Explanation of Solution

Purpose of given code:

Purpose of given code is to implements the map aggregate functions for array “values[]” and prints the resultant values.

Explanation:

  • The values “[1, 2, 3, 4, 1]” are printed, because the array is defined with values and the values mapped to “Collectors” class.
  • The variable “values” is mapped into “Set” class, so it print distinct values “[1, 2, 3, 4]” of “list” on screen...
