Class Stack<E>

  • All Implemented Interfaces:
    java.lang.Iterable<E>, java.util.Collection<E>, java.util.List<E>, java.util.RandomAccess

    class Stack<E>
    extends java.util.AbstractList<E>
    implements java.util.RandomAccess
    A non-synchronized stack with a non-modifiable list view which starts at the top of the stack. While LinkedList can provide the same behavior, it creates many temp objects upon frequent pushes/pops.
