Здравствуйте, TARGRED, Вы писали:

TAR>А что обозначает слова final, пока папаграф читал, уже 3 раза встретил

final class member, or variable — the value of these variables can not be changed anymore once they have been initialized
final method — this method can not be overriden in the subclasses
final class — this class can not be subclassed


P.S.
if you do not understand english let me know, I will translate in russian for you.
