your driver should read the data from a text file where each line in

the input file represents one item and the line includes the following values separated by

tab: $(1)$ a number $(1,2,$ or $3)$ to specify whether the line represents an ItemA, ItemB, or

Item object respectively, $(2)$ string value, $(3)$ integer value, and $(4)$ an integer value for

ItemA lines or boolean value for ItemB lines. Assume the input file is formatted correctly

and you do not have to check for lines that are not in the given format. This is an example

input file:

$1$ aaa $1020$

$2$ bbb $20$ true

$3$ ccc $39$

$2$ aaa $10$ false

$3$ aaa $10$

$1$ ddd $4050$

$2-$ Create an input file of at least $20$ lines with at least $5$ lines for each item type

$($Item$/$ItemA$/$ItemB$).$ Include some duplicate lines to test that the add method does not

add duplicate items.

$3-$ Write code to ask the user for the path of the data file, read the file name, open the file, read

the file line by line, and upload the data to an SortedSet.

$4-$ Print the list. Make sure the items are in sorted order and there are no duplicates.

$5-$ Include at least two test cases for each one of the following methods: indexOf, remove,

grab, and categorySet. Make sure to print appropriate messages in the output so

that it is easy to interpret your test cases
