'Fruit ...'是Java命名约定中的有效类名吗？(Is 'Fruit…' a valid class name in Java Naming convention?)

我是Java的初学者，在我探索的过程中，我看到了一个代码，它的用法是Fruit... fruitName ？ 我曾经在任何文档中看到过这样的用法，比如...

任何人都可以知道这个用途是什么以及如何使用？

I'm a beginner in Java, and while I was exploring I got to see a code which has the usage as Fruit... fruitName? I have ever seen such a usage in any documentation like ...

Can anyone know what and how the usage of this?

最满意答案

class Fruit { // Class implementation } public void extractJuice(Fruit... args) { // This method can take variable arguments of type Fruit }

所以你所看到的是变量参数的缩写。

其他参考文献： - 你什么时候在Java中使用varargs？

class Fruit { // Class implementation } public void extractJuice(Fruit... args) { // This method can take variable arguments of type Fruit }

So what you are looking at is varargs short for Variable Arguments.
