설명

ArrayList 는 null 유효한 값으로 허용되고 중복 요소를 허용합니다.

새 Count 요소(컬렉션의 현재 Count 및 크기)가 보다 Capacity크면 새 요소를 수용하도록 내부 배열을 자동으로 다시 할당하여 용량 ArrayList 이 증가하고 새 요소가 추가되기 전에 기존 요소가 새 배열에 복사됩니다.

같Count으면 index 요소가 의 ArrayList끝에 추가됩니다.

에 있는 ICollection 요소의 순서는 에 유지됩니다 ArrayList.

목록과 같은 연속 요소의 컬렉션에서 삽입 지점을 따르는 요소는 새 요소를 수용하기 위해 아래로 이동합니다. 컬렉션이 인덱싱되면 이동되는 요소의 인덱스도 업데이트됩니다. 이 동작은 해시 테이블과 같이 요소가 개념적으로 버킷으로 그룹화되는 컬렉션에는 적용되지 않습니다.

이 메서드는 O(n + m) 추가할 요소의 수가 있는 n 연산입니다 mCount.
