Examples of java.util.Set.addAll()

java.util.Set.addAll()
Adds all of the elements in the specified collection to this set if they're not already present (optional operation). If the specified collection is also a set, the addAll operation effectively modifies this set so that its value is the union of the two sets. The behavior of this operation is undefined if the specified collection is modified while the operation is in progress. @param c collection containing elements to be added to this set @return true if this set changed as a result of the call @throws UnsupportedOperationException if the addAll operationis not supported by this set @throws ClassCastException if the class of an element of thespecified collection prevents it from being added to this set @throws NullPointerException if the specified collection contains oneor more null elements and this set does not permit null elements, or if the specified collection is null @throws IllegalArgumentException if some property of an element of thespecified collection prevents it from being added to this set @see #add(Object)
