saving config as a list

Hey guys! I am making a plugin that includes world listing,
I am using

Code (Text):

Bukkit.getServer().getWorlds().stream().map(World::getName).collect(Collectors.joining(", "));
 

to list the worlds, but I am wondering how do I add a list to config for example

Code (Text):

BlacklistedWorlds
-eg1
-eg2
-eg3
 

I already have the concept of how to blacklist

Code (Text):

String worlds = Bukkit.getServer().getWorlds().stream().map(World::getName).collect(Collectors.joining(", "));
            worlds= worlds.replace(" " + blacklistedworld+ ",", "");
 

how would I beable to save the config as a list and add/remove from the list. and how would I find how much blacklisted worlds there is so I can make a for loop to replace the worlds in the string

 

looked on docs couldn't find setStringList or anything similar.

 

That is getStringList, not setStringList
