Java: cannot access a protected member of the superclass in the extending subclass

Question

I want some discussions about this, but I could not infer the answer for my case. Still need help.

Here is my code:

package JustRandomPackage;

publi         


        

Answer 1

You aren't creating an instance of the class that extend it, but of the parent class. Check the code below:

public class ATypeNameProgram extends YetAnotherClass{
    public static void main(String[] args) {

        YetAnotherClass bill = new YetAnotherClass();
        System.out.println(bill.variable); // error: YetAnotherClass.variable is not visible

        ATypeNameProgram a = new ATypeNameProgram();
        System.out.println(a.variable); //this will work

    }
}
