Reference no: EM13161540

Write a method named isAllVowels that returns whether a String consists entirely of vowels (a, e, i, o, or u, case-insensitively). If every character of the String is a vowel, your method should return true. If any character of the String is a non-vowel, your method should return false. Your method should return true if passed the empty string, since it does not contain any non-vowel characters.
