def map[B](f: A => B): F[B]Copy As we can see, the map() function takes a function that transforms a value of type A into a value of type B. Let’s explore a few example usages from Scala’s standard library types, such as List and Option: // on List val numbers = List...
String value = mulmap.getFirst("firstKey"); And finally, addAll(K key, V… newValues) adds multiple values to the current list of values for the supplied key: mulmap.addAll("firstKey", "secondValue", "thirdValue"); 6. Summary In this article, we saw the differences between Map an...

First, we create two maps map1 and map2 using the Map constructor and provide key-value pairs. Here are the steps we need to follow to determine the difference between the two maps: Retrieve the set of keys from map2 using the keySet method ...
When a non-bool x is converted to a bool, non-zero becomes true and zero becomes false, as if you had written x != 0. When bool is converted to non-bool, true becomes 1 and false becomes 0.The type "BOOL" is a Windows type, and it's just a typedef for int. As such, it ...
