Your task is to go through that String and count the occurrence of the letters and then print out the final tally of each lettere, how many 'a's how many 'bs, etc.) You can test your program with any text file, easiest if you put the text file in the same folder as your code. For example, if you have a file, book.txt, then you can simply type in book.txt when prompted by the program for the filename if the file is in the same folder as your program file. Submit a program and run the test cases to see the expected output format

Explanation-

In, this in order, to store the tally of each letter we can take an array of 26 length.

Array indexed from 0-25 represents the count of each character i.e

for example, arr[0] represents count of letter 'a',

arr[1] represents count of letter 'b',

'' '' ''

  arr[25] represents count of letter 'z'

CODE-

So, in the above given program,

1) after line 12, firstly declare an array of length 25

int[] arr=new int[26]; //declare new array of length 26 (for 26 characters a-z)

Arrays.fill(arr,0); //fill all the character counts to 0 initially

2) Now, on line 28, we will loop through each character of the line fetched and if the line[i] is a character, we will increment the corresponding position of that letter in arr.

for(int i=0;i<line.length();i++){

int ascii=line[i];   

arr[ascii-97]++;

}

3) Now, at line 40, print the counts of all the characters. i.e

for(int i=0;i<26;i++){

System.out.println("Count of "+ alphabet[i] + "is:" + arr[i]);

}
