Writing variables is like in Java Bean like

1. private String password;
2. private String password = null;
3. private String password = "";

Which will be better programming approach and why?
Please elaborate.

Well, it all depends on what you want your variables to be initialised to! There is no 'best answer' in this case, although I suspect a lot of people by default (and IDEs) would produce private String password; (which is effectively the same as private String password = null;).
