如何在静态方法中实例化非静态内部类? [英] How to instantiate non static inner class within a static method?

问题描述

我有以下代码:

public class MyClass {

   class Inner {
     int s, e, p;
   }

   public static void main(String args[]) {
     Inner in;
   }
}

到目前为止，代码还不错，但是我无法在像in = new Inner()这样的主要方法中实例化"in"，因为它显示了non static field cannot be referenced in static context.

Up to this part the code is fine, but I am not able to instantiate 'in' within the main method like in = new Inner() as it is showing non static field cannot be referenced in static context.

我可以怎么做?我不想让我的Inner类静态.

What is the way I can do it? I do not want to make my Inner class static.

推荐答案

您还必须引用其他外部类.

You have to have a reference to the other outer class as well.

Inner inner = new MyClass().new Inner();

如果Inner是静态的，那么它将是

If Inner was static then it would be

Inner inner = new MyClass.Inner();
