Solved YamlConfiguration returns always 0

Code:java

public void save(Player p) {
        PlayerDataFile = new File("plugins/myplugin/"+ p.getName().toLowerCase() +".yml");
        PlayerDataConfig = new YamlConfiguration();
        if(!PlayerDataFile.exists())
        {
            try
            {
                PlayerDataConfig.save(PlayerDataFile);
                PlayerDataConfig.createSection("xp");
                PlayerDataConfig.createSection("xplevel");
                PlayerDataConfig.createSection("hunger");
                PlayerDataConfig.createSection("health");
                PlayerDataConfig.createSection("inventory");
                PlayerDataConfig.createSection("armor");
                PlayerDataConfig.save(PlayerDataFile);
            }
            catch (IOException e)
            {
            }
        }
        try
        {
            PlayerDataConfig.save(PlayerDataFile);
            PlayerDataConfig.set("xp", p.getExp());
            PlayerDataConfig.set("xplevel", p.getExpToLevel());
            PlayerDataConfig.set("hunger", p.getFoodLevel());
            PlayerDataConfig.set("health", ((CraftPlayer)p).getHealth());
            PlayerDataConfig.set("inventory", p.getInventory().getContents());
            PlayerDataConfig.set("armor", p.getInventory().getArmorContents());
            PlayerDataConfig.save(PlayerDataFile);
        }
        catch (IOException e)
        {
        }
    }

Code:java

public void restore(Player p) {
        log.info("0");
        PlayerDataFile = new File("plugins/myplugin/"+ p.getName().toLowerCase() +".yml");
        PlayerDataConfig = new YamlConfiguration();
        if(!PlayerDataFile.exists()){
            log.info("file not exist");
            return;
        }
        p.setExp((float)PlayerDataConfig.getDouble("xp"));
        p.setLevel(PlayerDataConfig.getInt("xplevel"));
        p.setFoodLevel(PlayerDataConfig.getInt("hunger"));
        p.setHealth(PlayerDataConfig.getDouble("health"));
 
        List<ItemStack> Inv = (List<ItemStack>) PlayerDataConfig.getList("inventory");
        List<ItemStack> Arm = (List<ItemStack>) PlayerDataConfig.getList("armor");
 
        p.getInventory().setContents((ItemStack[]) Inv.toArray());
        p.getInventory().setArmorContents((ItemStack[]) Arm.toArray());
 
    }

playername.yml

Code:

xp: 0.0
xplevel: 17
hunger: 20
health: 20.0
[...]

PlayerDataConfig.getDouble("xp"), PlayerDataConfig.getInt("xplevel"), PlayerDataConfig.getInt("hunger"), PlayerDataConfig.getDouble("health") -> return all the value 0

.. PlayerDataConfig.load(PlayerDataFile) ..
