Java Streams, introduced in Java 8, have revolutionized the way developers process and manipulate data. They enable a more functional programming approach, allowing you to write code that is both concise and readable while efficiently handling collections. Whether you’re filtering, mapping, or reducing data, Java Streams provide an elegant solution to simplify complex data operations.

In this blog, we’ll introduce you to the fundamentals of Java Streams, how they work, and why they are a game-changer in the Java ecosystem.

What Are Java Streams?

A Stream in Java represents a sequence of elements that can be processed in a declarative, functional style. Unlike collections, streams are not about storing data but about describing operations on the data. Streams allow you to express what you want to do with the data (filter, map, reduce), rather than focusing on how to do it (loops, conditions).

Key characteristics of Java Streams:

• Immutable: Streams do not modify the underlying data source. They create a new stream for each operation.
• Lazy Evaluation…
