collections - list.map can take a string in scala -

is str somehow implicitly converted str.charat, map function works?

val str = "abcdefghij" println(list.range(0, 10).map(str)); 

since str seq of character, .map on str call given index.

eg.

scala> list.range(0, 10).map(str) res0: list[char] = list(a, b, c, d, e, f, g, h, i, j)  // or .apply scala> list.range(0, 10).map(str.apply) res7: list[char] = list(a, b, c, d, e, f, g, h, i, j) 

and str(index) gives value index, see stringops#apply(index: int): char

scala> "my string"(4) res5: char = t 

other array , seq example,

scala> val array = array(1, 2, 3, 4, 5) array: array[int] = array(1, 2, 3, 4, 5)  scala> list.range(0, 4).map(array) res1: list[int] = list(1, 2, 3, 4)  scala> val list = seq(10, 20, 30, 40, 50) list: seq[int] = list(10, 20, 30, 40, 50)  scala> list.range(0, 4).map(list) res3: list[int] = list(10, 20, 30, 40)
