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):
int age = 18;
System.out.println(age >= 18); // true, old enough to vote
int passwordLength = 5;
System.out.println(passwordLength >= 8); // false, too short
