Adding an Increment Number Key in YML File

Hello there,
I am trying to store information numbered. However I cannot create another number it only overwrites the current key (obvious from code):
ymlfile.set(player + "signs" + "1", "sign text here");

However I want the 1 to ascend by 1 each time it is set. For example if 1 exists then create 2, if 2 exists then create 3......

I was thinking some kind of i++ code. Although I am not that great at that kind of stuff...

SO I was hoping one of you geniuses could figure this out. THANKS!

 

Here a example:

Code:

YamlConfiguration yaml = new YamlConfiguration();
yaml.load(file);
 
int counter = 1;
while (yaml.contains("" + counter))
    counter++;

Ok so it errored. It seems that this is wrong.

Code:

while (plugin.signslogger.contains("" + counter))

its a null pointer exception? Any other way... here is what I am using:

Code:

            SignsPlus plugin;
   
    public SignLog(SignsPlus plugin1){
        this.plugin = plugin1;
    }
 
            int counter = 1;
        while (plugin.signslogger.contains("" + counter))
            counter++;
       
        plugin.signslogger.set(player.getName() + counter + ".Location.X", locationX);

"plugin.signslogger" is a custom yml file I created...

Are there any other ways to solve this question? ? ? ? ? ? ?? ? ? ? THANKS

GeekyCompz is the "signslogger" variable null? Also, the last three lines of code don't seem to be in any method... Was that a copy-and-paste error, or are they just inside the class but not inside a method?

 

chasechocolate that code was just a snippet from the real class/es.

chasechocolate ok so the signslogger is null. DAMN! I just managed to create the YML file and actually have it create it in the plugins folder. Now this is how I actually am using "signslogger":

PHP:

public YamlConfiguration signslogger;
public File signsconfig;
 
public YamlConfiguration loadSignsLog() {
        File signsconfig = new File(getDataFolder(), "Logged-Signs.yml");
        if(!signsconfig.exists()) {
            try {
                getDataFolder().mkdir();
                signsconfig.createNewFile();
                YamlConfiguration signslogger = YamlConfiguration.loadConfiguration(signsconfig);
                signslogger.save(signsconfig);
        }catch(IOException e) {
                e.printStackTrace(); // So they notice
                logger.severe("[SignsPlus] §4Couldn't create the signs logging file.");
            }
        }
        return null;
    }

HOPE it HELPS!
