The uničiti () metoda razreda niti se uporablja za uničenje skupine niti in vseh njenih podskupin. Skupina niti mora biti prazna, kar pomeni, da so se vse niti, ki so bile v skupini niti, od takrat ustavile.
Sintaksa
public void destroy()
Vrnitev
Ne vrne nobene vrednosti.
Izjema
IllegalThreadStateException: Ta izjema se sproži, če skupina niti ni prazna ali če je bila skupina niti že uničena.
SecurityException: Če trenutna nit ne more spremeniti te skupine niti.
