# [[Java Tutorial]]

## 🎯 한 줄 통찰 (One-line insight)
Map of Content (MOC) for the W3Schools Java Tutorial — the root that links every core-Java-language knowledge page in this topic folder. [S1]

## 🧠 핵심 개념 (Core concepts)
- This folder (`Topic_Java`) wikifies the core Java language tutorial, one knowledge page per document, in P-Reinforce v3.1 format — same convention as `Topic_SQL` / `Topic_Python` / `Topic_HTML` / `Topic_CSS` / `Topic_JavaScript`. [S1]
- Scope: **tutorial + "Real-Life Examples" pages only**. Explicitly **excluded**: reference dumps (`ref_keyword_*`, `ref_string_*`, `ref_math_*`, `ref_arraylist_*`, `ref_linkedlist_*`, `ref_hashmap_*`, `ref_scanner_*`, `ref_arrays_*`, and the `java_ref_*` index pages for each), How-To recipes (`java_howto_*` and `java_howtos.asp` — separate "HOW TO" category), Code Challenge companion pages (`java_challenges_*`), and meta pages (Certificate/Compiler/Exercises/Quiz/Server/Syllabus/Study Plan/Interview Q&A/Videos/Examples). [S1]
- **Progress:** **118 of 118 planned docs complete — Java category done.**
- Every page roots its Knowledge Graph back to this `[[Java Tutorial]]` node.
