Args in a command!

Hello, I am trying to make a bungeecord plugin with the command /L, so if you did /L it would send you to the Lobby server, and if you did /L skyblock it would send you to the skyblock server, I got the /L to work but I can get the args to work any help please! Error I get in console will be down the under the code.

Code (Java):

package best.ashton.bungee.Commands;

import net.md_5.bungee.api.ChatColor;
import net.md_5.bungee.api.CommandSender;
import net.md_5.bungee.api.ProxyServer;
import net.md_5.bungee.api.chat.TextComponent;
import net.md_5.bungee.api.connection.ProxiedPlayer;
import net.md_5.bungee.api.plugin.Command;

import java.lang.reflect.Proxy;

public class ServerCommand extends Command {
    public ServerCommand() {
        super("l", "dev.lobby");
    }

    @Override
    public void execute(CommandSender sender, String[] args) {
        if (args.length == 0) {
            ProxiedPlayer p = (ProxiedPlayer) sender;
            p.connect(ProxyServer.getInstance().getServerInfo("Lobby"));
            return;
        } else if (args.length == 1) {
            if (args[1].equalsIgnoreCase("Skyblock")) {
                ProxiedPlayer p = (ProxiedPlayer) sender;
                p.connect(ProxyServer.getInstance().getServerInfo("Skyblock"));
            }
        }
    }
}
