Employee
class for use in Figs. 17.10-17.16. (Part 3 of 3.)
Class
ProcessingEmployees
(Figs. 17.10-17.16) is split into several figures so we can
show you the lambda and streams operations with their corresponding outputs.
Figure 17.10 creates an array of
Employee
s (lines 17-24) and gets its
List
view (line 27).
