## Interface BoundedCollection<E>

- Type Parameters:
    `E` - the type of elements in this collection
  All Superinterfaces:
    Collection<E>, Iterable<E>
  All Known Implementing Classes:
    CircularFifoQueue, FixedSizeList, UnmodifiableBoundedCollection

      public interface BoundedCollection<E>
      extends Collection<E>

  Defines a collection that is bounded in size.

  The size of the collection can vary, but it can never exceed a preset maximum number of elements. This interface allows the querying of details associated with the maximum number of elements.
