Write a program to accept a sentence in mixed case. Find the frequency of vowels in each word and print the words along with their frequencies in separate lines.

Sample Input: We are learning scanner class
Sample Output:
We are learning scanner class
Word Frequency of vowels
we 1
are 2
learning 3
scanner 2
class 1

import java.util.Scanner;

public class Assignment19

{

    public static void main(String args[]) {

        Scanner in = new Scanner(System.in);

        System.out.println("Enter a sentence :");

        while (in.hasNext()) {

            String orgWord = in.next();

            String word = orgWord.toUpperCase();

            if (word.equals("."))

                break;

            int vowelFreq = 0;

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

                if (word.charAt(i) == 'A' ||

                    word.charAt(i) == 'E' ||

                    word.charAt(i) == 'I' ||

                    word.charAt(i) == 'O' ||

                    word.charAt(i) == 'U')

                    vowelFreq++;

            }

            System.out.println(orgWord + "\t\t" + vowelFreq);

        }

    }

}
