Consider the following method: public void printVowels(String str) { str = str.toLowerCase(); for (int i = 0; i < str.length(); i++) { char ch = str.charAt(i); if (ch == 'a' || ch == 'e' || ch == 'i' || ch == 'o' || ch == 'u') { System.out.print(ch + " "); } } } Assume that the method printVowels("OpenAI") appears in a method in the same class. What is printed as a result of the method call?
