Słowniczek
abstract
Słowo kluczowe abstract służy do deklarowania metod i klas abstrakcyjnych. Metoda abstrakcyjna nie ma zdefiniowanej implementacji. Jest jak zwykle zadeklarowana z argumentami i typem zwracanym, ale ciało ujęte w nawiasy klamrowe jest zastąpione średnikiem. Implementację metody abstrakcyjnej zapewnia podklasa klasy, w której jest zdefiniowana. Jeśli w jakiejś klasie pojawia się metoda abstrakcyjna, taka klasa również jest abstrakcyjna. Próba utworzenia instancji klasy abstrakcyjnej zakończy się niepowodzeniem w trakcie kompilacji.
