private int id;
public String name;

public Person(int id, String name) {
this.id = id;
this.name = name;
}

public boolean equals(Object o) {
if (this == o) return true;
if (o == null || getClass() != o.getClass()) return false;
Person person = (Person) o;
return id == person.id && Objects.equals(name, pe
