Find common values in the given maps - Java Quiz Question

Write a program to find common values in the given maps.

Input (Map, Map)	Output (Set)
[A=>Apple, B=>Ball, C=>Cat, G=>Gun, I=>Ice, K=>Kite, M=>Mat], [A=>Ant, B=>Ball, C=>Cat, G=>Gun, I=>Ink, M=>Moon]	[Ball, Cat, Gun]
[A=>Apple, B=>Ball, C=>Cat, G=>Gun, I=>Ice, K=>Kite, M=>Mat], [A=>Apple, B=>Ball, C=>Cat, G=>Gun, I=>Ice, K=>Kite, M=>Mat]	[Apple, Ball, Cat, Gun, Ice, Kite, Mat]
[A=>Apple, B=>Ball, C=>Cat, G=>Gun, I=>Ice, K=>Kite, M=>Mat], [A=>Apple, Z=>Ball, K=>Cat, I=>Ink]	[Apple, Ball, Cat]
[A=>Apple, C=>Cat, I=>Ice, M=>Mat], [B=>Ball, G=>Gun, K=>Kite, N=>Ice]	[Ice]
[A=>Ball, B=>Ant, C=>Gun, G=>Cat, I=>Kite, K=>Ice, M=>Mat], [A=>Gun, B=>Ball, C=>Cat, G=>Gun, I=>Ice, M=>Moon]	[Gun, Ball, Cat, Ice]
