Saving hashmaps

Hey guys,
I'm trying to save a hashmap but I can't figure it out.
I tried to edit this code : www.youtube.com/watch?v=IMA2dXJR-7E so it would work the way I wanted but I couldn't figure it out.

So here's my code for creating the kills and hashmap

Code:

     public HashMap<String, Integer> kills = new HashMap<String, Integer>(); //before onload

Than this event

Code:

    @EventHandler(priority = EventPriority.HIGHEST)
    public void onPlayerDeath(PlayerDeathEvent event) {
        if (event.getEntity().getKiller() instanceof Player) {
            Player killer = event.getEntity().getKiller();
            if (!kills.containsKey(killer.getName()))
                kills.put(killer.getName(), 0);
            kills.put(killer.getName(), kills.get(killer.getName()) + 1);
        }
    }

Which works fine btw!
But I need to save it to a config file.
Can someone help me with this ?

Thanks in advance,
CB

Code:

    public void serializeHashMap(HashMap<String, Integer> map) {
        for(Entry<String, Integer> entry : map.entrySet()) {
            getConfig().set(entry.getKey(), entry.getValue());
        }
        saveConfig();
    }

 

Do you maybe also know to use onLoad the code to let it split and things?

Thanks a lot already.

And is it possible to make more configs so also for death config? how should I do that.

Thanks in advance,
CB

But I can safe it in the same config? Or?
3ptO Thanks a lot already bro!
You're a hero , going to add and test it now

Do I need to import the Entry from Java.util.map ?

How do I let these 2 voids run, like one onLoad and one on Disable, I tried serializeKills();
but than it gives an error (in the code)

3ptO Hehe Okay thanks bro!
Problem :
OnLoad :
killMap cannot be resolved to a variable

            if (!kills.containsKey(killer.getName()))
                kills.put(killer.getName(), 0);
            kills.put(killer.getName(), kills.get(killer.getName()) + 1);
        }
    }
   
   
//kills thingeydone

Now it seems like I'm using 2 different hashmaps, kills and killMap ???

No error now
Just tested it:

Results:
Saving is fine, config.yml :
Kills:
- Priceuser_:1
- 99IRock:0
But...,
OnEnable, deserializeKills(kills) isn't working.
My kills are again 0
Is it maybe a problem with this :
onCommand /kills

Code:

if(commandlabel.equalsIgnoreCase(("kills"))){
if(args.length == 0){
if(kills.get(sender.getName()) == null){
            kills.put(sender.getName(), 0);
}
sender.sendMessage("Kills : " + kills.get(sender.getName()));
}

Because when I remove that about kills == null and set to 0, the problem is that the whole kills counting won't work anymore. (null + 1 = still 0 xD) but I might have an idea for that in the kill code. but about the deserializeKills no idea

I tried something but I couldn't figure out, I tried changing kills.put to MCInfinite.kills.put (MCInfinite is the main class)
But didnt work... And I still don't understand why that deserialize doesn't works.

3ptO I just don't know whats wrong with the code, I checked it and it looks fine but mhm ?

 

CraftBang If you want to save your HashMap in your config, you can do it in a simple way by using SuperEasyConfig

 

I also need help with this! 3ptO
EDIT: How can I refresh the scorboard (like every minute)?

 

I don't really understand why 3ptO 's post are deleted or why he removed them ( I don't know if he did)

But the code I use :

Code:

 public void serializeKills(HashMap<String, Integer> kills) {
     List<String> list = new ArrayList<>();
  
     for (Entry<String, Integer> entry : kills.entrySet()) {
         list.add(entry.getKey() + ":" + entry.getValue());
     }
     getConfig().set("Kills", list);
     saveConfig();
 }
 
 public void deserializeKills(HashMap<String, Integer> kills) {
     List<String> list = getConfig().getStringList("Kills");
  
     for (String string : list) {
         String one = string.split(":")[0];
         String two = string.split(":")[1];
  
         kills.put(one, Integer.getInteger(two));
     }
 }

Serialize DOES work fine, but Deserialize NOT.
Still don't understand why not, I don't see any problems..
I don't like to bumb but can someone please help me?
IS something wrong with the splitting ?
