I read in "Java 2 The complete Reference" that java reserves true, false and null
If I am right these are the values defined by java and these words may not be used for variable,class or method names.so can we consider them as keywords?
thanks

Well, they're actually reserved literals. A literal is a constant, like 'x', 42 or 3.14159

They are not keywords, they are literals. Things like "if" and "for" are keywords. "true" and "null" are literals just like 1 and 7.5 are.

They act like keywords. But for the exam, you must not consider them as keywords. If a question
ask you whether they are keywords, answer NO.

I don't believe you'll have to make the distinction between keywords and literals on this exam. As far as I know, this is beyond the scope of the exam.
