Sorting a List in parallel without creating a temporary array in Java 8

Question

Java 8 provides java.util.Arrays.parallelSort, which sorts arrays in parallel using the fork-join framework. But there\'s no corresponding Collections.parallelSort

Answer 1

Use the following:

yourCollection.parallelStream().sorted().collect(Collectors.toList());

This will be parallel when sorting, because of parallelStream(). I believe this is what you mean by parallel sort?
