In Scala, how to check if a Map contains all entries from another Map?

Question

Total newb question. Say I have 2 maps

val map1 = Map(\"ram\"->\"2gb\", \"size\"->\"15\", \"color\"->\"red\", \"fruit\"->\"strawberry\")
val map2 =          


        

Answer 1

You can convert a Map to a Set and then apply the subsetOf method.

val map1 = Map("ram"->"2gb", "size"->"15", "color"->"red", "fruit"->"strawberry")
val map2 = Map("ram"->"2gb", "size"->"15", "color"->"red")

map2.toSet subsetOf map1.toSet // res0: Boolean = true
