Hi,
I have a class :
public class AuthenticationManager {

    private static final Logger _logger = LoggerFactory.getTrimmer(AuthenticationManager.class.getSimpleName());
    private final List<Listener> _listeners = new ArrayList<Listener>();
    private boolean _verificationInProgress = false;
    private final CallStateReceiver callStateReceiver = new CallStateReceiver();


I was wondering is it a good practice to have the line :
    private final CallStateReceiver callStateReceiver = new CallStateReceiver();

or should one chnage it to private final CallStateReceiver callStateReceiver ; and get it set from outside ?

What way can we define this ?

Thanks
