The first sentence of each documentation comment should be a summary sentence, containing a concise but complete description of the declared entity. This sentence ends at the first period that is followed by a blank, tab, or line terminator, or at the first tagline (as defined below). This simple rule means that a first sentence such as:
This is a simulation of Prof. Knuth's MIX computer.
will not work properly, because the period after the abbreviation "Prof" ends the
first sentence, as far as the Java documentation comment processor is concerned.
Take care to avoid such difficulties.
Sentences following the summary sentence but preceding the first tagged paragraph (if any) form the general description part of the documentation comment.
