When to prefer LinkedBlockingQueue over ArrayBlockingQueue?

Question

When to prefer LinkedBlockingQueue over ArrayBlockingQueue?

Which data structure to use among LinkedBlockingQueue and ArrayB

Answer 1

From the JavaDoc for ArrayBlockingQueue

A bounded blocking queue backed by an array.

_{Emphasis mine}

From the JavaDoc for LinkedBlockingQueue:

An optionally-bounded blocking queue based on linked nodes.

_{Emphasis mine}

So if you need a bounded queue you can use either, if you need an unbounded queue you must use LinkedBlockingQueue.

For a bounded queue, then you would need to benchmark to work out which is better.
