E - the type of the elements in the collectionpublic class SynchronizedCollection<E> extends Object implements Collection<E>, Serializable
Collection to synchronize its behaviour
for a multi-threaded environment.
Iterators must be manually synchronized:

// do stuff with iterator
}
This class is Serializable from Commons Collections 3.1.
