Initialisation de variable a condition

Bonjour,


je voudrais creer une classe qui permet dee faire un login et logout depuis un serveur, l'adresse ip de celui-la est definie d'une facon statique au debut de la fonction , comme suit:

private static String loginURL = "http://192.168.1.5/android_login_api/"

je voudrais savoir si c'est possible d'initialiser cet url depondament d'une condition(d'une facon dynamique). par exemple(c'est juste pour clarifier ce que je veux faire):

if(this.isConnectedToServer("192.168.1.5", 500)) {
    private static String loginURL = "http://192.168.1.5/android_login_api/";
}

if(this.isConnectedToServer("192.168.1.9", 500)) {
    private static String loginURL = "http://192.168.1.9/android_login_api/";
}

j'ai pensé a passer l'url en parametre dans tous les fonctions de ma classe mais je crois que c'est moche. je fais utiliser ca comme dernier recours.
toute proposition est le bienvenue ,je n'ais pas de contraintes. voici ma classe :

public class UserFunctions {

private JSONParser jsonParser;

private static String loginURL = "http://192.168.1.5/android_login_api/";
private static String mplayerURL = "http://192.168.1.5/android_mplayer_api/";
private static String registerURL = "http://192.168.1.5/android_login_api/";

private static String login_tag = "login";
private static String register_tag = "register";
private static String delete_tag = "delete";
private static String update_tag = "update";
private static String music_tag = "music";
private static String getusers_tag = "getusers";


// constructor
public UserFunctions(){
    jsonParser = new JSONParser();
}
