界: Code Quality

程式碼品質不佳，會導致無法預料的行為。從使用者的角度來看，這通常表現為可用性不佳。對於攻擊者而言，這提供了以意想不到的方式向系統施加壓力的機會。

Code Correctness: Class Does Not Implement Cloneable

Abstract
此類別會執行 clone() 方法但不會執行 Cloneable 介面。
Explanation
程式設計師原本似乎想要為此類別執行 Cloneable 介面，因為它執行了名為 clone() 的方法。但是，此類別沒有執行 Cloneable 介面，且 clone() 方法將不會正確運作。

範例 1：為此類別呼叫 clone() 方法將導致 CloneNotSupportedException.

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