Write a program that reads in a text file and then computes and prints a table of letter frequencies. For example, if the file is the text of "A Tale of Two Cities", found in the file atdata/tales.txt, the program will print:

Please enter the pathname or URL of the book file: data/tales.txt
Letter frequencies in data/tales.txt
a        47,065
b         8,142
c        13,223
d        27,484
e        72,878
f        13,152
g        12,121
h        38,355
i        39,779
j           622
k         4,633
l        21,516
m        14,924
n        41,308
o        45,115
p         9,452
q           655
r        35,950
s        36,771
t        52,393
u        16,217
v         5,065
w        13,835
x           666
y        11,849
z           213

I am confused as to how to represent my code in this nice table above.  Any hints? Here is my code so for:

package assignment3solutions;

import java.util.ArrayList;

import stdlib.In;
import stdlib.StdIn;
import stdlib.StdOut;

public class LetterFrequencies {
        
        public static void main(String[] args){
                
                StdOut.println("Please enter the pathname or URL of the book file: ");
                String textSource = StdIn.readLine();
                
                final In in = new In(textSource);
                if(!in.exists()){
                        StdOut.print("Unable to open file " + textSource);
                System.exit(1);
                }
                
                String[] bookOfWords = bookFile.split("\\s+");
                
                ArrayListwordFrequencies = new ArrayList();
                
                for(String word: bookOfWords){
                        wordFrequencies.add()
