Java: How to get immediate parent(who is not the top level class) from an inner class? -

i'm aware differences between static nested class , inner class in java. i'm talking inner class. i'm aware can use "outerclass.this" outer class inner class.

like directory, there 2 ways navigate: absolute , relative. example: "/aaa/bbb/ccc/ddd", if i'm inside folder "ccc" , want refer "bbb", can either: "cd /aaa/bbb" or "cd ..".

now comes java inner classes.

class aaa{     bbb b = new bbb();     class bbb{         ccc c = new ccc();         //ccc c = new ccc(b);         class ccc{             //second version             //bbb parent = null             //ccc(bbb parent_){             //    parent = parent_;             //}             ddd d = new ddd();             bbb getparent(){                 return aaa.this.b;    //i know work                 //or return parent; if using second version             }             class ddd{             }             }     } } 

i've provided 2 versions: aaa.this.b , introduce member variable "parent", assigned value parameter of constructor.

my question: if don't introduce member variable, may use relative way immediate parent inner class? (like cd ..)

you can use bbb.this directly refer enclosing instance of class bbb.
