Transferring commands to Command Executor class (Help?)

This is a simple question, how do I begin and transfer commands from my main class to MyCommandExecutor class? I do have multiple commands (as to why I would be using this).

 

Make a new class let it implement CommandExecutor and the add your onCommand. In your main class do getCommand("COMMANDNAME").setExecutor(new Classname(this));

 

I already did that for one, but what about the commands now in the MyCommandExecutor class? How do I separate them? Where do I use the onCommand(...)? How often do I use the onCommand(...)?

 

Only once, but for multiple commands, simply perform multiple if-statements.

 

Code:

    @Override
    public boolean onCommand(CommandSender sender, Command cmd, String commandLabel, String[] args){
       
        Player p = (Player) sender;
       
        if(cmd.getName().equalsIgnoreCase("command")){
            //check for more stuff.
        }
       
        if(cmd.getName().equalsIgnoreCase("another")){
            //do more checks.
        }
           
        return false;
    }
