I have the following code:

```
public boolean onCommand(CommandSender sender, Command cmd, String commandLabel, String[] args) {
    // Do stuff
}

```

I want to be able to do this:

```
public boolean onCommand(CommandSender sender, Command cmd, String commandLabel, String[] args) {
    someMethod(sameParameters);
}

```

How do I do this? Can you provide an example?
