계: Code Quality

코드 품질이 낮으면 예측할 수 없는 동작이 발생합니다. 사용자 입장에서는 사용 편의성이 떨어지는 것으로 나타나는 경우가 많습니다. 공격자에게는 예상치 못한 방법으로 시스템에 부담을 줄 수 있는 기회가 됩니다.

Code Correctness: Class Does Not Implement Cloneable

Abstract
이 클래스는 clone() 메서드를 구현하지만 Cloneable 인터페이스는 구현하지 않습니다.
Explanation
프로그래머는 이 클래스가 clone()이라는 메서드를 구현하기 때문에 Cloneable 인터페이스를 구현하도록 할 생각이었던 것 같습니다. 하지만 클래스는 Cloneable 인터페이스를 구현하지 않고 clone() 메서드는 올바로 동작하지 않습니다.

예제 1: 다음 클래스에서 clone()을 호출하면 CloneNotSupportedException.이 발생합니다.


public class Kibitzer {
  public Object clone() throws CloneNotSupportedException {
    ...
  }
}
