are not enlisted in the complete list of keywords of the K&B book, page 6. It should mean that i can use these as identifiers in my code. But complier detects error if i do so. Why aren't these words enlisted in the list then?

Null, false and true are not listed in reserved keywords cause they are actually literals. Hence cannot be used as an identifier.
And FYI, literals are constant value (
or number) used in Java programs.
