Java 8 Parallel Streams Example

Date: 2018-01-22

This tutorial explains Java 8's parallel streams, a feature leveraging multi-core architectures for improved performance. Parallel streams process operations concurrently, significantly speeding up tasks like filtering large datasets. Creating a parallel stream is simple—use parallelStream() instead of stream() on a collection. However, only stateless, non-interfering, and associative operations are suitable for parallel processing. The article provides a practical example of counting employees with salaries above a threshold, showcasing the performance difference between sequential and parallel streams. The tutorial includes a step-by-step guide to creating a Java Maven project in Eclipse to demonstrate the code.
