Solved Split string in sign ?

Hello,

I'm trying to make a sign shop plugin (yes it already exists) but I'm blocking on this :
My string won't split or something but it doesn't work

Code:

        if (b.getType() == Material.SIGN || b.getType() == Material.WALL_SIGN) {
            Sign sign = (Sign) b.getState();
            if (sign.getLine(0).equalsIgnoreCase("[Shop]")) {
                sign.setLine(0, "§2[§aShop§2]");
                sign.update();
            }
            if (sign.getLine(0).equals("§2[§aShop§2]")) {
                String bloc = sign.getLine(2).toString().toUpperCase();
                String[] Splitted = sign.getLine(1).split("\\:");
               
               
                player.sendMessage("Oui");
                if (Splitted[0] == "B") {
                    player.sendMessage("t");
                    if (isInt(Splitted[1])) {
                        player.sendMessage("tt");
                        if (!sign.getLine(2).isEmpty()) {
                            player.sendMessage("ttt");
                            if (!isInt(bloc)) {
                                player.sendMessage("tttt");
                                if(economy.getBalance(player.getName()) >= Integer.parseInt(Splitted[1]) ) {
                                    player.sendMessage("ttttt");
                                    economy.withdrawPlayer(player.getName(), Integer.parseInt(Splitted[1]));
                                    player.getInventory().addItem(new ItemStack(Material.matchMaterial(bloc)));
                                    player.sendMessage(prefix + "You bought a §6" + sign.getLine(2).toString() + " §7!");
                                } else {
                                    player.sendMessage(prefix + "You don't have enough money !");
                                }
                            }
                        } else {
                            player.sendMessage("té");
                            player.sendMessage(prefix + "This shop sells nothing !");;

So it only says "Oui" as I wrote here. My code doesn't find "B". I tried to make it in a command and it works perfectly.

Please help!
