在throw参数周围加上括号是否有效？ [英] Does adding parentheses around a throw argument have any effect?

问题描述

写作上有区别吗？

throw SomeException;

和

throw(SomeException);

我已经看到一些消息源声称由于某种原因，后者（带括号）不是一个好选择

I have seen some sources that claim the latter (with parentheses) is not a good option for some reason but alas I can not recall where I've seen this.

推荐答案

应该不要除括号外，两个表达式之间的功能差异。我从未听说过任何明确的理由说明为什么一个人应该优于另一个人。

There should not be any functionality difference between the two expressions apart from the parentheses. I have never heard of any clear reason that says why one should be superior to the other.

对我来说，第一个选项看起来更直观，因为它不包含不必要的括号。 ！

To me the first option looks more intuitive as it does not include the unnecessary parentheses!

也如@Pubby在评论中所述，不要与需要括号的throw说明符混淆（ throw 可能 已弃用）。

Also as @Pubby said in the comment, one should not confuse with the throw specifier which requires parentheses (throw specifier is probably deprecated).
