I need to merge both maps and if a key has different values in both maps, those values should be added for the particular key from different maps. The merged map should have unique keys and its values along with added values for same key.

Hey. I have two maps : Map<String, int> m1 = new HashMap<>() and Map<String, int> m2 = new HashMap<>();
and these have values respectively as m1 : { a=20, b=40, c=40} and m2: { a=19, x= 30, y=80}
And I want to go through each map and its values (they have "a" a common and I want both values of "a" summed up) and print both common and unique values  and store  to further use them. How do I do that?
