Question

Use the method:

public static String convertToPigLatin (String inStr) {
String ret = "";
char first = inStr.toLowerCase().charAt(0);
if(first == 'a' || first == 'e' || first == 'i' || first == 'o' || first == 'u') {
ret = inStr.toLowerCase() + "way";
}
else {
ret = inStr.substring(1).toLowerCase() + first + "ay";
}
return ret;
}

Write a program that
1) Open a file for input called pigLatinIn.txt, which will be provided to you. This file will consist of one English word per line.
2) Open a file for output called pigLatinOut.txt.
3) Your program will then read the input file, use the convertToPigLatin() method to determine the pig Latin equivalent to the word, then write the following to the output file:

English word Pig Latin Word
------------ --------------
cabin abin-cay
apple apple-way

4) Print out the results in all lower case.
