Java Output

🎯 한 줄 통찰 (One-line insight)

println() and print() differ only in whether a newline follows — but the tutorial deliberately sticks to println() throughout for readability, treating print() as a rarely-needed variant. [S1]

🧠 핵심 개념 (Core concepts)

• println() — prints text/values, adding a newline after each call. [S1]
• Double quotes required — text must be wrapped in ""; omitting them is a compile error. [S1]
• print() — same as println() but does NOT add a trailing newline. [S1]

📖 세부 내용 (Details)

• Multiple println calls: System.out.println("Hello World!"); System.out.println("I am learning Java."); — each on its own line. [S1]
• print() without newline: System.out.print("Hello World! "); System.out.print("I will print on the same line.");. [S1]

⚖️ 모순 및 업데이트 (Contradictions & updates)

소스에서 모순되는 정보는 발견되지 않음.

🛠️ 적용 사례 (Applied in summary)

현재 발견된 실제 적용 사례가 없습니다 — 이 튜토리얼 전체에서 println()만 일관되게 사용한다고 명시됨. [S1]

💻 코드 패턴 (Code patterns)

print() without a trailing newline (Java):

System.out.print("Hello World! ");
System.out.print("I will print on the same line.");
