Task #4– Now read the file that you just created

This is a simple program that simply reads the disk-based file, using the Scanner Class, that you created in task #3.

The user input is the name of the file that you wish to read.

For your output:

Display the contents of the named file that has the heading “The Alphabet”

Display a “File read completed “message to the user

Pseudocode:

Prompt the user for a file name

Append the file extension to the filename

Open the file

Iterate through each line of the file and display the resultant line on the console

Close the file

Display a “Completed reading the file” message to the user
