Solved What's wrong with args?

I have a problem with args that I don't know why it is not working?

PHP:

public boolean onCommand(CommandSender sender, Command command, String commandLabel, String[] args) {//command
        if(sender instanceof Player) {
            Player p = (Player) sender;
            /**//*HERE*//**/String avenger = args[0].toLowerCase();/**//*HERE*//**/
           
            if(command.getName().equalsIgnoreCase("Assemble")) {
                if(avenger == "ironman") {
                    if(p.hasPermission("avenger.ironMan") || p.isOp()) {
                        if(avengerType == 6) {
                            p.sendMessage("test");
                        } else {
                            p.sendMessage(ChatColor.GREEN + alreadyMessage);
                        }//avenger type isn't 6
                    } else {
                        p.sendMessage(ChatColor.DARK_PURPLE + noPermissionMessage);
                    }//permissions
                }//ironman
               
                if(avenger == "thor") {
                    if(p.hasPermission("avenger.thor") || p.isOp()) {
                        if(avengerType == 6) {
                            p.sendMessage("test");
                        } else {
                            p.sendMessage(ChatColor.GREEN + alreadyMessage);
                        }//avenger type isn't 6
                    } else {
                        p.sendMessage(ChatColor.DARK_PURPLE + noPermissionMessage);
                    }//permissions
                }//thor
               
                if(avenger == "hulk") {
                    if(p.hasPermission("avenger.hulk") || p.isOp()) {
                        if(avengerType == 6) {
                            p.sendMessage("test");
                        } else {
                            p.sendMessage(ChatColor.GREEN + alreadyMessage);
                        }//avenger type isn't 6
                    } else {
                        p.sendMessage(ChatColor.DARK_PURPLE + noPermissionMessage);
                    }//permissions
                }//hulk
               
                if(avenger == "captainamerica") {
                    if(p.hasPermission("avenger.captainAmerica") || p.isOp()) {
                        if(avengerType == 6) {
                            p.sendMessage("test");
                        } else {
                            p.sendMessage(ChatColor.GREEN + alreadyMessage);
                        }//avenger type isn't 6
                    } else {
                        p.sendMessage(ChatColor.DARK_PURPLE + noPermissionMessage);
                    }//permissions
                }//captain
               
                if(avenger == "blackwidow") {
                    if(p.hasPermission("avenger.blackWidow") || p.isOp()) {
                        if(avengerType == 6) {
                            p.sendMessage("test");
                        } else {
                            p.sendMessage(ChatColor.GREEN + alreadyMessage);
                        }//avenger type isn't 6
                    } else {
                        p.sendMessage(ChatColor.DARK_PURPLE + noPermissionMessage);
                    }//permissions
                }//widow
               
                if(avenger == "hawkeye") {
                    if(p.hasPermission("avenger.hawkEye") || p.isOp()) {
                        if(avengerType == 6) {
                            p.sendMessage("test");
                        } else {
                            p.sendMessage(ChatColor.GREEN + alreadyMessage);
                        }//avenger type isn't 6
                    } else {
                        p.sendMessage(ChatColor.DARK_PURPLE + noPermissionMessage);
                    }//permissions
                }//hawk
               
                if(avenger != "ironman" &&
                    avenger != "thor" &&
                    avenger != "hulk" &&
                    avenger != "captainamerica" &&
                    avenger != "blackwidow" &&
                    avenger != "hawkeye") {
                   
                    p.sendMessage(ChatColor.GOLD + "That is not an Avenger!");
                   
                    if(!p.hasPermission("avenger.hawkEye") || !p.isOp()) {
                        p.sendMessage(ChatColor.RED + "AAAANNNNDDDD You don't have permission!");
                    }//no permission, and fail
                }//fail at avenger
            }//getCommand
        }//if sender is a player
        return(false);
    }//command method

When I type /Assemble ironman, i get "That is not an avenger!". Same with all of the other heroes. What is wrong with my args?

 

.equalsIgnoreCase() instead of == to compare string

Also check to make sure args.length==1

 

No need. If the args do no equal an avenger, than it will tell you. Ty.

 

Yes need, type in /assemble with nothing after it.

 

Already figured that out during tests. What I thought would happen was it would just set the string to nothing, and move on, but apparently not. Length of the args isn't working, but I can solve it.

 

You're using it wrong.

You must check it otherwise you'll get an exception because the index does not exist.

 

Already fixed, I did args[0].length() instead of args.length. Errors gone, and there is nothing to worry about. Ty for everybody who helped.
