Java 8 Stream support sequential as well as parallel processing, parallel processing can be very helpful in achieving high performance for large collections. That is why we can say it is Possibly unbounded. While collections have a finite size, streams need not. Short-circuiting operations such a...
In this article we will be discussing about java 8 parallel streams. We will look into different examples of using parallel stream, differences between sequential and parallel streams and performance improvement with parallel streams in java 8.
In this Java 8 tutorial, I have shared some simple examples of java.util.Stream package, which you can use in your day-to-day Java programming tasks.Streams are one of the most important additions on JDK, it allows you to leverage other changes like lambda expression, method reference, ...
