create an array of Employee objects.
create an ArrayList of Employee objects from that array.
use an enhanced for loop to print all employees as shown in the sample output.
create a TreeMap that uses Strings for keys and Employees as values.
this TreeMap should map Employee ID numbers to their associated Employees.
process the ArrayList to add elements to this map.
print all employees in ID # order as shown, but do so using the TreeMap's forEach method and a lambda expression
