界: Errors
錯誤和錯誤處理代表一種 API 類別。與錯誤處理相關的錯誤非常普遍，所以它們應該擁有自己的特殊領域。如同「API 濫用」，有兩種方法可以引入與錯誤相關的安全漏洞：最常見的一種方法是不當處理錯誤 (或根本沒有處理)。第二種是產生錯誤，這些錯誤不是給的資訊太多 (給可能的攻擊者)，就是問題難以處理。
Poor Error Handling: Program Catches NullPointerException
Abstract
一般而言，捕捉
NullPointerException 不是個好方法。Explanation
通常在以下三個情況，程式設計師會擷取
1.程式包含了 Null 指標解除參照。擷取異常狀況的結果比修復基本問題還要簡單。
2. 程式明確的拋出了
3. 程式碼是測試代碼的一部分，它在測試的類別中提供了非預期的輸入。
在上述三種情況中，只有最後一種是可接受的。
範例：以下程式碼錯誤地擷取了
NullPointerException： 1.程式包含了 Null 指標解除參照。擷取異常狀況的結果比修復基本問題還要簡單。
2. 程式明確的拋出了
NullPointerException 異常狀況來提醒出現錯誤情況。3. 程式碼是測試代碼的一部分，它在測試的類別中提供了非預期的輸入。
在上述三種情況中，只有最後一種是可接受的。
範例：以下程式碼錯誤地擷取了
NullPointerException。
try {
mysteryMethod();
}
catch (NullPointerException npe) {
}
