       Circle circle1= new Circle(1);
       Circle circle2= new Circle(2);

       ///swappingggg
       System.out.println("b4 swap: circle 1 is " + circle1.radius +
"circle2="+circle2.radius);
       swap(circle1,circle2);
       System.out.println("after swap: circle 1 is " + circle1.radius +
"circle2="+circle2.radius);
   }
   public static void swap(Circle x, Circle y){
       System.out.println("b4 swap: x=" + x.radius + "y ="+ y.radius);

       Circle temp = x;
       x = y;
       y = temp;

       System.out.println("After swap: x=" + x.radius + " y = " +
y.radius);
   }
}
