]) 

{
  
      Rectangle r1 = new Rectangle(20,10);

  System.out.println("Length of Rectangle : " + r1.length);

  System.out.println("Breadth of Rectangle : " + r1.breadth);
  }
