How to delete a single value of an List<String> (Config)?

I want to remove only 1 value where it says

Code:

RoflFrankoc:12:DIAMOND_BLOCK:14:false"

I have already tried this:

Code:

  public static void remove(Player p, ItemStack item, int amount){
     List<String> s = new ArrayList<String>();
     s.addAll(config.getStringList("items"));
     int found=0;
     String whole = "";
     for (int i=0;i<s.size();i++){
       String[] a = s.get(i).split(":");
       Player pa = Bukkit.getPlayer(a[0]);
       ItemStack sa = new ItemStack(Material.getMaterial(a[2]));
       int ia = Integer.parseInt(a[3]);
       if (pa == p && item == sa && amount == ia){
         found = i;
         whole = s.get(i);
         break;
       }
     }
     if (found==0){
       return;
     }
     s.remove(found);
     s.remove(whole);
     config.set("items", "");
     config.set("items", s);
   }

 

What does this currently do? What does your expectation of what it should produce look like.

 

@RoflFrankoc
Did you save the config?

 

@FabeGabeMC yes i did
@Zombie_Striker This is gets a string list out of the config and deletes one this is used when a player clicks on that item in an inventory and buys the item

 

@RoflFrankoc

Doesn't look like you did.

 

@RoflFrankoc
Can you print out what "whole" is? Can you print out what the string you're looking for is? Can you tell us if they are EXACTLY the same? I don't know if you can remove an item by index.

 

ArrayList has a remove(int index) method, yes

 

@FabeGabeMC I saved it after i used the function
@Zombie_Striker Im looking for this item:

Code:

RoflFrankoc:12:DIAMOND_BLOCK:14:false

and the whole config is:

Code:

RoflFrankoc:12:DIAMOND_BLOCK:14:false
RoflFrankoc:64:REDSTONE_LAMP:12:false

@Scimiguy does not work though

 

@RoflFrankoc
I suggest you should save it inside the method.

 

@FabeGabeMC Nope still does not work.

 

Then post your new code so we can see why it doesn't work
