Was genau soll das sein...?
ReplyDeleteDie klassische Art, ein Java-Programm zu dokumentieren. Idealerweise schreibt man ins JavaDoc natürlich hinein, was das Programm tut, statt das Offensichtliche zu wiederholen.
ReplyDeleteIdealerweise würde der Kommentar bei der Funktion also eher in folgende Richtung gehen: "Calculates the result of concatenating b copies of the given String a and dividing the length of the resulting String by 3.4. @param a The String that should be copied and used for the calculation described above. Must not be null. @param b How often the String will be copied and concatenated. May be zero or negative. @returns the result of the calculation described above. @throws NullPointerException if null was given as String argument a."
