# [[Java Operators Assign]]

## 🎯 한 줄 통찰 (One-line insight)
Every compound assignment operator (`+=`, `-=`, `&=`, `>>=`, etc.) is pure shorthand for `x = x <op> value` — Java has 11 of them, covering arithmetic, bitwise, and shift operations, all following the identical expansion rule. [S1]

## 🧠 핵심 개념 (Core concepts)
- **`=`** — basic assignment. [S1]
- **Compound assignment operators** — `+=`, `-=`, `*=`, `/=`, `%=`, `&=`, `|=`, `^=`, `>>=`, `<<=`, each a shorthand for `x = x <op> value`. [S1]

## 📖 세부 내용 (Details)
- Basic: `int x = 10;`. [S1]
- Compound: `x += 5;` (same as `x = x + 5;`). [S1]
- Real-life savings tracker: `int savings = 100; savings += 50; System.out.println("Total savings: " + savings);`. [S1]

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

## 🛠️ 적용 사례 (Applied in summary)
현재 발견된 실제 적용 사례가 없습니다 — 저축액 누적 추적처럼 값을 점진적으로 증가/감소시키는 패턴에 표준적으로 쓰인다. [S1]

## 💻 코드 패턴 (Code patterns)
Compound assignment for accumulation (Java):
```java
int savings = 100;
savings += 50;  // same as: savings = savings + 50
System.out.println("Total savings: " + savings);
```
