Java IndexArrayOutOfBounds问题

Question

所以我有一些代码在执行时会出错......

        if (!(sender.hasPermission("nexodus.an"))) {
            player.sendMessage(ChatColor.BLACK + "[" + ChatColor.DARK_PURPLE + "NexodusMC" + ChatColor.BLACK + "]" + ChatColor.GREEN + " You can not do this command!");
            return true;
        } else if (args.length == 0) {
            player.sendMessage(ChatColor.BLACK + "[" + ChatColor.DARK_PURPLE + "NexodusMC" + ChatColor.BLACK + "]" + ChatColor.GREEN + " You must specify a predetermined message to broadcast!");
            player.sendMessage(ChatColor.BLACK + "[" + ChatColor.DARK_PURPLE + "NexodusMC" + ChatColor.BLACK + "]" + ChatColor.GREEN + " 1: Server Restarting");
            player.sendMessage(ChatColor.BLACK + "[" + ChatColor.DARK_PURPLE + "NexodusMC" + ChatColor.BLACK + "]" + ChatColor.GREEN + " 2: Login servers are currently down!");
            player.sendMessage(ChatColor.BLACK + "[" + ChatColor.DARK_PURPLE + "NexodusMC" + ChatColor.BLACK + "]" + ChatColor.GREEN + " 3: Reloading for GameModes");
            return true;
        } else if (args.length > 1) {
            if (args[0].equalsIgnoreCase("1")) {
                Bukkit.broadcastMessage(ChatColor.BLACK + "[" + ChatColor.DARK_PURPLE + "NexodusMC" + ChatColor.BLACK + "]" + ChatColor.GREEN + " NexodusMC will be restarting in 5 seconds.");
            } else if (args[0].equalsIgnoreCase("2")) { 
                Bukkit.broadcastMessage(ChatColor.BLACK + "[" + ChatColor.DARK_PURPLE + "NexodusMC" + ChatColor.BLACK + "]" + ChatColor.GREEN + " Login servers are currently down. Logging off my prevent you from getting back on, sorry!");
//Line above is line 53 ||
            } else if (args[0].equalsIgnoreCase("3")) {
                Bukkit.broadcastMessage(ChatColor.BLACK + "[" + ChatColor.DARK_PURPLE + "NexodusMC" + ChatColor.BLACK + "]" + ChatColor.GREEN + " Server reload due to adding/removing/editing gamemodes!");
            }
            return true;
        }

这是我的错误日志。
