public class Person {
  private String name, comment;
  private int age;
  public Person(String n, int a, String c) {
   name = n; age = a; comment = c;
  }
  public boolean equals(Object o) {
   if (! (o instanceof Person)) return false;
   Person p = (Person)o;
   return age == p.age && name.equals(p.name);
  }
}

What is the appropriate definition of the hashCode method in class Person?

return super.hashCode();
return name.hashCode() + age * 7;
return name.hashCode() + comment.hashCode() / 2;
return name.hashCode() + comment.hashCode() / 2 - age * 3;
