• Practice reading and writing a text file using the Files class from the java.nio package.

Given the GroceryListDriver class again, modify the program to use the Files class from the java.nio package to read and write a text file.

Reuse the last lab to modify the methods you already wrote to use the new classes we just learned about.

To implement the reading and writing of a text file, consider the following instructions and tips:

• Modify the GroceryListDriver class.
  • Rewrite the method to write to a text file.
    • Use the writeString() method to write to a text file.
    • Each item in the list should be on its own new line.
    • Refer back to the Java NIO lesson.
  • Rewrite the method to read a text file line-by-line.
    • Use either the readString() method or the readAllLines() method to read from the text file.
    • Return a String to print out to the console the list of groceries.
    • Refer back to the Java NIO lesson.
• When running the GroceryListDriver class, pass in a file named grocery-list.txt.
• Remove the @Disabled annotation from the unit tests and ensure that the tests pass successfully. Refactor as needed.
