Parallel Streams for Large Data Processing in Java

Parallel streams can significantly improve the performance of operations on large datasets by leveraging multiple cores of modern CPUs. However, use them judiciously as they may not always lead to performance gains, depending on the data size and the complexity of operations performed.

Source Code

List strings = Arrays.asList("one", "two", "three", "four", "five");
List result = strings.parallelStream().filter(s -> s.length() > 3).collect(Collectors.toList());
System.out.println(result);
