如何在静态方法中实例化非静态内部类

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;
   }
}

这部分代码很好，但我是无法在主方法中实例化'in'，如 in = new Inner（），因为它显示非静态字段无法在静态上下文中引用。我能用它做什么？我不想让我的内部类静态。

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

推荐答案

你也必须引用另一个外部类。

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();
