Lab 17 Using a linked list with an iterator
Build a class called LinkedListRunner with a main method that instantiates
a LinkedList<String>. Add the following strings to the linked list:
aaa
bbb
ddd
еее
fff
ggg
hhh
ii
Build a ListIterator<String> and use it to walk sequentially through the linked list
using hasNext and next, printing each string that is encountered. When you have printed all the
strings in the list, use the hasPrevious and previous methods to walk backwards through the list.
Along the way, examine each string and remove all the strings that begin with a vowel. When you
arrive at the beginning of the list, use hasNext and next to go forward again, printing out each string
that remains in the linked list.
