Question
Write a program that reads lines of input from the user and converts each line into “Pig Latin.” Pig Latin is English with the initial consonant sound moved to the end of each word, followed by “ay”. Words that begin with vowels simply have an “ay” appended.
Your program should continuously prompt the user for sentences until they enter a blank line, at which point the program should terminate.

// terminate the program when blank string is entered
if (str.isBlank() || str.isEmpty())
break;
StringBuffer solution = new StringBuffer();
String[] strArr = str.split(” “);
// extract each word fromm the sentence
for (String word : strArr) {
