The article ( http://developer.java.sun.com/developer/onlineTraining/collections/Col lection.html#VectorAndStackClasses) gives an example of using a synchronized ArrayList: lst = Collections.synchronizedList(lst); synchronized (lst) { Iterator iter = lst.iterator(); while (iter.hasNext()) System.out.println(iter.next()); } My question is: If I'm using Vector do I need an explicit synchronized call while iterating too? If not, then isn't Vector easier to use if you need just a thread-safe List? Another question regarding the ArrayList: Should I do something like this - public void    More>>

			

			lst = Collections.synchronizedList(lst);
			

			synchronized (lst) {
			

			Iterator iter = lst.iterator();
			

			while (iter.hasNext())
			

			System.out.println(iter.next());
			

			}
			

		

			

			public void foo()
			

			{
			

			//lst is previously allocated
			

			//synchronized ArrayList
			

			synchronized(lst)
			

			{ .....
			

			int size = lst.size();
			

			.....
			

			}
