在java编程领域中，将java.lang.runtimeException从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举例说明的检查例外，需要进行编译器审查。程序员必须明确处理它们或声明抛出检查异常的方法。这种方法旨在防止由于未经处理的错误而导致的意外程序终止。

相反，RuntimeException表示未检查的异常，这些异常在编译时未检测到。 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 扩展异常：

  ，该程序应迫使该程序迫使该程序终止（例如，致命的系统错误）在与noffere decords Indrece drecect condection drecect condece drecect condece dreceed forke code时异常
  • 理解RuntimeTimeException和Exception之间的区别对于在Java Programing中的有效错误处理至关重要。通过仔细考虑上面概述的方案，您可以做出明智的决定，以了解在创建自定义异常时要扩展哪种异常类型。
