Java Methods

🎯 한 줄 통찰 (One-line insight)

static on a method means it belongs to the CLASS itself, not to any object instance — a distinction the tutorial defers explaining fully until objects are introduced later, but flags immediately since every method example so far uses it. [S1]

🧠 핵심 개념 (Core concepts)

• Method — a named, reusable block of code that runs only when called; also called a function. [S1]
• Purpose — code reuse: define once, use many times. [S1]
• Declaration inside a class — static void myMethod() { ... }. [S1]
• static — the method belongs to the class, not an object instance (elaborated later with OOP). [S1]
• void — signals no return value. [S1]
• Calling — myMethod(); — can be called repeatedly. [S1]

📖 세부 내용 (Details)

• Definition: public class Main { static void myMethod() { // code } }. [S1]
• Call and output: static void myMethod() { System.out.println("I just got executed!"); } public static void main(String[] args) { myMethod(); }. [S1]
• Repeated calls: calling myMethod(); three times inside main prints the message three times. [S1]

⚖️ 모순 및 업데이트 (Contradictions & updates)

🛠️ 적용 사례 (Applied in summary)

현재 발견된 실제 적용 사례가 없습니다 — 코드 재사용의 기본 단위이며, 파라미터/반환값/오버로딩으로 확장된다. [S1]

💻 코드 패턴 (Code patterns)

Basic method definition and repeated call (Java):

public class Main {
    static void myMethod() {
        System.out.println("I just got executed!");
    }
    public static void main(String[] args) {
        myMethod();
        myMethod();
        myMethod();
    }
}
