是否可以顯式訪問包含類的嵌套類的實例成員？

Question

是否有在Java關鍵字，以允許含有實例的成員的顯式調用（或它的超類的）從嵌套類內？

情景

public class Superclass { 
    public void doSomething() { 
     // do something that's of interest to the superclass 
    } 
} 

public class Subclass extends Superclass { 
    @Override 
    public void doSomething() { 
     // do something that's of interest to the subclass 
     // possibly call super.doSomething() 
    } 

    private class NestedClass { 
     private void doSomething() { 
      // do something that's of interest to the nested class 
      // calling doSomething() here without an explicit scope 
      // specifier results in a stack overflow 
     } 

     private void doSomethingElse() { 
      if (somethingOfInterestToTheSubclassIsNotImportant) { 
       // just invoke the superclass's doSomething() method 
      } else { 
       // invoke the subclass's doSomething() method 
      } 
     } 
    } 
}

哦，完全。只需使用Subclass.this.doSomething()或Subclass.super.doSomething()即可獲取超類方法。
