Chapter 19, Problem 16PE

Program Plan Intro

Group the word by first letter

Program plan:

• Include the required header files
• Define the class “Word”
  • Define the main method
    • Declare the string variable with the file name as a value
    • Create an object for “Map” class
    • In the “try” block, create an object and pass the filename as an argument.
      • Read all the words in the file
      • Iterate the loop until it reaches the end of the file
        • Add the word into the “wordList” variable
      • Get the strings from the file and group the words by first letter, and then find the average of each letter in the file using “collect” and “Collectors.groupingBy” methods.
    • Display the result.
