Score: 32/100 (v2, computed 2026-09-02T17:46:02.011165+00:00)
- activity 0, release rhythm 35, longevity 100
- inputs: {"age_days": 4095, "days_push": 1766, "days_rel": null, "gap_med": null, "n_releases_24m": 0}
- flags: no_releases
- formula: round(0.45*activity + 0.35*rhythm + 0.20*longevity); archived -> min(score, 10)

## What it is
A collection of Java example code and accompanying tutorial articles covering core Java topics such as syntax, OOP, collections, IO, reflection, threads, and networking. It is designed as a hands-on learning resource for beginners and for consolidating core Java knowledge.

## Use cases
- learn java core concepts with runnable examples
- understand how java collections like hashmap and arraylist work internally
- study java io streams through source-code walkthroughs
- review java basics like oop, strings, and reflection
- see a simple rpc implementation built with dynamic proxies and sockets
- find beginner java practice code with matching test cases

## When to choose
- you are a Java beginner wanting example-driven learning
- you want to consolidate core Java knowledge with code plus tests
- you prefer tutorials paired with a companion GitHub repository

## When to avoid
- you need production-ready libraries or frameworks
- you want coverage of modern Java features like Java 8+ modules, which are incomplete
- you need an actively maintained project with recent updates

## Facets
- artifact type: learning-resource
- maturity: maintenance
- function: developer-tools, testing
- domain: education, programming-languages, tutorials, developer-tools
- platform: jvm, cross-platform
- tags: java-core, learning-examples, beginner-friendly, collections, io, concurrency, reflection, rpc-example, chinese-language
