Practical 8 : Create a class which ask the user to enter a sentence, and it should display count of each vowel type in the sentence. The program should continue till user enters a word “quit”. Display the total count of each vowel for all sentences.

Program:

import java.util.Scanner;

public class practical8

{

    public static void main(String[] args)

    {

        System.out.println("Enter the word 'quit' to end this program.");

        String str;

        int x = 0, A = 0, E = 0, I = 0, O = 0, U = 0;

        char ch;

        Scanner in = new Scanner(System.in);

        while (x < 1)

{

            str = in.next();

            if (str.equals("quit"))

{

                x++;

                in.close();

                break;

            }

 else {

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

{

                    ch = str.charAt(i);

                    if (ch == 'a' || ch == 'A')

      {

                        A++;

                    }

     else if (ch == 'e' || ch == 'E')

      {

 E++;

                    }

       else if (ch == 'i' || ch == 'I')

      {

                        I++;

                    }

       else if (ch == 'o' || ch == 'O')

      {

                        O++;

                    }

        else if (ch == 'u' || ch == 'U') {

                        U++;

                    }

                }

            }

        }

        System.out.println("Vowels A or a: " + A + "\nVowels E or e: " + E + "\nVowels I or i: " + I);

       System.out.println("Vowels O or o: " + O + "\nVowels U or u: " + U + "\nTotal Vowels: " + (A + E + I + O + U));

    }

}

Output:
