1 out of 4 Commands are working, though very similar...

First off here is the code:
http://www.showmycode.com/?4124f41886eeeff2f1bec509e6c95c75

Now, when I ran it on my test server with one of my admins. Only the /incap <player> part would work, not /uncap <player> or just /incap and /uncap, which should do the effect to me.

Any help would be useful. Thanks in advance.

1. You use arg[0] before checking whether args.length == 1
2. You have to move the "uncap" part out of the "incap" part. The command can't be uncap and incap simultaneously.

Code:java

    public boolean onCommand(CommandSender sender, Command cmd, String commandLabel, String args[])
    {
        Player player = (Player)sender;
        String Player = player.getName();
        if(commandLabel.equalsIgnoreCase("incap"))
        {
            if(args.length == 0)
            {
                player.addPotionEffect(new PotionEffect(PotionEffectType.CONFUSION, 9999, 0));
                player.addPotionEffect(new PotionEffect(PotionEffectType.BLINDNESS, 9999, 0));
                player.addPotionEffect(new PotionEffect(PotionEffectType.SLOW, 9999, 0));
                player.sendMessage((new StringBuilder()).append(ChatColor.RED).append("You were incapacitated").toString());
            }
            if(args.length == 1)
            {
        Player targetPlayer = player.getServer().getPlayer(args[0]);
        String tPlayer = targetPlayer.getName();
                targetPlayer.addPotionEffect(new PotionEffect(PotionEffectType.CONFUSION, 9999, 0));
                targetPlayer.addPotionEffect(new PotionEffect(PotionEffectType.BLINDNESS, 9999, 0));
                targetPlayer.addPotionEffect(new PotionEffect(PotionEffectType.SLOW, 9999, 0));
                player.sendMessage((new StringBuilder()).append(ChatColor.GRAY).append((new StringBuilder("You incapacitated ")).append(tPlayer).toString()).toString());
                targetPlayer.sendMessage((new StringBuilder()).append(ChatColor.RED).append((new StringBuilder("You were incapacitated by ")).append(Player).toString()).toString());
            }
 
        }
        if(commandLabel.equalsIgnoreCase("uncap"))
            {
                if(args.length == 0)
                {

                    player.addPotionEffect(new PotionEffect(PotionEffectType.BLINDNESS, 0, 0), true);
                    player.addPotionEffect(new PotionEffect(PotionEffectType.SLOW, 0, 0), true);
                    player.sendMessage((new StringBuilder()).append(ChatColor.RED).append("You are no longer incapacitated!").toString());
                }
                if(args.length == 1)
                {
        Player targetPlayer = player.getServer().getPlayer(args[0]);
        String tPlayer = targetPlayer.getName();
                    targetPlayer.addPotionEffect(new PotionEffect(PotionEffectType.CONFUSION, 0, 0), true);

                    player.sendMessage((new StringBuilder()).append(ChatColor.GRAY).append((new StringBuilder("You un-incapacitated ")).append(tPlayer).toString()).toString());
                    targetPlayer.sendMessage((new StringBuilder()).append(ChatColor.RED).append((new StringBuilder(String.valueOf(Player))).append(" un-incapacitated you!").toString()).toString());
                }
            }
