Kommentarer

ArrayList null accepterar som ett giltigt värde och tillåter duplicerade element.

Ordningen på elementen ICollection i bevaras i ArrayList.

Om den nya Count (aktuell Count plus storleken på samlingen) blir större än Capacityökas kapaciteten ArrayList för den genom att automatiskt omlokalisera den interna matrisen så att den passar de nya elementen, och de befintliga elementen kopieras till den nya matrisen innan de nya elementen läggs till.

ArrayList Om kan hantera de nya elementen utan att öka , är den Capacityhär metoden en O(n) åtgärd, där n är antalet element som ska läggas till. Om kapaciteten behöver ökas för att rymma de nya elementen blir den här metoden en O(n + m) åtgärd, där n är antalet element som ska läggas till och m är Count.
