Mikalai Zaikin notes error

On this page http://java.boot.by/scjp-tiger/ch01s04.html, the author wrote: For boolean instance variables you may provide a getter method named is... or has... that returns a boolean, that can be used conveniently in boolean expressions
JavaBeans standard doesn't supports "has" at all!
PS: Correct me if Im wrong.

EDIT by mw: Corrected html link.

Yes you are right.
If the property is a boolean, the getter method's prefix is either get or is.

I'm not sure that Mikalai is taking JavaBeans into consideration here.
He's just saying that you may provide methods named such as is... or has... for convenience. Nothing stops you from doing it. For example, look at Iterator.hasNext() : a convenient way to return a boolean.

Please check the website again. Look at the top..where the heading is written..
"Develop code that declares both static and non-static methods, and - if appropriate - use method names that adhere to the JavaBeans naming standards."
Did you notice JavaBeans?
