Solved Removing value from config list

Code:

@EventHandler
    public void blockBreak(BlockBreakEvent event){
        if(event.getBlock().getType() == Material.CHEST){
            event.getPlayer().sendMessage("BROKEN CHEST");
            List<String> locationList = plugin.getConfig().getStringList("chest-data.locations");
            Location location = event.getBlock().getLocation();
            String locationString = location.getBlockX() + "," + location.getBlockY() + "," + location.getBlockZ();
            event.getPlayer().sendMessage("PRE LOCATIONLIST DATA");
            if(locationList.contains(locationString)){
                event.getPlayer().sendMessage(locationList.toString());
                event.getPlayer().sendMessage(locationString);
                event.getPlayer().sendMessage(locationList.toString());
                locationList.remove(locationString);
                event.getPlayer().sendMessage("LOCATIONSTRING REMOVED");
            }
          
          
        }

Yeah, When I run this code, you can see in the game, it even says "LOCATIONSTRING REMOVED" but as you can also see it is not removed.

EDIT: BEFORE IT WAS JUST 7 LINES, NOW IT IS 8 LINES.
A VALUE IS ADDED TO THE HASHMAP WHEN A CHEST IS PLACED.

 

@MasterDoctor It's because you're sending the message of the strings before it's actually removed, so it's still inside of the list. You need to put the line of code

Code:

 locationList.remove(locationString);

before

Code:

 
event.getPlayer().sendMessage(locationList.toString());
                event.getPlayer().sendMessage(locationString);
                event.getPlayer().sendMessage(locationList.toString());

 

I didn't even see that! lol But I check the config and it still isn't there
BRAIN DERP: I forgot to

Code:

plugin.getConfig().set("chest-data.locations", locationList);
plugin.saveConfig();
