UML Help

+ = Public
- = Private
# = ?
~ = ?

I know one of those is a constant however, I’m just not sure which one.
*edit* My question

1 - What does # and ~ stand for.

thanks

# indicates a protected value.

UML visibility attributes:

+ (public)
- (private)
~ (package)
# (protected)

# protected is the same thing as final? Is a constant a protected value?

Also if i was writing a UML chart for someone and i left something like this,

+ MY_DOB: int = 2183

Wouldnt that be assumed to be a constant since it is in all caps?

Thanks

This is a good page about UML representation of constants (among other things): http://ei.cs.vt.edu/~kafura/java/Cha...constants.html
