Chapter 30.6, Problem 30.6.1CP
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...
