Java Break Continue

🎯 한 줄 통찰 (One-line insight)

break and continue are opposite loop-control tools — break stops the loop completely, continue skips only the current iteration and keeps looping — and they compose cleanly, as shown by the negative-number-skip/zero-stop real-life example combining both in one loop. [S1]

🧠 핵심 개념 (Core concepts)

• break — already seen exiting switch statements; also exits a loop entirely. [S1]
• continue — skips the rest of the current iteration and moves to the next one. [S1]
• Mnemonic — "break = stop the loop completely. continue = skip this round, but keep looping." [S1]
• Works in for and while loops — both statements apply to any loop type. [S1]
• Combinable — a single loop can use both break and continue for different conditions. [S1]

📖 세부 내용 (Details)

• Break in for: for (int i = 0; i < 10; i++) { if (i == 4) { break; } System.out.println(i); }. [S1]
• Continue in for: for (int i = 0; i < 10; i++) { if (i == 4) { continue; } System.out.println(i); }. [S1]
• Combined: for (int i = 0; i < 6; i++) { if (i == 2) { continue; } if (i == 4) { break; } System.out.println(i); } — skips 2, stops at 4. [S1]
• Break in while: int i = 0; while (i < 10) { System.out.println(i); i++; if (i == 4) { break; } }. [S1]
• Continue in while: int i = 0; while (i < 10) { if (i == 4) { i++; continue; } System.out.println(i); i++; }. [S1]
• Real-life array processing: int[] numbers = {3, -1, 7, 0, 9}; for (int n : numbers) { if (n < 0) { continue; } if (n == 0) { break; } System.out.println(n); } — skips negatives, stops at zero. [S1]

🛠️ 적용 사례 (Applied in summary)

현재 발견된 실제 적용 사례가 없습니다 — 음수 건너뛰고 0에서 멈추는 배열 처리 예제는 필터링+조기종료 로직의 표준 패턴이다. [S1]

💻 코드 패턴 (Code patterns)

Skip negatives, stop at zero (Java):

int[] numbers = {3, -1, 7, 0, 9};
for (int n : numbers) {
    if (n < 0) {
        continue; // skip negative numbers
    }
    if (n == 0) {
        break; // stop loop when zero is found
    }
    System.out.println(n);
}
