# [[Java Comments]]

## 🎯 한 줄 통찰 (One-line insight)
Unlike Python, Java has a REAL native multi-line comment syntax (`/* ... */`) — no unassigned-string workaround needed. [S1]

## 🧠 핵심 개념 (Core concepts)
- **Single-line comment (`//`)** — everything from `//` to end of line is ignored. [S1]
- **Multi-line comment (`/* ... */`)** — everything between the markers is ignored, natively supported. [S1]
- **Style convention** — `//` for short comments, `/* */` for longer ones. [S1]

## 📖 세부 내용 (Details)
- Single-line before code: `// This is a comment` then `System.out.println("Hello World");`. [S1]
- Single-line at end of line: `System.out.println("Hello World"); // This is a comment`. [S1]
- Multi-line block: `/* The code below will print the words Hello World to the screen, and it is amazing */`. [S1]

## ⚖️ 모순 및 업데이트 (Contradictions & updates)
소스에서 모순되는 정보는 발견되지 않음.

## 🛠️ 적용 사례 (Applied in summary)
현재 발견된 실제 적용 사례가 없습니다 — 코드 문서화 및 디버깅 시 코드 일부 비활성화에 표준적으로 쓰인다. [S1]

## 💻 코드 패턴 (Code patterns)
Native multi-line comment (Java):
```java
/* The code below will print the words Hello World
   to the screen, and it is amazing */
System.out.println("Hello World");
```
