How would I convert IniPreferences to a Map in Java?

I currently have

public static Map<String, String> configMap;

Ini ini = new Ini(configIni);
    java.util.prefs.Preferences prefs = new IniPreferences(ini);
configMap = new HashMap<>();
    configMap.put("Version", prefs.node("Settings").get("Version", null));

However this would require me to insert the key for anything added to the ini making it a pain to maintain.

The prefs.node will always be settings however preferably they would be combined into configMap.

How would I automate this?
