I faced a rather simple question in an interview.
Why do we use the class keyword for declaring classes?
Short answer: because that’s the way it’s done in C++. Java has taken the bulk of its syntax from C++ – a wise decision, in my opinion, as it really helped with drawing programmers when it was still new.
Now, if your question is why a keyword is needed at all – i.e. why can’t the compiler just deduce where classes are declared – maybe it can, but using a keyword has the benefits of
EDIT: one other things – some things simply cannot be deduced by the compiler in the Java syntax – for example, the only difference between an empty class and an empty interface (both legal in Java) is the
class/interfacekeyword.
