1. Download the books.csv file from Canvas. Open this file with notepad to see the format, dont worry if this file defaulted to open in excel.

2. Download the Book.java file from Canvas. Import this file into your java project.

3. Create a class called BookStoreManagementDriver. This class should contain the methods listed below.

a. main method, which should do the tasks listed below.

i. Create an array of object references of type Book. You may default the size to 5.

ii. Ask the user for keyboard input for the input file name and output file name. Then create the Scanner object for the input file and the PrintWriter object for the output file.

iii. Then ask the user for keyboard input whether to sort the by high to low, or low to high cost.

iv. Read the file from step 1 in line by line. For each line split it using the StringTokenizer. Then use each set of tokens to create a Book object in the array of Books.

Note: Each book should have a unique location inside the array.

v. Use the compareTo method to sort the books based on the users choice (described above). (Hint: use logic similar to selection sort)

vi. Use the equals method to record which books are duplicates. (Hint: use a boolean array to help determine which are duplicates)

vii. Print the ordered and refined book store data into the output file.

viii. Print to the terminal window after each task has been completed. So that the user can see what has been completed.
