Java 8 Innovations

This repository contains example Java classes demonstrating some of the most notable features introduced in Java 8.

It was created as part of a workshop I presented to my coworkers to illustrate practical uses of these new features.

About the Workshop

The workshop walked through Java 8’s key innovations with hands-on code examples, covering language enhancements, API improvements, and functional programming capabilities.

Each Java class in this repository focuses on a specific feature, keeping the code minimal and easy to understand.

Covered Features

Some of the Java 8 innovations demonstrated include:

• Lambda Expressions – Concise way to pass behavior
• Method References – Simplified lambda syntax
• New Date and Time API (java.time package)
• Streams API – Declarative data processing (map(), filter(), reduce(), etc.)
• Optional Class – Handling potentially null values
• Map API Enhancements – forEach(), computeIfAbsent(), etc.
• Concurrency enhancements – CompletableFuture for async programming, parallel streams, and new ConcurrentHashMap methods
