The simple way would be to use Greenfoot.ask(String) to get the name and the UserInfo class to save/recall the name. You could put the asking in a for loop to limit attempts to be of proper length and either truncate or use a default name if all attempts fail to be of use.

        String nm = Greenfoot.ask("Enter name (no more than 10 characcters long)");
        if (nm == null || "".equals(nm) || nm.length() > 10) continue;

Create player at end of started method in World subclass with: new Player(name) and add it to the world.
