Class FIFOList<E>

  • Type Parameters:
    E - the class of the elements of this list.
    All Implemented Interfaces:
    java.io.Serializable, java.lang.Cloneable, java.lang.Iterable<E>, java.util.Collection<E>, java.util.List<E>, java.util.Queue<E>, java.util.RandomAccess
    public final class FIFOList<E>
extends java.util.Vector<E>
implements java.util.Queue<E>
    The FIFOList class represents a first-in-first-out (FIFO) stack of objects. The usual push and pop operations are provided, as well as a method to peek at the top item on the stack, a method to test for whether the stack is empty, and a method to search the stack for an item and discover how far it is from the top.

    When a stack is first created, it contains no items.
