All Implemented Interfaces:
IndexedList<E>, Iterable<E>, List<E>, Traversable<E>, Iterable<E>
public class ArrayList<E> extends AbstractIndexedList<E>
ArrayList is an IndexedList implementation backed by an array.

WARNING: All modifications copy the entire backing array. ArrayLists should only be used where modifications are infrequent and access times are critical. ArrayList is also compact in memory usage, so may be appropriate for small lists. If there is any doubt regarding access patterns for a List then use a Vector instead.

      toInclusive - if true, the element at the to index will be included

    • get

      public E get(int i)
      Description copied from interface: List
      Returns the element at the specified index in this list (zero-based).

    • first

      @Nullable public E first()

      Overrides:
      size in class AbstractTraversable<E>

    • isEmpty
