Get value by key inside a Map<String, Map<String, Double>> JSP

Question

I have a

Map<String, Map<String, Double>>

and I'd like to get the Double value by some given keys. I've found that it can be done using "c:foreach" but I want to find some values, I don't want to iterate all of them. It would be something like:

myMap['myKey']['myAnotherKey']

How can I do this?

Answer 1

if you know the keys

Double val = myMap.get(myKey).get(myAnotherkey);

Answer 2

Try this

<c:out value="${myMap['myKey']['myAnotherKey']}"/>
