nested maps

Can someone please help with populating nested maps:

I have 2 maps:
map<id, map<id, string>> map1 = new map<id, map<id, string>>();
map<id, map<id, string>> map2 = new map<id, map<id, string>>();

lets say map1 contains values:
outterid1, innerid1, String1
outterid1, innerid1, String2
outterid1, innerid2, String1
outterid2, innerid1, String1

I need populate map2 using values from map1 as below
outterid1, innerid1, String1;String2
outterid1, innerid2, String1
outterid2, innerid1, String1

Thanks.

Hello, 

here is some idea about add values in  nested map.
 
List<String> SourceList = new List<String>{'TestData1','TestData2'};
List<String> innerKeys = new List<String>{'innerOne','innerTwo'};
List<String> values = new List<String>{'valueOne','valueTwo'};

Map<String,Map<String,String>> NestedMAp = new Map<String,Map<String,String>>();
Map<String,String> interMap
for(Integer i = 0; i< SourceList.size(); i++){

interMap = new Map<String,String>();

for(Integer j = 0; j<innerKeys.size(); j++){
interMap.put(innerKeys[j],values[j]);
}

NestedMAp.put(SourceList[i],interMap);

}
hope this will give some idea. 

Thanks
karthik

Hi Ron08,

Here is a simple process to create nested Map.
// This line creates the map in the proper format
Map<Id,Map<Id,Addendum__c>> addendums = new Map<Id,Map<Id,Addendum__c>>{};

// This for loop goes through each addendum and first places it into a single dimension map.  
// Once that map is created, it is placed into the final multi-dimensional
for(Addendum__c addendum : [SELECT Id,Opportunity__c FROM Addendum__c WHERE Opportunity__c IN :oppBatch])
{
    if(addendums.get(addendum.Opportunity__c) == null)
    {
        addendums.put(addendum.Opportunity__c, new Map<Id, Addendum__c>{addendum.Id => addendum);
    }
    else
    {
        addendums.get(addendum.Opportunity__c).put(addendum.Id, addendum);
    }
}


I hope you find the above solution helpful. If it does, please mark as Best Answer to help others too.
