Count total occurrence of each character in a given file code example

Example 1: How do you count characters in a string array in Java?

package practical5;

import java.util.Arrays;

public class Part1_9 {

public static void main(String[] args) {

    // declaring and populating array
    String quoteArray[] = { "\"Continuous", "effort", "not", "strength",
            "nor", "intelligence", "is", "the", "key", "to", "unlocking",
            "our", "potential.\"\n" };

    // for loop to print full array
    for (int counter = 0; counter < quoteArray.length; counter++) {
        System.out.print(quoteArray[counter] + " ");
    }// end of for loop

    // Printing array using Enhanced for/ for each loop (Different way to
    // print array)
    for (String element : quoteArray) {
        System.out.print(element + " ");
    }// end of enhanced for

    // line break
    System.out.println();

    // printing number of words in array
    System.out.println("Number of words in array: " + quoteArray.length);

    **// printing total number of letters in array**
    for (int counter = 0; counter < quoteArray.length; counter++) {
        String letters = new String(quoteArray[counter]);
    }

    // printing the smallest word

    // printing the biggest word

}// end of main

}// end of class

Example 2: c program to the count the number of times each character appears

#include <stdio.h>
int main() {
    char str[1000], ch;
    int count = 0;

    printf("Enter a string: ");
    fgets(str, sizeof(str), stdin);

    printf("Enter a character to find its frequency: ");
    scanf("%c", &ch);

    for (int i = 0; str[i] != '\0'; ++i) {
        if (ch == str[i])
            ++count;
    }

    printf("Frequency of %c = %d", ch, count);
    return 0;
}
