virtual function will not compile, and this helps catch common errors. The specifiers serve as documentation; if no specifier is present, the reader has to check all ancestors of the class in question to numbers that are never negative. This is intended as a form 37 of self-documentation. However, in C, the advantages of such documentation are outweighed by the real bugs it can introduce. Consider: for (unsigned that we use already, allows shorthands for some operations, and has some performance and safety improvements. 49 The C++11 standard is substantially more complex than its predecessor (1,300 pages versus

We do not use the phrase “documentation comments”, instead using the common term “Javadoc.” Other “terminology notes” will appear occasionally public String toString() { return "yes"; } }, NO, MAYBE } An enum class with no methods and no documentation on its constants may optionally be formatted as if it were an array initializer (see Section 4 Annotations Annotations applying to a class, method or constructor appear immediately after the documentation block, and each annotation is listed on a line of its own (that is, one annotation per line).
