界: Code Quality

コードの質が低いと、予測できない動作につながります。ユーザーの視点には、それがしばしば使い勝手の悪さとなって現れます。攻撃者にとっては、予期せぬ方法でシステムにストレスを与える機会となります。

Code Correctness: Class Does Not Implement Cloneable

Java/JSP

Abstract

このクラスは clone() メソッドを実装しますが、Cloneable インターフェイスは実装しません。

Explanation

clone() と名付けられたメソッドを実装するため、プログラマはこのクラスで Cloneable インターフェイスの実装を意図したようです。しかし、クラスは Cloneable インターフェイスを実装せず、clone() メソッドは正しく動作しません。

例 1: このクラスに clone() をコールすると、結果として CloneNotSupportedException. になります。


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