在java单例中获取内部类的实例

Question

I have the following arrangement (not showing all fields and methods):

public class MyClass implements myClassInterface{

    public static MyClass getInstance(){
       return INSTANCE;
    }

    public class Inner implements innerStuff{
        @Override
         public void doInnerWork(Object param){
         }
    }
}

I need to access doInnerWork(param) . How do I do that? I try many things but they all fail including:

new (MyClass.getInstance().Inner()).doInnerWork(param);

thanks for helping.

Answer 1

MyClass.getInstance().new Inner().doInnerWork(param);
请注意，这将每次创建一个新的内部类（它不会是单例）。

Answer 2

To create an instance of a nested class Inner , where you want it to be nested inside some object obj , the syntax is

obj.new Inner()

So in your case you probably want

MyClass.getInstance().new Inner().doInnerWork(param);

I'm not saying this will give you the results you want, but that's the syntax.
