PMJ,
I'm not Maha.
Hope you/Maha won't mind!!
Actually, there are 48 keywords in java, which are reserved, which you can't use as identifiers. Moreover,
true,
false and
null are not keywords but reserved words, which also cannot be used as identifiers.
For a list of keywords and reserved words, refer to
http://java.sun.com/docs/books/tutorial/java/nutsandbolts/_keywords.html .
goto and
const are keywords. Their significance is that - though they are keywords, they are as such not used in Java 2.
Actually, the difference between keywords and reserved words is a matter of much confusion!!
Regards,
Suresh.
