在java編程領域中，將java.lang.runtimeException從java.lang.exection

Defining the Distinction

The fundamental distinction between RuntimeException and Exception lies in their nature as checked vs. unchecked exceptions.由java.lang.exception舉例說明的檢查例外，需要進行編譯器審查。程序員必須明確處理它們或聲明拋出檢查異常的方法。這種方法旨在防止由於未經處理的錯誤而導致的意外程序終止。

相反，RuntimeException表示未檢查的異常，這些異常在編譯時未檢測到。 These exceptions typically occur due to runtime errors such as null pointer exceptions or array index out-of-bounds errors, which can often be prevented programmatically.

Deciding Which to Extend

When creating custom exceptions, the choice between extending RuntimeException or Exception depends on the nature of the error being handled. Here are some general guidelines:

Extend RuntimeException:

For exceptions that can be prevented during program execution (e.g., null pointer exceptions)

• When a clean code style is preferred 擴展異常：

  ，該程序應迫使該程序迫使該程序終止（例如，致命的系統錯誤）在與noffere decords Indrece drecect condection drecect condece drecect condece dreceed forke code時異常
  • 理解RuntimeTimeException和Exception之間的區別對於在Java Programing中的有效錯誤處理至關重要。通過仔細考慮上面概述的方案，您可以做出明智的決定，以了解在創建自定義異常時要擴展哪種異常類型。
