Solved Add item to list in Config

Hey,
I want a list in my config, where all players are listed. All of them are saved in the arraylist "freiwillige_spieler". The method getstats() calls my second config file, that should work. Here ist my code so far:

Code:

List<?> users = this.getstats().getList("Nutzer.Liste");
        for(Player p : freiwillige_spieler) {
            if (!users.contains(p.getName())) {
                users.add(p.getName());
            }
        }

What am i doing wrong? Eclipse shows an error in the line i want to add the name to the list. Pls help me!

 

Why not loop through the strings of the list?

Code:

for(String string : getConfig().getStringList(""){
    } 

Then to get the list:

Code:

ArrayList<String> list = new ArrayList<String>();
list = getConfig().getStringList("");

Then to add to it:

Code:

list.remove("");
getConfig().set("", list);

Then to add:

Code:

list.add("");
getConfig().set("", list);

but now that i re-read your question i notice i completly misread it...

To fix what your trying to do:

Code:

List<String> users = this.getstats().getList("Nutzer.Liste");
        for(String s : freiwillige_spieler) {
            if (!users.contains(s)) {
                users.add(s);
            }
        }

Just make sure you save your players as their name, not as the Player data. I forget the reason why, but some guy has it in their signature, just look for that

Code:

ArrayList<String> users = this.getstats().getList("Nutzer.Liste");
        for(String s : freiwillige_spieler) {
            if (!users.contains(s)) {
                users.add(s);
            }
        }

Still not working.

Code:

List<String> users = this.getstats().getList("Nutzer.Liste");
        for(Player p : freiwillige_spieler) {
            if (!users.contains(p.getName())) {
                users.add(p.getName());
            }
        }

Error: "Type mismatch: cannot convert from List<capture#1-of ?> to List<String>"

​

Code:

ArrayList<String> users = this.getstats().getList("Nutzer.Liste");
for(String s : freiwillige_spieler) {
if (!users.contains(s)) {
users.add(s);
}
}

ArrayList<String>

 

Sry, but still same error

Code:

ArrayList<String> users = this.getstats().getList("Nutzer.Liste");
        for(Player p : freiwillige_spieler) {
            if (!users.contains(p.getName())) {
                users.add(p.getName());
            }
        }

Change the type of list that is freiwillige_spieler to ArrayList<String>

 

But the error is in the first line, the thing with the (Player p : freiwillige_spieler) works, but not the getting from config

Here ist the problem:

Code:

ArrayList<String> users = this.getstats().getList("Nutzer.Liste");

 

If you can use Player player : list
then your saving the player data not the player's name
and change this.getstats().getList
to
this.getstats().getStringList

 

a List<?> is not a List<String> and getList returns a List<?>. you may want to switch to getStringList if it is causing you too much trouble.

 

After a little bit of trying arround I got this:

Code:

List<?> users_list = this.getstats().getList("Nutzer.Liste");
     
        ArrayList<String> users = new ArrayList<String>();
        for(Object obj : users_list) {
            String s = (String) obj;
            users.add(s);
        }
     
        for(Player p : freiwillige_spieler) {
            String name = p.getName();
            if(!users.contains(name)) {
                users.add(name);
            }
        }
        List<?> new_users_list = users;
        this.getstats().set("Nutzer.Liste", new_users_list);

Im sure, it would have worked much easier, but now no errors are displayed anymore.

 

Sorry for digging this up everyone, but i felt the need to make sure that the correct way to do this is posted on the solved page.

Code:java

List<String> users_list = this.getstats().getStringList("Nutzer.Liste");
 
ArrayList<String> users = new ArrayList<String>();
for(String str: users_list) {
users.add(str);
}
 
for(Player p : freiwillige_spieler) {
if(!users.contains(p.getName())) {
users.add(p.getName());
}
}
 
this.getstats().set("Nutzer.Liste", users);

If you are getting a List of strings from a config you want to use the getStringList() method which will reurn the type List<String> rather the List<?>. This was said a few times above and i don't know if you missed the posts or ignored them.
Now the last post is the actual solution, and again I'm sorry for digging this up.

*i know there are even more compressed ways of doing this, however this would get the point across
**more compressed way:

Code:java

List<String> players = getConfig().getStringList("players");
 
if(!players.contains(player.getName()))
players.add(player.getName());
else
players.remove(player.getName());
 
getConfig().set("players", players);
