(Config) Need help!

Hello!
I'm currently working at a custom dialogues Plugin, and I want to work with the config.yml to save them. But I always get a NullPointerException at this line:

Code:java

                    int max = fc.getList("dialogues." + s.getLine(2) + ".lines").size();

Here is the whole code:

Code:java

                    FileConfiguration fc = Bukkit.getPluginManager().getPlugin("KnightsOfCosmica").getConfig();
 
                    int i = 0;
                    int max = fc.getList("dialogues." + s.getLine(2) + ".lines").size();
                    List<String> lines = (List<String>) fc.getList("dialogues." + s.getLine(2) + "lines");

s is a sign, and with s.getLine(2) the third line of the sign is gotten.

So, how can I fix this?

 

I would use FileConfiguration fc = this.getConfig();

 

Gabum Can you verify that fc isn't null? Also if you are working with strings, you would be better off using getStringList

 

Also check first if your Sign object isn't null

 

Thx for all the answers, I had personal problems so I did not answer(exams etc), and I now got some work on the problem.

I fixed the first mistake, the path in the config.yml was just in wrong order. But now, if I try to get the list, there is just no object in it. Could you guys tell me the syntax for a String List in the config.yml?

Nevermind, guys. I just found it out:

PHP:

dialogues:
  Chests:
    lines:
    - Dialogue Line 1
    - Dialogue Line 2
