[Q] Best Way to Handle Commands ?

Hey,

I am pretty new to Java, normally i am working with c++ / c#.
So but the points is i can work with java very well, but I have a question.
I read in the wiki that i should add commands like this:

Code (Text):

getCommand("example").setExecutor(new ExampleCMD());

But right now I preffere to make my own CommandHandler Class and use it like this.
So what I do at the moment is i am just overwriting in the Plugin Main the OnCommand Methode and calling there my CommandHandler:

Code (Text):

    public boolean onCommand(CommandSender sender, Command command, String cmd, String[] args)
    {
        return cmdHandler.handleCommand(sender, command, cmd, args);
    }

thats what i am using now.
But there is also a methode to add a command threw the CommandMap, so whats the best way ? Or it all depents on personal preference ?

Upps, I am really sorry wanted to post this in the plugin help
