的Java IndexArrayOutOfBounds問題

所以我有一些代碼在執行時給出了一個錯誤...的Java IndexArrayOutOfBounds問題

 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; 
     }

這是我的錯誤日誌。
