Streams & Lambdas

Java 8 introduced the biggest change in the language’s history: Functional Programming. This module covers how to write declarative, concise, and parallelizable code using Lambdas and the Stream API.

1. Functional Programming

Master the building blocks: Lambda Expressions, Functional Interfaces, and Method References. Understand how invokedynamic makes them efficient.

2. Advanced Stream Ops

Deep dive into the Stream pipeline. Learn map, filter, flatMap, and advanced Collectors like groupingBy. Visualize data flow with marble diagrams.

3. Parallel Streams

Unlock multi-core performance with the Fork/Join framework. Learn the NQ Model to decide when parallelism is worth the overhead and avoid race conditions.

4. Module Review

Review key concepts with interactive flashcards and a comprehensive cheat sheet.
