我有以下代码.我想掌握使用它创建内部类对象的外部类对象inner.我该怎么做？

public class OuterClass {

    public class InnerClass {
        private String name = "Peakit";
    }

    public static void main(String[] args) {
        OuterClass outer = new OuterClass();
        InnerClass inner = outer.new InnerClass();
       // How to get the same outer object which created the inner object back?
        OuterClass anotherOuter = ?? ;

        if(anotherOuter == outer) {
             System.out.println("Was able to reach out to the outer object via inner !!");
        } else {
             System.out.println("No luck :-( ");
        }
    }
}

编辑:嗯,你们中的一些人建议通过添加一个方法来修改内部类: …

我们如何访问外部类这个实例:例如in

Class A {

   Class B {

      this.helloB();
      (A's this).hello()
   }
}

我们如何在Java中访问A的这个实例

我想将在main方法中创建的确切实例传递给具有MPGui作为参数的新Executor.这可能吗？

public class MPGui {
  public MPGui() {
    //initialize GUI
  }

  public class ExecuteListener implements ActionListener {
    public void actionPerformed(ActionEvent e) {

      Executor execu = new Executor(MLA, /*the MPGUI() instance */);
      execu.execute();          
    }
  }

  public static void main(String[] args) {
    MPGui a = new MPGui();
  }
}
