## What it is
A tutorial series of articles explaining Java 8 functional programming, Lambda expressions, and the Streams API, including their underlying implementation principles. It covers usage, stream pipelines, parallel streams, and performance benchmarks.

## Use cases
- learn how Java lambda expressions work internally
- understand how the Streams API is implemented
- learn stream pipeline and parallel stream internals
- compare stream performance against traditional loops
- migrate from anonymous inner classes to lambdas
- learn Java 8 collection framework enhancements

## When to choose
- you want a deep, internals-focused explanation of Java lambdas and streams
- you prefer reading a structured article series with benchmarks
- you are comfortable reading Chinese-language technical content

## When to avoid
- you need a quick API reference or official documentation
- you want an interactive course or video tutorials
- you need coverage of Java versions beyond 8 features

## Facets
- artifact type: learning-resource
- maturity: maintenance
- function: developer-tools
- domain: programming-languages, tutorials, developer-tools
- platform: jvm
- tags: java-8, lambda-expressions, streams-api, functional-programming, tutorial-series, chinese-language
