Solved YAML - Storing keys w/o values

Helloo.

Is it possible to store 'single worded' data in a YamlConfiguration?
I want to store just a list of names. Like;

Code:

Notch
Unica
Jeb_
Someone
PlayerA
Etcetera

If so, how would I 'get' the data / remove the data?
Or should I use .txt files? I am open for different options

 

@Unica You can. Simply set a List in the "set(path, object)" of your Config and get the List with "getStringList(path)" again

 

@Unica

Just put a tag in front of them like "names:" it's really not that much more difficult.

 

@mythbusterma

I know.
But I was wondering if it was possible to have it plain under eachother due
inserting names outgame (copy - pasting into the config)

 

I'm almost sure this is the closest you will get to what you want(unless you use something else other than yaml):

 

@timtower

I have to admit I didn't really do something with streams in the past.
Any links for tutorials / directions?



@WinX64
I am choosing for that option

Thanks, I've tried some things, and nearly everything works, except the proper removing of Player names.
Like, the player name does get removed, but the .txt file doesn't get 're-ordered'.
I've tried googling some answers, but I didn't get the correct answer I was looking for. Any thoughts?

Example

Code:

playera
playerb
playerc
playerd
playere
notch

If I were to remove player a, the config would be;

Code:

playerb
playerc
playerd
playere
notch

Problem:
I can't use 'list.get(0)' because the first element got removed.
Is there a way to either;
- Get the first String in a .txt file
- Re-order the .txt file so the 'get(2)' becomes 'get(1)' -> 'get(1)' becomes 'get(0)' etc.



Code

Code:

public static void removeFromFile(String name, File mainFolder, String aFilename) throws IOException{
        File file = new File(mainFolder+"/"+aFilename.toLowerCase()+".txt");
        File temp = File.createTempFile(aFilename.toLowerCase(), ".txt", file.getParentFile());
        String charset = "UTF-8";
        String delete = name;
        BufferedReader reader = new BufferedReader(new InputStreamReader(new FileInputStream(file), charset));
        PrintWriter writer = new PrintWriter(new OutputStreamWriter(new FileOutputStream(temp), charset));
        for (String line; (line = reader.readLine()) != null;) {
            line = line.replace(delete, "");
            writer.println(line);
        }
        reader.close();
        writer.close();
        file.delete();
        temp.renameTo(file);
    }

Like,
if I set a value to null in a YamlConfiguration, the entire file just get's moved one up. With
this it will become a blank line.

EDIT:

I currently did

Code:

for(int i = 0; i < list.size(); i++){
       if(list.get(i) != null && !list.get(i).equals("")){
              string= list.get(i);
              break;
       }
}

And that will give me the first actual String of the .txt file.
But I am not sure if that is a efficient way.

SOLVED:

Code:

[/B]list.removeAll(Collections.singleton(""));[B]
