"adding" to list on config?

Ok so my hashmap:

Code:

    public static HashMap<String, String> hashmap = new HashMap<String, String>();

Gets put into config:

Code:

                hashmap.put(player.getName(), player.getName());
                getConfig().set("Minez", hashmap.get(player.getName()));
                saveConfig();

But when multiple players get put in, the config just replaces, how do i make it go to the next line?

 

Well, there are many ways to do this. The easyist?

hashmap.put(player.getName(), player.getName());
getConfig().set("Minez.playersnameHere", hashmap.get(player.getName()));
saveConfig();

Then to retrieve it, you could just do hashmap.put(bob7l, getconfig.getString("minez.bob7l")

 

Thanks!
