Solved Loading a custom config file from plugin and saving it

I know, I know, there are a huge amount of threads like this, but trust me, I've been looking through all of them carefully and I always end up getting a blank "lang.yml" file.
My actual code:

Code:

public class Main extends JavaPlugin implements Listener{
  
    File langFile = new File(this.getDataFolder() + "lang.yml"); //Or "/lang.yml", tried both
    FileConfiguration lang = YamlConfiguration.loadConfiguration(langFile);
[...]
@Override
    public void onEnable() {
        try {
            lang.save(langFile);
        } catch (IOException e) {
            e.printStackTrace();
        }

Any thoughts on why it doesn't work? I have a lang.yml file next to my plugin.yml one.

 

I don't see any code that copies the contents of your file to the config

 

EDIT: I don't think what I wrote works anyways.

removed...

 

What about this: (still doesn't work)

Code:

public class Main extends JavaPlugin implements Listener{
  
    File langFile = new File(this.getDataFolder() + "/lang.yml");
    FileConfiguration lang = YamlConfiguration.loadConfiguration(langFile);
  
    private static ItemStack wrench = null;
    private static int msl = 0;
    HashMap<UUID, Location[]> pos = new HashMap<UUID, Location[]>();
    HashMap<UUID, ArrayList<HashMap<Location, HashMap<Material, Byte>>>> undo = new HashMap<UUID, ArrayList<HashMap<Location, HashMap<Material, Byte>>>>();
  
    //Thing
    private void copy(InputStream in, File file) {
        try {
            OutputStream out = new FileOutputStream(file);
            byte[] buf = new byte[1024];
            int len;
            while((len=in.read(buf))>0){
                out.write(buf,0,len);
            }
            out.close();
            in.close();
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
    //Not a thing
  
    @Override
    public void onEnable() {
        if(!langFile.exists()){
            langFile.getParentFile().mkdirs();
            copy(getResource("lang.yml"), langFile);
        }
        try {
            lang.save(langFile);
        } catch (IOException e) {
            e.printStackTrace();
        }

 

@DoggyCode™ Does this also work for , example:

/load town
and now it loads a config called town, in which you can do what you want.
the town is a string in your config path

 

@Ganga I don't think I know exactly what you mean by that. But yea, I guess.

 

Apparently saveResource("lang.yml", true); does the work.
Thanks for the help, still!

 

@Crack498
