Is there in one of the specifications any reference to methods that start with "is", while the suffix of the method's name is a property's name (similar to getter/setter methods)?

I was trying to find out an explanation about it but search engines omit the word "is".

Thanks!

Yes, there is. It's the JavaBeans Specification and you'll find it here. At least not quite there, but if you accept the licence agreement on that page you can download the spec. The part about "public boolean isProperty()" is section 8.3.2.

If you look in the API index under "I", you will find lots of methods beginning "is". The equivalent of "get" when you want to return a boolean is "is" (or "has"). So you will find methods like "isEnabled" "isLetter" or "hasNext".
