Learn Java 8 streams by example: functional programming with filter, map, flatMap, reduce, collect, lambdas, sequential and parallel streams are covered in-depth in this tutorial.
This article explores some of Java 8’s new features, using both Java’s proposed syntax and Scala. We cover lambda expressions, higher-order functions, parallel collections and virtual extension methods aka traits. Besides this, we will provide insights into the new paradigms integrated in Java 8, such as functional programming.
