Question

Consider the following code

    class InnerClass{
        int x;
        int y;
        void calculateX(){
            x = y+z;//I want to acce         


        

Answer 1

You could store a reference to itself in OuterClass and use it from InnerClass to access its fields, like so:

class OuterClass{
    OuterClass reference = this;
    ...
    class InnerClass {
       ...
       void calculateX() {
           reference.y; // OuterClass.y
           this.y; // InnerClass.y
