I am looking for a similar library as ArrayBlockingQueue. Just that, I don’t need the thread safe feature (For better performance purpose) offered in it, as it is using ReentrantLock in the offer(E e) method.

What I would like is

  1. A FIFO queue.
  2. Has an initial capacity, where pushing new element in will fail if the queue is full.
  3. Thread safety is not a requirement.

I don’t find ArrayQueue in Java standard library. Or, am I missing any classes?

    There is a BoundedFiFoBuffer in the Common.Collections with the following properties:

    • The BoundedFifoBuffer is a very efficient implementation of Buffer that is of a fixed size.

    • The removal order of a BoundedFifoBuffer is based on the insertion order; elements are removed in the same order in which they were added.

    • The iteration order is the same as the removal order.

    • Note that this implementation is not synchronized.

    • BufferOverflowException is thrown on attempt to add elements to the full buffer.
