java - 正确使用 RuntimeException？

Question

Answer 1

来自 Unchecked Exceptions -- The Controversy :

If a client can reasonably be expected to recover from an exception, make it a checked exception. If a client cannot do anything to recover from the exception, make it an unchecked exception.

请注意，未经检查的异常是从 RuntimeException 派生的异常。并且检查异常是从 Exception 派生的异常.

如果客户端无法从异常中恢复，为什么要抛出 RuntimeException？文章解释:

Runtime exceptions represent problems that are the result of a programming problem, and as such, the API client code cannot reasonably be expected to recover from them or to handle them in any way. Such problems include arithmetic exceptions, such as dividing by zero; pointer exceptions, such as trying to access an object through a null reference; and indexing exceptions, such as attempting to access an array element through an index that is too large or too small.
