Does a final static nullObject is preferable to null pointer ? why ?

Thanks for your light :)

I would never recommend making a nullObject as a datamember. Relying on a object to be null or not is also dangerous.

I recommend the following:

1. construct a version of the object that will throw a specific exception if its not initialized.

2. if you must, use x==null
