asUnmodifiable in interface MutableCollection<T>Collections.unmodifiableCollection(Collection)MutableList<T> asSynchronized()
MutableCollectionCollections.synchronizedCollection(this) only with a return type that supports the full
iteration protocols available on MutableCollection.
The preferred way of iterating over a synchronized collection is to use the internal iteration
methods which are properly synchronized internally.
MutableCollection synchedCollection = collection.asSynchronized();
...
synchedCollection.forEach(each -> ... );
synchedCollection.select(each -> ... );
synchedCollection.collect(each -> ... );
If you want to iterate using an imperative style, you must protect external iterators using
a synchronized block. This includes explicit iterators as well as JDK 5 style for loops.

MutableCollectionExample using a Java 8 method reference:
Multimap<String, Person> peopleByLastName =
people.groupBy(Person::getLastName);
Example using an anonymous inner class:
Multimap<String, Person> peopleByLastName =
people.groupBy(new Function<Person, String>()
{
public String valueOf(Person person)
{
return person.getLastName();
}
});
Co-variant example for MutableCollection:
MutableMultimap<String, Person> peopleByLastName =
people.groupBy(Person::getLastName);
