Solved Get values from keys in config

I'm trying to make a plugin in which you can sign up for jobs(e.g. farmer, miner etc.).
But I have a really annoying bug. I have a forloop that goes through all the keys in the config section:

Code:

public void getItems(){
       
        for(String key : core.getConfig().getConfigurationSection("JobItems").getKeys(false)){
           
            //TODO fix item bug
           
            int i = Integer.parseInt(key);
           
            items.add(new ItemStack(i, 1));
           
        }
       
    }

But now I have a NBE. I think I know what the problem is, but don't know how to fix it(problem is possibly that "getKeys()" returns the name of the key, and not the value?).

Config:

Code:

JobItems:

    Timberman: 258

    Miner: 257

    Farmer: 292

If anyone can help me, feel free to reply

 

@pipo3090
core.getConfig().getConfigurationSection("JobItems")

^^ This should be set in a variable above and then just call .getInt(key) on the object set, settings above will make sure you dont call it twice when you have to call it once again in the loop.

 

Can you give an example? I don't really know what you mean.

 

Code:

ConfigurationSection section = section
for key in section do
      get an int from section with the key key.
end

 

I tried, but I get an error: Can only iterate over an array or an instance

EDIT: here's my code that I used

Code:

ConfigurationSection cs = core.getConfig().getConfigurationSection("JobItems");
       
        for(String key : cs/*error is here*/){
           
           
            //items.add(new ItemStack(is, 1));
           
        }

 

Made an edit with the code that I used.

 

@timtower Works! Thank you both
