How to set default value for a child class

[orchid egret]

I have a States class that has a couple of variables, and i have a child class that extends from the super class how can i set the variables in the child class so the superclass recognizes it, because right now if i use a method inside the superclass to access the variables inside the child class it returns a null

Well parent classes dont inherit from child classes.

[orchid egret]

so is it not possible to set the values without a constructor?

[dusk ether]

what do you mean? you can of course access all the variables of the super in the child class. Or what do you want to do?

[orchid egret]

so what i used to do is using this constructor to set the super values, is it possible to do the same thing without it being in a constructor?

[dusk ether]

just use super.

[orchid egret]

im so sorry im pretty new, why does this happen?

[chilly spire]

your fields in your superclass may not be private.
Here is a list of modifiers you can apply to fields with their resulting visibility

that means that for your subclass to "see" the variables of the superclass these fields must be declared as protected not private

i will try

[dusk ether]

use getter / setter method

[orchid egret]

sorry im a little stupid, maybe i missed some of the basics somewhere.

uh let me give a full context then because making it protected did not work

i have a class where i had to make all the states object as you can see the Selangor selangor lines

now previously i used Selangor selangor = new Selangor("Selangor", 10, 10, 10) as a parameter

and i used a constructor like this to set the super class values

but now i realized a flaw, every time the class is relaunched, the objects are reinstantiated meaning all the values are reset

so im trying to make it so that the Selangor class objects have a default value like this

but now the super class does not inherit the values from the child class

[dusk ether]

Well do your parents inherit traits from you?

No, they don't. Inheritance is a one way thing.

[orchid egret]

this is the parent class

[orchid egret]

ohhh

how do i make them inherit from a child class

im starting to think this is all just a big design failure from my part

[orchid egret]

ok i might just failed the entire fx app i made for fun lol

aight thanks guys
