Question

Input a phrase from the keyboard. For example, input could be:

Today is a rainy day, but the sun is shining.

Your program should count (and output) the number of "a"s in the phrase, the number of "e"s, the number of "i"s , the number of "o"s, the number of "u"s, and the total number of vowels.

Note: The number of "a"s means the total of uppercase and lowercase "a"s etc.

Also: the vowels are a,e,i,o,u.

In the above example your output should be:

The phrase is "Today is a rainy day, but the sun is shining."

The number of a's: 4

The number of e's: 1

The number of i's: 5

The number of o's: 1

The number of u's: 2

The total number of vowels is: 13

Code:

import java.util.*;
class Vowel{
   public static void main(String[] args) {
       Scanner s =new Scanner(System.in);
       System.out.println("Enter a phrase");
       String str=s.nextLine();
       int no_a=0;
       int no_e=0;
       int no_i=0;
       int no_o=0;
       int no_u=0;
       int total=0;

       for(int i=0;i<str.length();i++){
           if(((str.charAt(i))=='a')||((str.charAt(i))=='A')){
               no_a++;
               total++;
           }
           else if(((str.charAt(i))=='e')||((str.charAt(i))=='E')){
               no_e++;
               total++;
           }
           else if(((str.charAt(i))=='i')||((str.charAt(i))=='I')){
               no_i++;
               total++;
           }else if(((str.charAt(i))=='o')||((str.charAt(i))=='O')){
               no_o++;
               total++;
           }else if(((str.charAt(i))=='u')||((str.charAt(i))=='U')){
               no_u++;
               total++;
           }
           else{
               //do nothing

           }
          

       }
           System.out.println("The number of a's: "+no_a);
           System.out.println("The number of e's: "+no_e);
           System.out.println("The number of i's: "+no_i);
           System.out.println("The number of o's: "+no_o);
           System.out.println("The number of u's: "+no_u);
           System.out.println("Total Vowels are: "+total);

   }
}

Output:
