File understanding problem.

I want to create file, which would hold information like: integers and names, file would be called star.yml, I watched a lot tutorials, but most of tutorials in resources are really bad and I'm lost now. I don't get, which one should I use: Configuration +- File or YamlConfiguration from http://jd.bukkit.org/rb/apidocs/index.html?index-all.html . Even http://wiki.bukkit.org/Configuration_API_Reference isn't helpful for me :/.

 

If you want to use a file seperate from config.yml, you can copy and paste the code under the header "Mirroring the JavaPlugin implementation " from the second link.

 

Code:

FileConfiguration star = null;
File starFile = null;

And what's next? What line should be in onEnable to load it? Because I see only reload/save.

I get error if I write:

Code:

try {
                star.load(starFile);
            } catch (Exception e) {
                e.printStackTrace();
            }
        }

Code:
