Hi Friend,

Try this:

import java.util.*;
class CountVowels{
  public static void main(String args[]){
  Scanner input=new Scanner(System.in);
  System.out.println("Enter Word:");
  String st = input.nextLine();
  int count = 0; 
    for (int i = 0; i < st.length(); i++) {
        char c = st.charAt(i);
        if (c=='a' || c=='e' || c=='i' || c=='o' || c=='u') {
        count++;
        }
    }
    System.out.println("There are" + " " + count + " " + "vowels in a word");
}
}

Thanks
