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):

/* The code below will print the words Hello World
   to the screen, and it is amazing */
System.out.println("Hello World");
