Easy way to convert Iterable to Collection

Question

In my application I use 3rd party library (Spring Data for MongoDB to be exact).

Methods of this library return Iterable, while the rest of my

Answer 1

You can use Eclipse Collections factories:

Iterable iterable = Arrays.asList("1", "2", "3");

MutableList list = Lists.mutable.withAll(iterable);
MutableSet set = Sets.mutable.withAll(iterable);
MutableSortedSet sortedSet = SortedSets.mutable.withAll(iterable);
MutableBag bag = Bags.mutable.withAll(iterable);
MutableSortedBag sortedBag = SortedBags.mutable.withAll(iterable);

You can also convert the Iterable to a LazyIterable and use the converter methods or any of the other available APIs available.

Iterable iterable = Arrays.asList("1", "2", "3");
LazyIterable lazy = LazyIterate.adapt(iterable);

MutableList list = lazy.toList();
MutableSet set = lazy.toSet();
MutableSortedSet sortedSet = lazy.toSortedSet();
MutableBag bag = lazy.toBag();
MutableSortedBag sortedBag = lazy.toSortedBag();

All of the above Mutable types extend java.util.Collection.
