（obj == null）vs（null == obj）？ [英] (obj == null) vs (null == obj)?

问题描述

我的老板说我应该使用 null == obj ，因为它比 obj == null 他不记得为什么要这样做。是否有任何理由使用 null == obj ？

我觉得它在某种程度上...对面！

My boss said I should use null == obj, because it's better than obj == null, but he didn't remember why to do this. Is there any reason for using null == obj?

推荐答案

而是通过键入 obj = null 将 null 更改为 obj 然而，这是从C时代的回忆，在java中，这是不可能的，因为 = 表达式返回赋值的右边。因为 null 不是 boolean ，编译器会抱怨。

You can't accidently assign null to obj by typing obj = null instead. However, that's a reminiscence from C times, in java, it is not possible, as the = expression returns the right hand side of the assignment. As null is not a boolean, the compiler will complain.

我会尝试向我的老板解释一次，展示它。如果他仍然不同意你的话，只要这样做。这是一个与你的老板打架的小东西。

I would try to explain it to my boss once, demonstrate it. If he still doesn't agree with you, just do it. It's a petty thing to fight about with your boss.
