### Java에서 다중상속을 지원하지 않는 이유는 무엇인가요.

- C++에서는 한 클래스에서 직간접적으로 하나 이상의 클래스를 상속할 수 있으며 이를 __다중상속__ 이라 한다.
- 그러나 두 부모 클래스(House, Office)가 한 클래스로(Place)부터 파생된 클래스인 경우 다중상속을 쓰면 애매한 상황이 발생한다.
1. 상속받은 House, Office 클래스에 같은 이름의 멤버가 존재할 가능성
2. 하나의 클래스(Place)를 간접적으로 두 번 이상 상속받을 가능성이 있습니다.
3. 가상 클래스가 아닌 기초 클래스를 다중 상속하면, 기초 클래스 타입의 포인터로 파생 클래스를 가리킬 수 없음

<br />

이러한 문제를 죽음의 다이아몬드(the Deadly Diamond of Death), 다이아몬드 문제(diamond problem)라고 한다. 다아아몬드 문제를 막기 위해서 다중상속을 막는다.
