# [[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]

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

## 🛠️ 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):
```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);
}
```
