Solved For loop problem

Heey developers,
when i run this loop it returns 0.

Code:

for(int i=0;i<core.getConfig().getKeys(false).size();i++) {
                        player.sendMessage("" + i);
                       
                        String iString = Integer.toString(i);
                       
                        if(core.getConfig().getConfigurationSection(iString).getString("Name").equalsIgnoreCase(event.getLine(2).toString())) {
                            player.sendMessage("4");
                            player.sendMessage(Core.prefix + ChatColor.DARK_GREEN + "Start " + ChatColor.GREEN + "sign created!");
                            event.setLine(1, ChatColor.YELLOW + "Start");
                            event.setLine(2, ChatColor.YELLOW + core.getConfig().getConfigurationSection(iString).getString("Name"));
                        } else {
                            event.getBlock().setType(Material.AIR);
                            player.playSound(player.getLocation(), Sound.STEP_STONE, 10, 0);
                            player.sendMessage(Core.prefix + ChatColor.RED + "This map doesn't exist!");
                        }
                    }

 

@CheesyFreezy What do you mean it 'returns' 0? Do you mean it sends the player the message '0'? Because a for loop doesn't return anything.

 

@CheesyFreezy Are the sections in your YAML file labeled with numbers? I think your logic may be a bit off.

 

@nverdier it returns 0 when i do player.sendMessage("" + i);
@Skionz the configurationsections are all strings. But i'm getting the size of the amount of configurationsectionsections. So it's an integer

 

@CheesyFreezy Your attempting to get values using keys such as 0, 1, 2, 3, 4, 5, etc. Based on your code this is what it should look like

Code:

0:
    Name: 'Stuff'
1:
    Name: 'Stuff'
2:
    Name: 'Stuff'
3:
    Name: 'stuff'

I'm not sure if thats a logic error.

 

@Skionz
that's exactly what i want.... but what's the problem? why is it not working?

 

@CheesyFreezy Iterate over the keys instead of using an int to get them? Would be easier.

 

@Burnett
how?

 

@CheesyFreezy Well what does getKeys(false) return?

 

@Burnett
getKeys(false) returns [1,2]
getKeys(false).size() returns 2

 

@Skionz Just a little note, as far I know you should use '0' instead of just 0 when you use just a number in the yml (or at least that's what bukkit seems to do)

 

It doesn't matter, it will always be a string key. That's simply what happens when bukkit stores the key as a string and saves it.

 

@1Rogue Ahh, alright, thanks for the clarification

 

@CheesyFreezy No, getKeys() returns a Set<String> containing your keys. You can then use:

Code:java

for(String s : core.getConfig().getKeys(false))

 

@Burnett
Okay i'll try that

@Burnett,
it's returning 1, eventhough i'm having 2 configurationsections

EDIT: It's working now, i had to reload the server, now it s working. Thanks for the help!
