Good day. Interested in a simple Java example of how to organize multi-threaded write / read from a collection. thank

    The easiest way is probably to take advantage of synchronized collections:

    List<C> list = Collections.synchronizedList(new ArrayList<C>());

    Record and reading are automatically synchronized, you can work freely from different streams. This, however, concerns only add / delete: indexing or iteration requires synchronization:

     list.add(new C()); synchronized (list) { Iterator i = list.iterator(); while (i.hasNext()) // работаем с i.next() }
