Getting a list from a config?

Hi. How would I get a list from a config?
Say my config was:

Code:

Amount:
  - 1
  - 2
  - 3
  - 4

How would I get the amounts (1, 2, 3 and 4) and send them to a player?

One more question. How would I create the list
Thanks!

All the get methods and set methods.
As for sending, a simple loop would suffice.

 

Code:java

List<Integer> list = config.getIntegerList("amount");
//get list
 
for(int i : list){
player.sendMessage(list.get(i)); //send it to player
}

is this what you mean?

Okay. I got how to list the string but I do not understand what you mean by creating a loop?

Would

Code:java

List<?> gangs = getConfig().getList("Gangs");
                p.sendMessage(t + "The current Gangs are: " + gangs);

work?

Should really learn basic java before trying to work with a 3rd party api.

 

no. you can't just print a List like that to the player.
you need to loop through the List and print everything the loop finds. for example:

Code:java

List<String> strings = new ArrayList<String>(); //create an empty list for the String object
//set strings
strings.add("I");
strings.add("Like");
strings.add("Pie");
 
//loop through the list and print every string to the player
for(String string : strings){
player.sendMessage(string);
}

this all depends on what your list consists of

My list is:

Code:

Gangs:
  - 1
  - 2
  - 3

EDIT: It wont let me add a list to an ArrayList
This is my code:

Code:java

List<?> gangs = getConfig().getList("Gangs");
                ArrayList<String> gangz = new ArrayList<String>();
                gangz.add(gangs);
                p.sendMessage(t + " The current Gangs are: ");
                for(String g : gangz){   
                    p.sendMessage(g);
                }

 

since it seems like you're only using integers in your list this is what your code would look like:

Code:java

List<Integer> gangs = getConfig().getIntegerList("Gangs");
p.sendMessage(t + "The current Gangs are: " + gangs);
 
for(Integer i : gangs){
player.sendMessage(i.toString());
}

edit: made a mistake in my code sorry x2

And if I was using Strings...? (Sorry, I am noob at configs )

k9rosie
I get this: Type mismatch: cannot convert from element type capture#2-of ? to String
When using:

Code:java

 List<?> gangs = getConfig().getList("Gangs");
p.sendMessage(t + " The current Gangs are: ");
for(String g : gangs){ // <<<<<<<<<<<<<<<<< ERROR ON GANGS
p.sendMessage(g);
}

you would have to change the List parameter to String instead of Integer, change getConfig().getIntegerList() to getConfig.getStringList(), and also change the for loop object as well.

Code:java

List<String> gangs = getConfig().getStringList("Gangs");
p.sendMessage(t + "The current Gangs are: " + gangs);
 
for(String i : gangs){
player.sendMessage(i);
}

Thanks! I am pretty sure I looked for a getStringList
