Sorry,
but bill is right....

Look at the JLS, chapter 3.9....
Keywords: one of.... const .... goto...
Every keyword is a reserved word, including const and goto (this has nothing to do if they are used or not, they are keywords).
Reserved word are mostly keywords, BUT there are some, which are NOT keywords BUT reserved...
These are the boolean literals true and false and the null literal...
hope that helps
