{
    int a;
  
    Test cloning()
    {
        try
        {
            return (Test) super.clone();
        }
        catch(CloneNotSupportedException e)
        {
            System.out.println("CloneNotSupportedException is caught");
            return this;
        }
    }
}
  
class demo
{
  
    public static void main(String args[])
    {
        Test obj1 = new Test();
        Test obj2;
        obj1.a = 10;
        obj2 = obj1.cloning();
        obj2.a = 20;
  
        System.out.println("obj1.a = " + obj1.a);
        System.out.println("obj2.a = " + obj2.a);
    }
}


(A)

obj1.a = 10
obj2.a = 20

(B)

obj1.a = 20
obj2.a = 20

(C)
