Making a list of strings.

I currently have a file set out like this for each player:

Code:

Perks:
    Example1: true
    Example2: false
    Example3: true
    Example4: true

How do i get each true "example" and add it to a string list, so i can send a messsage to a player along the lines of..

"Currently activated perks: Example1, Example3, Example4"

 

Code:

        List<String> activatedPerks = new ArrayList<String>();
        for (String keyString : getConfig().getConfigurationSection("Perks").getKeys(false)){
            if (getConfig().getBoolean("Perks." + keyString) == true){
                activatedPerks.add(keyString);
            }
        }

 

Thanks, What does '(false)' do?

 

false means it's a shallow search, it only finds the root level keys of the "Perks" section:

Set<String> org.bukkit.configuration.ConfigurationSection.getKeys ( boolean deep )
Gets a set containing all keys in this section.
If deep is set to true, then this will contain all the keys within any child ConfigurationSections (and their children, etc). These will be in a valid path notation for you to use.
If deep is set to false, then this will contain only the keys of any direct children, and not their own children.

 

Thanks for the help
