Examples of java.util.Set.containsAll()

java.util.Set.containsAll()
Returns true if this set contains all of the elements of the specified collection. If the specified collection is also a set, this method returns true if it is a subset of this set. @param c collection to be checked for containment in this set @return true if this set contains all of the elements of thespecified collection @throws ClassCastException if the types of one or more elementsin the specified collection are incompatible with this set (optional) @throws NullPointerException if the specified collection contains oneor more null elements and this set does not permit null elements (optional), or if the specified collection is null @see #contains(Object)
