coding style - Is there a standard in java for _ (underscore) in front of variable or class names?

Question

I have seen some programmers using _ (underscore) in front of class names, and others using it for local variables.

Does the Java standard require/suggest the use of _ (underscore) in front of an private instance variable or class name?

Answer 1

I think artifacts like these are pre-IDE and C++ vintage. Don't do it.
