How can i access Class A variable in m1() method directly?

Question

class A {
    int i = 10;
}

class B extends A {
    int i = 20;
}

public class C extends B{
    int i = 30;

    public static void main(String[] args) {
        C c = new C();
        c.m1();
    }

    public void m1() {
        System.out.println(i);       // 30
        System.out.println(super.i); // 20
    }
}

I have a class A , which contains a default variable. I created a child class B which extends class A and one more child class C which extends class B .

I want to access class A variable in child class C m1() method. Is there any direct way to access it?

Answer 1

change this line

System.out.println(super.i); // 20

to

System.out.println(((A)this).i);

Answer 2

To complicate your life try this:

public void m1() {
    System.out.println(this.i);
    C c = new C();
    Class<? extends Object> cls = c.getClass().getSuperclass().getSuperclass();
    Field[] fields = cls.getDeclaredFields();
    for ( Field field : fields )
    {
        String in = field.getName();
        int iv = field.get((Object)c);
        System.out.println(iv);
    }
}
