Please forgive my code and only focus on the question here :

we know that private field is not inherited and when i am creating object at line #2 the object is being created for Person and then when i set the fatherName , inside the setFatherName() how is **this ** “which is object of person” has the visibility to set Test class private fatherName ?

abstract class Test {
private String fatherName ;

public void setFatherName(String fatherName){
    System.out.println(this.getClass().getSimpleName());
    this.fatherName=fatherName;
}
public String getFatherName(){
   return  fatherName;
}

}

public class Person extends Test{

public static void main(String[] args) {
    Test person = new Person(); // #2
    person.setFatherName("Jimmy");
    System.out.println("father name is : " +person.getFatherName());

}

}

Output :
Person
father name is : Jimmy

I understand the context that i am indirectly doing it with a setter but how does “this” keyword work here in abstract class since object is Person . Did my best to post the question accurately.
