Write a method (For this you will need to submit a coding listing and test output file). public int countVowels(String str). that returns a count of all vowels in the string str. Vowels are the letters a, e, i, o, and u, and their uppercase variants. Use a helper method isVowel(char ch) that checks whether a character is a vowel. Your program should be interactive (use Scanner). For optional extra credit create a second version where your countVowels method is declared as static: public static int countVowels(String str).
