I need to simplify the letter count and add scaling to the word bar char a i have the array set to 12 but it needs to read a file and then produce the amount of frequency and length in that particular file
import java.io.*;
import java.util.*;

class WordCount
{
public static void main(String[] args) throws IOException
{
FileReader file = new FileReader("new.txt");
BufferedReader MyFile = new BufferedReader(file);

StringTokenizer TokenizeMe= new StringTokenizer("");
int NumberOfTokens = 0;
int NumberOfWords = 0;
char barchart = '#';
char[] letters = { 'A', 'B', 'C', 'D', 'E', 'F', 'G', 'H', 'I', 'J','K', 'L', 'M', 'N', 'O', 'P', 'Q', 'R', 'S', 'T', 'U', 'V', 'W', 'X', 'Y', 'Z'};


int frequency [] = new int [12];
// frequency [] stores number of words of length

Create a method called findElementIndex, which takes an integer and an integer array as input parameters, and returns the smallest index where that value appears. If the value is not in the array, the method should return -1.

Example:
value: 3 theArray:{10, 3, 6, 3, 8, 10} ==> 1
value:10 theArray:{11, 3, 6, 7, 9, 60} ==> -1

Create a method called countOdds which takes an integer array as a parameter, and returns the number of odd entries in the array.


Examples:
theArray:{10, 3, 6, 3, 8, 10} ==> 2
theArray:{11, 3, 6, 7, 9, 60} ==> 4
