In Java, you can sort arrays in parallel using the parallelSort method provided by the Arrays class. This feature was introduced in Java 8 and is part of the Java util package.
Parallel array sorting is particularly useful when you need to sort large arrays or lists in parallel to take advantage of multi-core processors and improve sorting performance.

Here’s how you can use parallelSort to sort arrays in Java:
import java.util.Arrays;
public class ParallelArraySorting {
public static void main(String[] args) {
int[] numbers = {5, 2, 9, 1, 5, 6, 8};
// Parallel sort the array
Arrays.parallelSort(numbers);
// Display the sorted array
for (int number : numbers) {
System.out.print(number + " ");
}
}
}
import java.util.ArrayList;
import java.util.Arrays;
import java.util.List;
public class ParallelListSorting {
public static void main(String[] args) {
List<Integer> numbersList =
new ArrayList<>(Arrays.asList
(5, 2, 9, 1, 5, 6, 8));
// Convert the list to an array and parallel sort
Integer[] numbersArray =
numbersList.toArray(new Integer[0]);
Arrays.parallelSort(numbersArray);
// Display the sorted array
for (int number : numbersArray) {
System.out.print(number + " ");
}
}
}
Parallel array sorting can provide significant performance benefits when sorting large arrays or lists. However, keep in mind that parallel sorting may not always be faster for smaller data sets due to the overhead of parallelism. The decision to use parallel sorting should be based on your specific use case and performance requirements.
Additionally, it’s worth noting that parallel sorting methods use the default comparator for sorting. If you need custom sorting criteria, you can provide your own comparator by using overloaded versions of parallelSort.
