+# [[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):
+```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);
+}
+```

+## ✅ 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 Methods Return]], [[Java Scope]], [[Java Recursion]]
+- **참조 맥락:** 동일 이름의 메서드를 매개변수로 구분 — Scope/Recursion 챕터로 이어짐.
