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 Overloading

🎯 한 줄 통찰 (One-line insight)

Method overloading is explicitly framed as the FIX for a code smell — the tutorial first shows two differently-named methods (plusMethodInt, plusMethodDouble) doing the same conceptual job, then demonstrates overloading them under one shared name (plusMethod) as the better design. [S1]

🧠 핵심 개념 (Core concepts)

Method overloading — multiple methods sharing the same name but differing in parameter number/type. [S1]
Compiler resolves by signature — Java picks the right overload based on argument types/count at the call site. [S1]
Design motivation — avoids duplicating near-identical methods with different names just to handle different types. [S1]
Rule — same name is legal only if the number and/or type of parameters differs. [S1]

📖 세부 내용 (Details)

Before overloading (bad pattern): static int plusMethodInt(int x, int y) { return x + y; } static double plusMethodDouble(double x, double y) { return x + y; }. [S1]
After overloading (good pattern): static int plusMethod(int x, int y) { return x + y; } static double plusMethod(double x, double y) { return x + y; }. [S1]
Usage: int myNum1 = plusMethod(8, 5); double myNum2 = plusMethod(4.3, 6.26); — the correct overload is chosen automatically based on argument types. [S1]

⚖️ 모순 및 업데이트 (Contradictions & updates)

소스에서 모순되는 정보는 발견되지 않음.

🛠️ 적용 사례 (Applied in summary)

현재 발견된 실제 적용 사례가 없습니다 — int/double 등 타입별로 별도 메서드명을 두는 대신 오버로딩으로 통합하는 설계 개선 사례다. [S1]

💻 코드 패턴 (Code patterns)

Overloaded plusMethod for int and double (Java):

static int plusMethod(int x, int y) {
    return x + y;
}
static double plusMethod(double x, double y) {
    return x + y;
}
public static void main(String[] args) {
    int myNum1 = plusMethod(8, 5);
    double myNum2 = plusMethod(4.3, 6.26);
}
