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 Anonymous]]
+
+## 🎯 한 줄 통찰 (One-line insight)
+An anonymous class body ends with a semicolon (`};`) — an easy detail to miss, since it's not closing a method or normal class, but terminating the object-creation STATEMENT `Animal myAnimal = new Animal() {...}` that happens to contain a class body inline. [S1]
+
+## 🧠 핵심 개념 (Core concepts)
+- **Anonymous class** — a nameless class defined and instantiated in the same expression. [S1]
+- **Use case** — overriding a method of an existing class/interface without writing a separate named class file. [S1]
+- **Extends a class** — `new Animal() { @Override method } ;` — creates a one-off subclass instance inline. [S1]
+- **Implements an interface** — the same syntax works to implement an interface on the fly. [S1]
+- **Required trailing semicolon** — closes the object-creation statement, not just the class body. [S1]
+
+## 📖 세부 내용 (Details)
+- Overriding a class method anonymously: `Animal myAnimal = new Animal() { public void makeSound() { System.out.println("Woof woof"); } };`. [S1]
+- Implementing an interface anonymously: `Greeting greet = new Greeting() { public void sayHello() { System.out.println("Hello, World!"); } };`. [S1]
+- Use cases listed: overriding a method without a new subclass, quickly implementing an interface, passing small behaviors as objects. [S1]
+
+## ⚖️ 모순 및 업데이트 (Contradictions & updates)
+소스에서 모순되는 정보는 발견되지 않음.
+
+## 🛠️ 적용 사례 (Applied in summary)
+현재 발견된 실제 적용 사례가 없습니다 — 일회성 동작(override/interface 구현)을 별도 파일 없이 즉석에서 정의하는 표준 패턴이다. [S1]
+
+## 💻 코드 패턴 (Code patterns)
+Anonymous class implementing an interface on the fly (Java):
+```java
+interface Greeting {
+    void sayHello();
+}
+Greeting greet = new Greeting() {
+    public void sayHello() {
+        System.out.println("Hello, World!");
+    }
+};
+greet.sayHello();
+```

+## ✅ 검증 상태 및 신뢰도
+- **상태:** draft
+- **검증 단계:** conceptual
+- **출처 신뢰도:** B (W3Schools — widely used educational reference, not a primary standards body)
+- **신뢰 점수:** 0.87
+- **중복 검사 결과:** 신규 생성 (New discovery)
+
+## 🔗 지식 그래프 (Knowledge Graph)
+- **상위/루트:** [[Java Tutorial]]
+- **관련 개념:** [[Java Interface]], [[Java Polymorphism]], [[Java Enums]]
+- **참조 맥락:** 일회성 클래스/인터페이스 구현 — Enums 챕터로 이어짐.
