  • TEST obj = null;  -- means that the object is set to nothing or null reference. when trying to accees ,the object initialized as TEST obj = null; will throw  a nullreferenceexception.

    TEST obj = new TEST(); -- indicates a valid initialization, obj helds reference to type test.i.e some memory has been allocated by the .net framework for it.
