Solved Saving HashMaps

Hello, I've been recently trying to work with hashmaps, and I can't seem to be able to figure out how to save a hashmap that has a key as a String (Name) and the values in in an String List. If anyone would let me know how to do so, I'd greatly appreciate it.

Code:

Code:java

if (!conf.contains("groups")
                || !conf.isConfigurationSection("groups"))
            conf.createSection("groups");
        ConfigurationSection sec = conf.getConfigurationSection("groups");
 
        Map<String, String[]> groups = new HashMap<String, String[]>();
 
        for (String key : sec.getKeys(false)) {
            if (sec.isString(key))
                groups.put(key, sec.getString(key));
        }

EDIT:
I think I figured it out, if I'm mistake could someone please let me know.

Code:java

if(!conf.contains("records") || !conf.isConfigurationSection("records"))
            conf.createSection("records");
        ConfigurationSection sec = conf.getConfigurationSection("records");
 
        Map<String, List<String>> records = new HashMap<String, List<String>>();
 
        for(String key : sec.getKeys(false)){    
            ArrayList<String> list = new ArrayList<String>();
            if(sec.isString(key))
                list.add(key);
            records.put(key, list);
        }
