java overriding static fields

Question

public class A {
       public String s="A";
       public static int i=1;
   }
public class B extends A {
      public String s="B";
      public static int i=2;
public static void main(String [] args) {
              A a= new B();
              B b= new B();
              System.out.print(a.s+a.i);
              System.out.print(b.s+b.i);
}
}

Why the output is "A1B2" instead of "A1B1"? Doesn't fields can't be overridden, and also static fields can't?

You're not overriding anything -- you're **hiding** fields. – Hovercraft Full Of Eels Aug 15 '16 at 04:04 — Hovercraft Full Of Eels, Aug 15 '16 at 04:04
Does "hiding" can be done with the static field? – avivlevi Aug 15 '16 at 04:09 — avivlevi, Aug 15 '16 at 04:09
What is the difference between hiding and overriding? – avivlevi Aug 15 '16 at 04:19 — avivlevi, Aug 15 '16 at 04:19

It seems that you're confused with the concept of Overriding.

in Java, as far as class variables are concerned, you do not override them, you hide them.

Overriding is for instance methods. Hiding is for instance variables.

Both Hiding and Overriding are different.

+1 just because this answer is totally correct and probably only was voted -1 by the question author, because he didn't understand or want to hear the answer... – Michael K Nov 24 '17 at 09:37
