new File() causes NullPointerException

I've got a bug I cannot find out how to fix. It's perfect code, but I cannot get it to work.

Code:

Code:

13    File file = new File(getDataFolder(), "Config.yml");
14    FileConfiguration config = YamlConfiguration.loadConfiguration(file);
15    public void saveDefaults() {
16        if(!file.exists()) {
17            try {
18                file.createNewFile();
19            } catch (IOException e) {
20                getLogger().severe("Could not create Config.yml! " + e);
21            }
22        }
23    }

Here's the error I receive:

Code:

[SEVERE] Error occurred while enabling iMonies v2.1 (Is it up to date?)
java.lang.NullPointerException
    at com.mciseries.iMonies.system.ConfigFile.<init>(ConfigFile.java:13)

 

Try
File file = new File(getDataFolder().getAbsolutePath(), "Config.yml");

Are you declaring a file outside a function?
Can you profile your whole code

 

File file = new File(getDataFolder() + File.separator + "config.yml");

 

This is the whole ConfigFile class:

Code:

package com.mciseries.iMonies.system;
 
import java.io.File;
import java.io.IOException;
 
import org.bukkit.configuration.file.FileConfiguration;
import org.bukkit.configuration.file.YamlConfiguration;
 
import com.mciseries.iMonies.iMonies;
 
public class ConfigFile {
    private iMonies plugin;
    File file = new File(plugin.getDataFolder(), "Config.yml");
    FileConfiguration config = YamlConfiguration.loadConfiguration(file);
    public void saveDefaults() {
        if(!file.exists()) {
            try {
                file.createNewFile();
            } catch (IOException e) {
                plugin.getLogger().severe("Could not create Config.yml! " + e);
            }
        }
        if(file.exists()) {
            this.setDouble("Options.DefaultBalance", 100.00);
            this.setString("Options.SingularName", "Dollar");
            this.setString("Options.PluralName", "Dollars");
            this.setString("Messages.Prefix", "iMonies");
            this.setString("Messages.Money", "Balance: $<balance>");
            this.setString("Messages.Set", "Changed balance to $<balance>");
            this.setString("Messages.Create", "Created account named <name>");
            this.setString("Messages.Pay", "Payed <name> $<amount>");
            this.setString("Messages.Empty", "Deleted all accounts");
            this.setString("Messages.Remove", "Deleted <name>''s account");
            this.setString("Messages.Errors.NoPermission", "No permission");
            this.setString("Messages.Errors.NotEnoughMoney", "Not enough money");
            this.setString("Messages.Errors.NegativeAmount", "Can''t pay amounts less than a cent");
            this.setString("Messages.Errors.NotEnoughArgs", "Not enough arguments");
            this.setString("Messages.Errors.TooManyArgs", "Too many arguments");
        }
    }
    public void setDouble(String path, double value) {
        config.set(path, value);
    }
    public void setString(String path, String value) {
        config.set(path, value);
    }
    public void setInt(String path, int value) {
        config.set(path, value);
    }
    public void setBoolean(String path, boolean value) {
        config.set(path, value);
    }
}

I'm calling saveDefaults() with:

Code:

new ConfigFile().saveDefaults();

You never set your plugin variable. You should add

public ConfigFile(iMonies instance){
plugin = instance;
}

 

Oh, so basically plugin is a null variable? Huh. I'll try it now, thanks.

Wow, failed spelling of paid.
