Question

代码片段：

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)
  }
}

对于Person类，请问哪个选项中的hashCode()方法是最合适的？

A. return super.hashCode()

B. return name.hashCode() + age * 7

C. return name.hashCode() + comment.hashCode() / 2

D. return name.hashCode() + comment.hashCode() / 2 - age * 3
