I get this Map from a collection and collection might have 1000 or more Maps
so I first iterate over this collection retrieve the map and then iterate
over this map so creating a new Map for each iteration is this a good design
?
Thanks & Regards

Ok first of all you cannot modify a HashMap while you are iterating it.
But your problem has a solution.
Iterate the map and store into another map the key-value pair (with the
key turned to uppercase)
Then clear the original map and then call "putAll"
