Set interface contains no duplicated elements, In the example below the soccer player "Lionel Messi" appears twice, fix the SoccerPlayer class in order that Set interface works properly

import java.util.HashSet;
import java.util.Set;

public class CollectionTest {

public static void main(String[] args) {
Set<SoccerPlayer> soccerPlayers = new HashSet<>();
soccerPlayers.add(new SoccerPlayer("Lionel", "Messi"));
soccerPlayers.add(new SoccerPlayer("Cristiano", "Ronaldo"));
soccerPlayers.add(new SoccerPlayer("Lionel", "Messi"));

print(soccerPlayers);
}

private static void print(Set<SoccerPlayer> soccerPlayers) {
soccerPlayers.forEach(soccerPlayer -> System.out.println(soccerPlayer));
}
}

class SoccerPlayer {
private final String name;
private final String lastName;

public SoccerPlayer(String name, String lastName) {
this.name = name;
this.lastName = lastName;
}

@Override
public String toString() {
return "Soccer Player = {" +
"name=" + name + "," +
"lastName=" + lastName+
"}";
}
}
