Indeed, a nested for

 

 

Map<String,Map<String,String>>initStringStringMap = new Map<String,Map<String,String>>{'one' => new Map<String, String>{'a'=>'b', 'c'=> 'd'}, 'two' =>new Map<String, String> {'e'=>'f', 'g'=> 'h'} };
for(String outerKey : initStringStringMap.keySet())
for(String innerKey : initStringStringMap.get(outerKey).keySet())
System.debug(' ----------------------------------------------------------------  >>>>>>>>>>>>>>>' + initStringStringMap.get(outerKey).get(innerKey));

Map<String,Map<String,String>> stringStringMap = new Map<String,Map<String,String>>{};
.
Map<String,Map<String,String>>initStringStringMap = new Map<String,Map<String,String>>{'one' => new Map<String, String>{'a'=>'b', 'c'=> 'd'}, 'two' =>new Map<String, String> {'e'=>'f', 'g'=> 'h'} };

Just before i mark this as solution, do you think create a class to hold the data will be good choice ? since we can directly get the value ?

You can do, if it affords you reusability. If not, just use it as a data structure.
