get no by character in java code example

Example 1: counting the number of characters in a string java

public static void main(String[] args) {
		int wordCount = 0;
		String word = "hill";
		for (char letter = 'a'; letter <= 'z'; letter++) {
			for (int i = 0; i < word.length(); i++) {
				if (word.charAt(i) == letter) {
					wordCount++;
				}
			}
			if (wordCount > 0) {
				System.out.println(letter + "=" + wordCount);
				wordCount = 0;
			}
		}
	}

Example 2: 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
