为什么“ printperson（）”方法不调用子类的私有方法？

Question

public class Test {
  public static void main(String[] args) {
     new Person().printPerson();
     new Student().printPerson();
  }
}

class Student extends Person {
  private String getInfo() {
     return "Student";
  }
}

class Person {
  private String getInfo() {
    return "Person";
  }
  public void printPerson() {
    System.out.println(getInfo());
  }
}

The answer is

Person
Person

But when I change both the private access-specifiers to public, the result is

Person
Student

Why? I can't understand.

Answer 1

Private methods are not visible in subclasses and therefore can't be overriden. So it always invokes a method from parent class.
