Getting a string list from config without a list

I do not really know how to phrase this question. But, how do you get a list of strings from within a sub group in a config file.
For example I have this comfig:

Code:

foo1:
    something: blah
    someotherthing: blah2
foo2:
    something: blah
    somethingthing: blah2

How do I get foo1 and foo2?

 

Code:java

for(String table : getConfig().getKeys(false)) {
            String blah1 = getConfig().getString(table + ".blah1");
            String blah2 = getConfig().getString(table + ".blah2");
        }

 

The method getConfig().getKeys(false) in type JavaPlugin returns a Collection of String containing each key at the first level of the config.yml
You can use it at any level. For instance :

Code:

Smthg1:
  value1: s
  value2: ss
Smthg2:
  value3: sss
  value4: ssss

Using

Code:java

Set<String> lvl1 = Plugin.getConfig().getKeys(false);
for(String s : lvl1) {
System.out.println(s);
}
 

Will return : "Smthg1" and "Smthg2"

While this code :

Code:java

Set<String> lvl2 = Plugin.getConfig().getConfigurationSection("Smthg1").getKeys(false);
for(String s : lvl2) {
System.out.println(s);
}

Will return : "Smthg1.value1" and "Smthg1.value2"

Note : Passing the argument true while using getKeys() will return all the keys of the configuration section, no matter their level. (For our first example "Smthg1", "Smthg1.value1" and "Smthg1.value2" would have been printed.

Hope it helped !
