Using an underscore in a java variable is not a good practice, unless it is a constant. See this question for more details.
Also generally names starting with _ are sometimes used as system variables and there is no sense in starting your variable with _ .

Edit: Question about constant naming conventions.

Do you have a link to some documentation that says that constants can be named with an underscore? That would be a good thing to add to your answer. – Arc676 Jan 25 '16 at 10:01
