Static Binding of Private Methods

Consider the following code segment.

class A {
  private void secret() {
    System.out.println("A secret");
  }
  public void reveal() {
    secret();
  }
}

class B extends A {
  private void secret() {
    System.out.println("B secret");
  }
}

public class Main {
  public static void main(String[] args) {
    A obj = new B();
    obj.reveal();
  }
}

What is printed as a result of executing the code?
