Answer 1

if you have a JDK, you can look at the source code of "Collections.synchronizedList()". It is simple, so you can create a copy of this method specialized to get both LinkedList and synchronization functionnalities.

public class SynchronizedLinkedList implements List {

    private LinkedList list;

    private Object lock;

    public void add(T object) {
        synchronized(lock) {
            list.add(object);
        }
    }

    // etc.
}
