Saving a <String, Integer> HashMap

Hello, I need some help saving a <String, Integer> HashMap. I'm making an API and I need a way to save this hashmap to a file or config. Any help is appreciated!

Code:java

package me.bdking00.c;
 
import java.util.HashMap;
 
import org.bukkit.entity.Player;
import org.bukkit.plugin.java.JavaPlugin;
 
public class Main extends JavaPlugin {
 
    public static HashMap<String, Integer> coins = new HashMap<>();
 
    public void onEnable() {
        getConfig().options().copyDefaults(true);
        saveConfig();
    }
 
    public void onDisable() {
        saveConfig();
    }
 
    public void addCoins(Player p, int i) {
        Main.coins.put(p.getName(), Main.coins.get(p.getName()) + i);
    }
 
}

Not the best of the things to do, but you could send all the Strings to a list in your config, and then put a path for every string with the int.

 

Yeah, the thing is, I don't know how to actually save the HashMap to the config

 

try this:

Code:java

HashMap<String, Integer> test = new HashMap<String, Integer>();
 
public void getMap(){
        for(String s : this.getConfig().getStringList("StringList")){
            Integer value = this.getConfig().getInt(s);
            test.put(s, value);
        }
    }
 
    public void saveMap(HashMap<String, Integer> map){
        List<String> l = new ArrayList<String>();
        for(Entry<String, Integer> e : map.entrySet()){
            String key = e.getKey();
            Integer value = e.getValue();
            if(!l.contains(key)){
                l.add(key);
            }
            this.getConfig().set(key, value);
        }
        this.getConfig().set("StringList", l);
        this.saveConfig();
    }

Bukkits configuration api already got a inbuilt way to save hashmaps

If you want to retrieve the hashmap after
