class="vp-article-excerpt"><h2>The Change you need: Streams and Lambda</h2>
<p>After learning about streams and lambdas in Java 8, my style of writing code underwent a fundamental change. It reduced bugs in my code, got me thinking more in terms of functional programming, and best of all — it reduced the number of lines I had to write for any given functionality while making the code even more readable!</p>
