Is LinkedList thread-safe when I'm accessing it with offer and poll exclusively?

Question

I have a linked list samples:

protected LinkedList samples = new LinkedList();

I\'m append

Answer 1

That is correct - LinkedList is not synchronized and thus not thread safe. If you do not want to use the newer synchronized analogies of LinkedList, namely, ConcurrentLinkedQueue or LinkedBlockingQueue, you can initialize LinkedList like this:

LinkedList samples = (LinkedList)Collections.synchronizedList(new LinkedList());
