在 void 方法中返回 void? [英] return void in a void method?

问题描述

我知道我可以做到:

void someMethod(){
 return;
 }

但我在

void someMethod(){
return void;
}

为什么不允许后者?这对我来说更有意义.

Why is the latter not allowed? It makes more sense to me.

我知道什么是 void 方法，而且我根本不需要从它返回(并且可能不应该，在大多数情况下)但我不明白为什么我不能返回 void从空方法.在我看来，如果您能够编写 return; ，则方法声明中不应该有关键字(如构造函数).

I know what a void method is, and that I don't have to return from it at all(and probably shouldn't, in most cases) but I don't understand why I can't return void from a void method. In my opinion, there should be no keyword in the method declaration (like constructors) if the you are able to write return;.

推荐答案

我认为两者都应避免.我更喜欢这个:

I think both are to be shunned. I prefer this:

void someMethod() {
    // do stuff; no return at bottom
}

我愿意让您在 JDK 源代码中找到许多类似这样的方法.

I'd be willing to be that you'd find lots of methods in the JDK source code that look like this.
