Question

In my code i have a

Map<String,Map<String,customObject>>

I am not sure how to iterate over this map and get the values from it.
What i am trying to do here is get the enclosing Map by passing in the key to the external Map.
When i get the enclosing map i need to iterate over it and get key and value from it.
Can you please let me know how i can do this as i am kind of stuck here.
Any example or code of a similar type can be of a great help to understand it better.

Thanks

To iterate over hashmap entries…

for (Map.Entry<String, Map<String, Object>> ent : hashmap.entrySet())
{
    //ent.getKey();   is the key [String]
    //ent.getValue(); is the value [Map<String, Object>]
}

Now work out from there, it’s basically the same.
