Solved java.lang.ArrayIndexOutOfBoundsException

Hello, I'm sure you have seen forums being posted about this all the time. But I have gone round the so many websites and not found a solution. I have been trying to fix it for the last 2 hours and have had no luck. So I gave up and I'm now doing this, making a forum post. So I am trying to make like a big plugin for a hub and I am doing a /kick command. So I can do /kick (player) and it kicks but I want it so if you do /kick is shows usage. E.g. Usage: /kick (Player) (Reason). Then I get this error

Then I go back and check the code for line 72:
Player t = p.getServer().getPlayer(args[1]);

Code:java

Player t = p.getServer().getPlayer(args[1]);

Here is the whole command syntax:

Code:java

if(cmd.getName().equalsIgnoreCase("kick")) {
 
if(sender.hasPermission(new Permissions().kick)){
 
Player t = p.getServer().getPlayer(args[1]);
 
if(t == null){
 
sender.sendMessage(ChatColor.DARK_GREEN+"[Cryptic Network] "+ChatColor.BLUE+" Usage: "+ChatColor.GOLD+"/kick (User) (Reason)");
 
}}
 
else{
 
sender.sendMessage(ChatColor.DARK_GREEN+"[Cryptic Network]"+ChatColor.DARK_RED+" Not enough permissions... If there is a problem ask a member of staff.");
 
}
 
if(sender.hasPermission(new Permissions().kick)){
 
Player t = p.getServer().getPlayer(args[0]);
 
if(t == null){
 
sender.sendMessage(ChatColor.DARK_GREEN+"[Cryptic Network]"+ChatColor.DARK_RED+" Uh oh... Couldn't find the specified player "+ChatColor.GOLD+args[0]+ChatColor.DARK_RED+"!");
 
return true;}
 
 
 
t.kickPlayer(ChatColor.DARK_RED+"You have been kicked from the server.");
 
sender.sendMessage(ChatColor.DARK_GREEN+"[Cryptic Network] "+ChatColor.BLUE+" Successfully kicked "+ChatColor.GOLD+args[0]+ChatColor.BLUE+" from the server.");
 
}}
 
return false;}}
 
 

Thanks for reading.

 

Ok, sorry. Here is the error:
http://pastebin.com/9710qpPy
Here is the code:
http://pastebin.com/TNG7VzkN

 

the error is you are not checking if there are arguments on the command like
if(args.length == 1){
//that means command has one argument.
}
Also args[1] does not acess the first argument, Java starts countling from 0
Please read a bit more about arrays

Ok, sorry I had some silly mistakes in there I didn't notice. Thanks for helping though .
