Here is my code. But in myProgrammingLab there are a few unexpected results.

import java.util.Scanner;

public class PigLatin {

public static String convertWord(final String englishWord) {

for (int i = 0; i < englishWord.length(); i++) {

if (isVowel(englishWord.charAt(i)))

return (englishWord.substring(i) + "-" + englishWord.substring(0, i) + "ay");

}

return englishWord + "-ay";

}

public static boolean isVowel(final char c) {

return "aeiouAEIOU".contains(String.valueOf(c));

}

public static void main(final String[] args) {

final Scanner console = new Scanner(System.in);

String phrase;

do {

System.out.print("Enter a sentence to translate:");

phrase = console.nextLine();

if (phrase.trim().length() > 0) {

String pigLatinPhrase = "";

final String words[] = phrase.trim().split(" ");

for (int i = 0; i < words.length; i++) {

pigLatinPhrase += convertWord(words[i]) + " ";

}

System.out.println(""+pigLatinPhrase);

}

} while (phrase.trim().length() > 0);

console.close();

}

}
