Command not working properly

Every time i type in: /xpcomm it gives me a internal error! (Works when i type /xpcomm reload)
Why?

Code:

    public boolean onCommand(CommandSender sender, Command cmd, String commandLabel, String[] args){
        if(cmd.getName().equalsIgnoreCase("xpcomm")){
                
            if(args[0].contentEquals("reload")) {
                
                String name = sender.getName();
                sender.sendMessage(name);
                return true;
                
            } else {
                
                sender.sendMessage(ChatColor.WHITE + "Usage: " + ChatColor.DARK_RED + "/xpc <command>");
                return true; 
                
            }
         }
        return false;
   
    }

 

Try

Code:

    public boolean onCommand(CommandSender sender, Command cmd, String commandLabel, String[] args) {
        if (cmd.getName().equalsIgnoreCase("xpcomm")) {
            sender.sendMessage(ChatColor.WHITE + "Usage: " + ChatColor.DARK_RED + "this is sent if you type it with nothing afterwards *i think*");
            if (args[0].equalsIgnoreCase("reload")) {
                String name = sender.getName();
                sender.sendMessage(name);
                return true;
            }
            else {
                sender.sendMessage(ChatColor.WHITE + "Usage: " + ChatColor.DARK_RED + "/xpc <command>");
                return true;
            }
        }
        return false;
    }

And tell me what happens and tbh i have no idea what the contentEquals stuff did, so i changed that to equalsIgnoreCase

 

Nope, the exact same thing happend, only thing is that the "this is sent if you type it with nothing afterwards *i think*"
message came up whatever i did.

 

Before you check that args[0] is equal to something, check that the args.length() > 0. If not, then return false or send them the proper use of the command because they didn't supply any arguments.

 

This worked, thank you!

 

Google is your friend here (and so is stackoverflow, very handy site): http://stackoverflow.com/questions/...quals-and-stringcontentequals-methods-in-java

Basically, contentEquals() can be used to compare a String with objects of other string-like types. equals()/equalsIgnoreCase() can only be used to compare with other Strings. In the code above, there's no particular need to use contentEquals().

 

Uhm, that was me jsut trying random stuff to see if it worked..
