Hi
I have a Person Object that has members: firstname, lastname and DOB
public class Person {
private String firstName;
private String lastName;
private Date dob;
/** Construct a Person given the first name, last name, and birth
date. */
public Person(String firstName, String lastName, Date dob) {
if (firstName == null || lastName == null || dob == null) {
throw new IllegalArgumentException();
}
this.firstName = firstName;
this.lastName = lastName;
this.dob = dob;
}
}
The application uses Person objects in Collections, placing them into
Collection implementations and querying if a Person is in a Collection
using the Collection.contains() method. The application also uses
Person objects as keys in Maps to associate other objects with Persons
and to efficiently look up those objects based on Person.
How can I modify this Person Object so that the lookup is efficient?
Any help??
