Antigravity Agent e9cbf23ab5 docs(10_Wiki): Dev 폴더 누락분 반영 — Topic_Programming으로 통합
이전 재구성 작업에서 Dev/ 폴더가 누락되었던 것을 반영.

- Dev/Topic_Programming(중첩 폴더, 78개)은 Dev 자체 최상위 폴더들
  (Architecture/Conventions/Engineering_Intelligence 등)과 완전 중복이라 제거.
- Dev 최상위 엔지니어링 지식 폴더(Architecture/Conventions/Engineering_Intelligence/
  Failure_Library/Generalized_Principles/Language/Pattern_Catalog/Platform_Guides/
  Subsystems, 77개)는 이미 Topic_Programming/Topic_Programming에 더 최신 버전이
  존재해 중복 제거(고유 콘텐츠 1개는 예외 처리하여 이동 보존).
- Dev의 W3Schools 언어 튜토리얼 폴더(Topic_C/CPP/CSS/CSharp/HOWTO/HTML/Java/
  JavaScript/PHP/Python/SQL/W3CSS, 1201개)는 전부 Topic_Programming 하위로 이동.
- 에이전트 운영 상태(.astra/docs)는 그대로 유지, 콘텐츠 폴더만 정리.
- Topic_Programming 최종 문서 수: 2784 → 3985.

Java Methods

🎯 한 줄 통찰 (One-line insight)

static on a method means it belongs to the CLASS itself, not to any object instance — a distinction the tutorial defers explaining fully until objects are introduced later, but flags immediately since every method example so far uses it. [S1]

🧠 핵심 개념 (Core concepts)

  • Method — a named, reusable block of code that runs only when called; also called a function. [S1]
  • Purpose — code reuse: define once, use many times. [S1]
  • Declaration inside a classstatic void myMethod() { ... }. [S1]
  • static — the method belongs to the class, not an object instance (elaborated later with OOP). [S1]
  • void — signals no return value. [S1]
  • CallingmyMethod(); — can be called repeatedly. [S1]

📖 세부 내용 (Details)

  • Definition: public class Main { static void myMethod() { // code } }. [S1]
  • Call and output: static void myMethod() { System.out.println("I just got executed!"); } public static void main(String[] args) { myMethod(); }. [S1]
  • Repeated calls: calling myMethod(); three times inside main prints the message three times. [S1]

⚖️ 모순 및 업데이트 (Contradictions & updates)

소스에서 모순되는 정보는 발견되지 않음.

🛠️ 적용 사례 (Applied in summary)

현재 발견된 실제 적용 사례가 없습니다 — 코드 재사용의 기본 단위이며, 파라미터/반환값/오버로딩으로 확장된다. [S1]

💻 코드 패턴 (Code patterns)

Basic method definition and repeated call (Java):

public class Main {
    static void myMethod() {
        System.out.println("I just got executed!");
    }
    public static void main(String[] args) {
        myMethod();
        myMethod();
        myMethod();
    }
}
