Have the function StringChallenge(str) take the str string parameter being passed and return the number of vowels the string contains (ie. "All cows eat grass and moo" would return 8). Do not count y as a vowel for this challenge.

Examples

Input: "hello" Output: 2

Input: "coderbyte" Output: 3

Just I start the solution using java

import java.util.*;

import java.io.*;

class Main {

public static String StringChallenge(String str) {

// code goes here

return str;

}

public static void main (String[] args) {

// keep this function call here

Scanner s = new Scanner(System.in);

System.out.print(StringChallenge(s.nextLine()));

}

}
