Removing a string from a string list

I'm trying to remove a specific string from all the string lists in a config file but every way i have tried it does not work from some reason that i cannot wrap my head around. Here is how my config looks

Code:

  Group1:
    Members:
    - signal23
    Friends:
    - Group2 | NO_PVP
  Group2:
    Members:
    - alphab76
    Friends:
    - Group1 | NO_PVP

What i'm trying to do is when a group gets deleted it will remove any friend groups it may have, so if i delete Group2, Group1 would have - Group2 | NO_PVP removed from it as that group no longer exists but i can't get it to be removed. it also has to be able to remove - Group2 | NO_PVP from every Friends: path if it is there here is my method that i have now that i can't seem to get working

Code:java

public void removeGroupsFriends(String removedGroupName) {
 
        if(Core.getInstance().cm.getGroupsConfig().getConfigurationSection("Groups.") != null) {
 
            for(String group : Core.getInstance().cm.getGroupsConfig().getConfigurationSection("Groups.").getKeys(false)) {
 
                List<String> values = Core.getInstance().cm.getGroupsConfig().getStringList("Groups." + removedGroupName + ".Friends");
 
                for(String members : values) {
 
                    String name = members.split(" | ")[0];
 
                    values.remove(name);
 
                    Core.getInstance().cm.getGroupsConfig().set("Groups." + removedGroupName + ".Friends",  " ");
 
                    Core.getInstance().cm.getGroupsConfig().set("Groups." + removedGroupName + ".Friends", values);
 
                    Core.getInstance().cm.saveGroupsConfig();
                }
            }
        }
    }

 

Anyone know why?

 

It appears that if you removed Group1 , your latter code is looking IN Groups.Group1.Friends to see if there are any instances of Group1 to remove ... you dont appear to be checking the OTHER groups friends list.

 

Why are you implementing a pseudo-list when you can already use List<String> directly from a FileConfiguration?

I couldn't get it working that way how would you do it?

 

Code:

yourList:
- this
- is
- an
- example
- potato

Code:java

String rem = "example";
List<String> lis = /*config*/.getStringList("yourList");
if (!lis.isEmpty()) { lis.remove(rem); }
/*config*/.set("yourList", lis);
/*config*/.save();

Code:

yourList:
- this
- is
- an
- potato
