ConcurrentLinkedQueue is not a List but it is thread safe while accessing to its elements.

Consider using CopyOnWriteArrayList or other concurrent collections from java.util.concurrent. Also, Vector is in essence synchronized ArrayList, but this also means that it's basically the same as ArrayList wrapped with Collection.synchronizedList().

If you want us to help you with choosing appropriate collection, please specify details of your task.

i hope there are 2 ways ,

  1. extends arraylist to your own class and override each method make it thread safe to enable synchronization

  2. user CopyOnWriteArrayList which is another thread safe version of arraylist.

The method Collection.synchronizedList() just wraps an existing List by synchronizing all methods that can be accessed from a client class on a single mutex.

Nothing more nor less, if you want to emulate the behavior, the simplest way is to do exactly the same. But I don't see the point in doing it.
