Convert to a thread-safe collection

There are eight static methods in the class Collections that convert a regular collection to a thread-safe one:

• Set<T> synchronizedSet(Set<T> set)
• List<T> synchronizedList(List<T> list)
• Map<K,V> synchronizedMap(Map<K,V> map)
• Collection<T> synchronizedCollection(Collection<T> collection)
• SortedSet<T> synchronizedSortedSet(SortedSet<T> set)
• SortedMap<K,V> synchronizedSortedMap(SortedMap<K,V> map)
• NavigableSet<T> synchronizedNavigableSet(NavigableSet<T> set)
• NavigableMap<K,V> synchronizedNavigableMap(NavigableMap<K,V> map)

A thread-safe collection is constructed so that two application threads can only modify it sequentially without stepping on each other's temporary results. But, multithreaded processing ...
