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 ?
Surely it is not a good design, but that is up to you. You asked a thing and I answered. Maybe you have to turn your question inside-out: Why are you putting keys as non-uppercase strings, when you need it? Maybe you could implement a java.util.Map in a case-insensitive way, where the key must be a string, and it does not matter what its keys case is. But again this is up to you, I cannot do your homework :-P
