storing values in an external file

Or if you don't need the player to be able to modify these values, just compress and export the map with the mappings directly. You can do this like this:

Saving:

File savedirectory = new File(world.getSaveHandler().getSaveDirectoryName().concat("/MySaveInfo.dat"));
savedirectory.createNewFile();
ObjectOutputStream os = new ObjectOutputStream(new GZIPOutputStream(new FileOutputStream(savedirectory)));
os.writeObject(MapContainingPlayerMappedVariables);

Loading:

File savedirectory = new File(world.getSaveHandler().getSaveDirectoryName().concat("/MySaveInfo.dat"));
if(savedirectory.exists()){
ObjectInputStream os = new ObjectInputStream(new GZIPInputStream(new FileInputStream(savedirectory)));
MapContainingPlayerMappedVariables.putAll((Map)os.readObject());
}

 

Remember to encompass file saving/loading in a try catch block in case there are write errors.

I got the save function to work but im having some trouble with the load function, curently I have

package economy.common;

import java.io.*;
import java.util.*;

import org.yaml.snakeyaml.Yaml;

public class Data {

public static String LoadData(String player) throws IOException {
File file = new File("config/EconomyAcounts.yml");

if(!file.exists()) { 
	try {
		file.createNewFile();
	} catch (IOException e) {
		e.printStackTrace();
	}
}

//TODO: Load file

 Yaml yaml = new Yaml();
 List<String> list = (List<String>) yaml.load(document);

 //TODO: find the amount of money the player has

//return amount
}

public static void SaveData(String player, String amount) throws FileNotFoundException {
File file = new File("config/EconomyAcounts.yml");

if(!file.exists()) { 
	try {
		file.createNewFile();
	} catch (IOException e) {
		e.printStackTrace();
	}
}

    Map<String, Object> data = new HashMap<String, Object>();
    data.put(player, amount);
    Yaml yaml = new Yaml();
    String output = yaml.dump(data);
    PrintWriter out = new PrintWriter(file);
    out.println(output);
    out.close();
    
}

}
