Question

*Note* This is a beginner introduction course to Java & a this is a java Program*

Write a complete program using two arrays, upper and lower to keep the upper

and lower alphabet respectively.

Ask the user to enter string example: This is a hard test! bye.

Your program should parse the string and keep track of number of alphabet. Both arrays are indexed from 0 to 25. The logical way to do this is to use upper[0] to

Count the number of ‘A’, and upper[1] to count number of ‘B’ and so on. Likewise

for the lower array.

Output should look like:

A: 0            a:2

B: 0            b:1

Please do not use any advanced programing! This is an intro course.

Explanation / Answer

package org.students;

import java.util.Scanner;

public class UpperLowerArray {

   public static void main(String[] args) {
       // Declaring variables
       int len;
       String str;
       // Creating two integer type arrays
       int Upper[] = new int[26];
       int Lower[] = new int[26];

       // Scanner object is used to get the inputs entered by the user
       Scanner sc = new Scanner(System.in);

       // Getting the string entered by the user
       System.out.print("Enter the String :");
       str = sc.nextLine();

       /*
       * count upper case and lower case characters in the string and
       * increment the count in the arrays
       */
       for (int i = 0; i < str.length(); i++) {
           if ((int) (str.charAt(i)) >= 65 && (int) (str.charAt(i)) <= 90) {
               Upper[((int) (str.charAt(i))) - (65)]++;
           } else if ((int) (str.charAt(i)) >= 97
                   && (int) (str.charAt(i)) <= 122) {
               Lower[(int) (str.charAt(i)) - 97]++;
           }
       }

       // Displaying the upper and lower character frequencies
       for (int i = 0; i < 26; i++) {
           System.out.printf("%c:%d %c:%d ", (65 + i), Upper[i], (97 + i),Lower[i]);
       }

   }

}
