a class that implements an interface must define all methods contained in that interface
I know that (K&B book) on the exam we wont be asked to make esoteric dinstictions between keywords and manifest consants: null,true & false.
i assumed the JVM identifies keywords by boldfacing them(if theres such a thing) and this is what happens with manifest constans as well.
why not just make them keywords, anyone with a clue?
The following character sequences, formed from ASCII letters, are reserved for use as keywords and cannot be used as identifiers (�3.8)... While true and false might appear to be keywords, they are technically Boolean literals (�3.10.3). Similarly, while null might appear to be a keyword, it
is technically the null literal (�3.10.7).
a literal is the source code representation of a value of a primitive type, the String type, or the null type.
