+# [[Java Operators Logical]]
+
+## 🎯 한 줄 통찰 (One-line insight)
+Java's logical operators use symbolic form (`&&`, `||`, `!`) rather than Python's keyword form (`and`, `or`, `not`) — same semantics, different syntax, a common point of confusion when switching between the two languages. [S1]
+
+## 🧠 핵심 개념 (Core concepts)
+- **`&&` (logical AND)** — true if BOTH statements are true. [S1]
+- **`||` (logical OR)** — true if AT LEAST ONE statement is true. [S1]
+- **`!` (logical NOT)** — reverses the result. [S1]
+
+## 🧩 추출된 패턴 (Extracted patterns)
+- **Access-control logic via boolean combination** — `isLoggedIn && !isAdmin` ("regular user"), `isLoggedIn || isAdmin` ("has access") shows how login/permission checks compose from simple booleans using logical operators. [S1]
+
+## 📖 세부 내용 (Details)
+- Login/access check: `boolean isLoggedIn = true; boolean isAdmin = false; System.out.println("Regular user: " + (isLoggedIn && !isAdmin)); System.out.println("Has access: " + (isLoggedIn || isAdmin));`. [S1]
+
+## ⚖️ 모순 및 업데이트 (Contradictions & updates)
+- **Python과 문법 차이**: Python은 `and`/`or`/`not` 키워드를 쓰지만 Java는 `&&`/`||`/`!` 기호를 쓴다. [S1]
+
+## 🛠️ 적용 사례 (Applied in summary)
+현재 발견된 실제 적용 사례가 없습니다 — 로그인 상태/권한 확인처럼 여러 불리언을 조합하는 실전 패턴이다. [S1]
+
+## 💻 코드 패턴 (Code patterns)
+Login/permission check via logical operators (Java):
+```java
+boolean isLoggedIn = true;
+boolean isAdmin = false;
+System.out.println("Regular user: " + (isLoggedIn && !isAdmin));
+System.out.println("Has access: " + (isLoggedIn || isAdmin));
+```
+
+## ✅ 검증 상태 및 신뢰도
+- **상태:** draft
+- **검증 단계:** conceptual
+- **출처 신뢰도:** B (W3Schools — widely used educational reference, not a primary standards body)
+- **신뢰 점수:** 0.90
+- **중복 검사 결과:** 신규 생성 (New discovery)
+
+## 🔗 지식 그래프 (Knowledge Graph)
+- **상위/루트:** [[Java Tutorial]]
+- **관련 개념:** [[Java Operators Comparison]], [[Java If Else]], [[Python Operators Logical]]
+- **참조 맥락:** Python의 and/or/not과 동일한 개념이지만 기호(&&/||/!)로 표기.
