最后在异常处理 [英] finally in exception handling

问题描述

推荐答案

例如，如果你打开了一个文件，你应该在 finally 块，以确保它始终关闭;如果在 try 块中关闭它，早期的异常将导致执行直接跳转到 catch 块并跳过关闭文件。

For example, if you have opened a file, you should close it in the finally block to ensure that it will always be closed; if you closed it in the try block, an earlier exception would cause execution to jump straight to the catch block and skip closing the file.
