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.

RichIterableflatCollect is a special case of RichIterable.collect(Function). With collect, when the Function returns
a collection, the result is a collection of collections. flatCollect outputs a single "flattened" collection
instead. This method is commonly called flatMap.
Consider the following example where we have a Person class, and each Person has a list of Address objects. Take the following Function:
Function<Person, List<Address>> addressFunction = Person::getAddresses; RichIterable<Person> people = ...;Using
collect returns a collection of collections of addresses.
RichIterable<List<Address>> addresses = people.collect(addressFunction);Using
flatCollect returns a single flattened list of addresses.
RichIterable<Address> addresses = people.flatCollect(addressFunction);
