Java 8 partition list

Question

Is it possible to partition a List in pure Jdk8 into equal chunks (sublists).

I know it is possible using Guava Lists class, but can we do it with pure Jdk? I don\'t wan

Answer 1

That can be done easily using the subList() method:

List collection = new ArrayList<>(21);
// fill collection
int chunkSize = 10;
List> lists = new ArrayList<>();
for (int i = 0; i < collection.size(); i += chunkSize) {
    int end = Math.min(collection.size(), i + chunkSize);
    lists.add(collection.subList(i, end));
}
