我有以下代码

import java.util.HashMap;
import java.util.Map;
import java.util.Objects;

public class Person {
  private String name;
  private long birthTime;

  @Override
  public int hashCode() {
    return Objects.hash(name, birthTime);
  }

  @Override
  public boolean equals(Object obj) {
    if (this == obj) {
      return true;
    }
    if (!(obj instanceof Person)) {
      return false;
    }
    Person other = (Person) obj;
    return Objects.equals(name, other.name)
        && birthTime == other.birthTime;
  }

  public String getName() {
    return name;
  }

  public void setName(String name) {
    this.name = name;
  }

  public long getBirthTime() …
