Keywords again

[N Mukherjee]

Hi,
As per the RHE book,true,false,null are keywords
But to my belief, these are literals only!
Well, strictfp is a keyword but what about switch?
Well, I feel it's a keyword too
But why then the book(See page 6 and 7) didnot mention it!
Please put some light on this and correct me if i am wrong!
regards and thanks javaranch for your kind contribution to java
society in general

nm,
switch is definitely a keyword and it is very much mentioned on the last line of page 6 unless you have a older version and it is not mentioned there. In the latter case I suggest you check the errata. Also, for the latest list of keywords, please refer to the link below.

The widefp keyword implemented in Beta 4 has been removed due to public review feedback. true, false are boolean literals and
null is just ;-) a reserved word. Java identifires must not be true, false or null.

One thing I recall from my studies is that no Java exam will ask you to distinguish between "keywords" and "reserved words".
