如何在Java中返回对象数组?

How do I return an array of objects in java?

推荐答案

好吧，您实际上只能将 references 的数组返回给对象-Java中没有任何表达式可以对对象本身求值.话虽如此，返回对象引用数组很容易:

Well, you can only actually return an array of references to objects - no expressions in Java actually evaluate to objects themselves. Having said that, returning an array of Object references is easy:

 public Object[] yourMethod()
 {
     Object[] array = new Object[10];
     // Fill array
     return array;
 }

(要彻底研究，您要将 reference 返回到对象引用数组.)

(To be utterly pedantic about it, you're returning a reference to an array of object references.)
