Command Arguments || checking length

Hi, i need to check the length of command arguments and return a message with the correct usage if they get it wrong.

Commands:
/verify set [String]
/verify check

/answer [String]

I'm pretty sure i do not need to provide my code, any help would be greatly appreciated, thanks.

 

Code:

@Override
public boolean onCommand(CommandSender sender, Command cmd, String commandLabel, String[] args) {
    if(cmd.getName().equalsIgnoreCase("verify")) {
        if(args.length<1) {
            sender.sendMessage("To few arguments");
            return false;
        }
        if(args[0].equalsIgnoreCase("set")) {
            if(args.length<2) {
                sender.sendMessage("To few arguments");
                return false;
            }
            // Do Whatever
        }
        if(args[0].equalsIgnoreCase("check")) {
            if(args.length>1) {
                sender.sendMessage("To many arguments");
                return false;
            }
            // Do Whatever
        }
    }
    if(cmd.getName().equalsIgnoreCase("answer")) {
        if(args.length<2) {
            sender.sendMessage("To few arguments");
            return false;
        }
        // Do Whatever
    }
}
