Tips and Traps¶

1. Notice that Iterable.map returns a List instead of an iterator. Since almost all collections in Kotlin eventually inherit from Iterable, the map method of all collections (including HashMap) in Kotlin returns List.

Create an Empty List¶

sorted¶

If elements in a List implements the Comparable interface, you can call the method sorted to return a sorted List (in nature order).

Note: Pair in Kotin does not implement the Comparable interface!!!
