该异常会向外传播并向上传播，并将(可以)在更高级别进行处理.

That exception propagates out and up, and will (can) be handled at a higher level.

您的 finally 块将不会在抛出异常的点之后完成.

Your finally block will not be completed beyond the point where the exception is thrown.

如果在处理较早的异常期间执行 finally 块，则第一个异常将丢失.

If the finally block was executing during the handling of an earlier exception then that first exception is lost.
