title: Concurrent Arrays in Java
body: <p>So, there is a <a href="http://download.oracle.com/javase/1,5.0/docs/api/java/util/concurrent/ConcurrentHashMap.html">concurrent hashmap</a> in Java, the advantage of which is not to lock down the whole hash table, but only portions of it. I was wondering whether there was such a construction for arrays. Particularly when an array is being resized locking down the whole array is not desirable, especially in real time applications. Anything out there?</p>
