# [[Java Operators Comparison]]

## 🎯 한 줄 통찰 (One-line insight)
Comparison operators always resolve to a boolean, which is exactly what If...Else and loop conditions consume — comparisons are the bridge between raw values and program control flow. [S1]

## 🧠 핵심 개념 (Core concepts)
- **Comparison operators** — `==`, `!=`, `>`, `<`, `>=`, `<=`; return true or false. [S1]
- **Purpose** — help programs find answers and make decisions. [S1]

## 📖 세부 내용 (Details)
- Basic comparison: `int x = 5; int y = 3; System.out.println(x > y); // true`. [S1]
- Voting age check: `int age = 18; System.out.println(age >= 18); // true`. [S1]
- Password length check: `int passwordLength = 5; System.out.println(passwordLength >= 8); // false`. [S1]

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

## 🛠️ 적용 사례 (Applied in summary)
현재 발견된 실제 적용 사례가 없습니다 — 투표 연령/비밀번호 길이 검증처럼 실전 조건 검사의 기초 도구다. [S1]

## 💻 코드 패턴 (Code patterns)
Real-world condition checks (Java):
```java
int age = 18;
System.out.println(age >= 18);  // true, old enough to vote

int passwordLength = 5;
System.out.println(passwordLength >= 8);  // false, too short
```
