SAVE CODE AS   "VowelsInString.java"

import java.util.Scanner;

public class Slip2q1 {
    public static void main(String[] args) {
        Scanner scanner = new Scanner(System.in);
        System.out.println("Enter a string to find vowels on it.");
        String user_string = scanner.nextLine();
        scanner.close();
        int vowel_count = 0;
        for(int i=0;i<user_string.length();i++){
            if(user_string.charAt(i)=='a' ||user_string.charAt(i)=='e'
                    ||user_string.charAt(i)=='i' ||user_string.charAt(i)=='o'
                    ||user_string.charAt(i)=='u' ||user_string.charAt(i)=='A'
                    ||user_string.charAt(i)=='E' ||user_string.charAt(i)=='I'
                    ||user_string.charAt(i)=='O' ||user_string.charAt(i)=='U'){
                vowel_count++;
                System.out.println("Vowel found ("+user_string.charAt(i)+") at index "+i);
            }
        }
        if (vowel_count == 0){
            System.out.println("Vowel not found in given string.");
