I was thinking to create a class "Pair"
that override equals and hashcode [sic]
That's "hashCode".
and then store here the two keys and then a class that holds an HashMap
with Pair as key and the value class, can be this a solution?
This would be the canonical solution. Make Pair immutable and generic if your keys are of general type, non-generic if you know what the key types are.
