Interface List

  • All Superinterfaces:
    Collection
    All Known Implementing Classes:
    ArrayList, LinkedList
    public interface List
extends Collection
    The LEAP (environment-dependent) version of the &qote;java.util.List&qote; interface. This interface appears to be exactly the same in J2SE, PJAVA and MIDP. The internal implementation is different in the three cases however.

        the element at the specified position in this list.
        Throws:
        IndexOutOfBoundsException - if the index is out of range (index < 0 || index >= size()).

      • indexOf

        int indexOf​(Object o)
        Returns the index in this list of the first occurrence of the specified element, or -1 if this list does not contain this element.
