Java 8 forEach Example

Date: 2018-01-30

This article demonstrates using Java 8's forEach() method to iterate over collections (Lists, Sets, Maps). It explains that forEach() is an enhanced for loop, offering advantages over traditional loops, such as parallel processing via parallel streams and concise code using lambda expressions. The tutorial provides a step-by-step guide to creating a Java Maven project in Eclipse and implementing forEach() with examples. Importantly, forEach() is a terminal operation; the stream cannot be reused after calling it. The article also includes a comparison with the older enhanced for loop (introduced in Java 5).
