First, create a map. The default Map in the first line is immutable, and the second line is mutable.

Val map1 = Map ("bajie"-> 20, "wukong"-> "80", "wujing"-> 100)

Val map2 = scala.collection.mutable.Map ("bajie"-> 20, "wukong"-> "80", "wujing"-> 100)

Val map3 = new scala.collection.mutable.HashMap [String, Int]

Second, Map operation, find map1 ("bajie"), map1 ("bajie") = 30, and map1-= "bajie", map1 + = ("shifu"-> 1000)

Third, the iteration of map is 100 times simpler than that of java.
