Understanding the Basics of Java Streams

Hey everyone! 🤗 Let's dive into the essentials of Java Streams—a powerful addition to the Java 8 toolkit.

What are Java Streams?
They represent a sequence of elements supporting sequential and parallel aggregate operations. This means you can process collections of data efficiently!

Key Features:
- Declarative: Write code in a more concise and readable way.
- Lazy Evaluation: Operations are performed only when needed.
- Parallel Processing: Easily utilize multi-core architectures.

Example of Filtering a List:

List<String> names = Arrays.asList("Alice", "Bob", "Charlie", "Diana");
List<String> filteredNames = names.stream()
                                  .filter(name -> name.startsWith("A"))
                                  .collect(Collectors.toList());

In this example, we filter names that start with "A".

Why use Java Streams?
- Less boilerplate: Cleaner code.
- Increased productivity: Focus on the "what" rather than the "how".

Give it a try and explore the wonders of data processing with Java Streams! 🌟
