The java.lang.StringBuilder.append() metoda se uporablja za dodajanje nizovne predstavitve nekega argumenta zaporedju. Obstaja 13 načinov/oblik, v katerih je mogoče uporabiti metodo append() s posredovanjem različnih vrst argumentov:

StringBuilder append( logično a ) : java.lang.StringBuilder.append( logično a ) je vgrajena metoda v Javi, ki se uporablja za dodajanje nizovne predstavitve logičnega argumenta danemu zaporedju.





Sintaksa:

public StringBuilder append( boolean a )>

Parameter: Ta metoda sprejme en sam parameter a logičnega tipa in se nanaša na logično vrednost, ki jo je treba dodati.

Povratna vrednost: Metoda vrne sklic na ta objekt.






Primeri:

 Input: string_buffer = 'We are Indians' boolean a = true Output: We are Indians true>
