Java 8 forEach method with example By Chaitanya Singh Filed Under java In Java 8 we have a newly introduced forEach method to iterate over collections and Streams in Java In this guide we will learn how to use forEach and forEachOrdered methods to loop a particular collection and stream Java 8 forEach to iterate a Map Java 8 forEach method with example BeginnersBook. In Java there are several ways to iterate over collections arrays or maps When Java first appeared iteration was achieved using Iterators In Java 5 the enhanced for loop or for each for String s collection was introduced to eliminate clutter associated with iterators Java 8 introduced a new concise and powerful way of iterating over collections the forEach method Stream Iteration using Java 8 forEach With both the new forEach method and the Java 8 Stream API you can create a stream of elements in a collection and then pipeline the stream to a forEach method for iteration The code to iterate through a stream of elements in a List is this public static void iterateThroughListStream List String list list stream forEach System out println
