Assignment #8 - File I/O

Task

Write a program that translates an English text file into "Pig Latin". The rules we will use for Pig Latin translation are given below.

Filename should be

• PigLatin.java

Program Requirements

1. The input file and the output file names are to be specified as command line arguments. Format:

       java PigLatin inputfile outputfile
   

   Sample call:

       java PigLatin letter.txt outfile.txt
   

   This call will read in the input file letter.txt, and it will write the Pig Latin translation of this file to outfile.txt.
    
2. Required error checking and exception handling
   • If 2 command line arguments are not passed in, print the following usage error message, and abort the program:

         usage: java PigLatin infile outfile
       

   • If the given input file is not found (i.e. a FileNotFoundException is thrown), you should catch the exception and print the following error message before letting the program quit:

         Error: Input file not found
       

   • You do NOT need to do error checking on the output file. If there is an existing file with the same name, it will simply be overwritten.
   
   
3. Assuming that the error conditions above do not occur, the program should read the input file and write a translation to Pig Latin to the output file, using the rules described below. Translation is done on words. Characters that are not part of words (punctuation, spaces, newlines, etc) should be written to the output file as-is (no change).
4. You may use any of the Stream classes discussed in lecture, as well as Character, String, StringBuffer, and/or StringTokenizer. You do not necessarily need all these classes, but you may use any of them that you like. For the Stream classes, be sure to import the java.io package.

Pig Latin Translation Rules

1. A word is a consecutive sequence of letters (a-z, A-Z) or apostrophes. Note that this means hyphenated words are simply treated as two words. Examples: Zebra , doesn't , apple
2. If a word starts with a vowel, the Pig Latin version is the original word with "way" added to the end
3. If a word starts with a consonant, or a series of consecutive consonants, the Pig Latin version transfers all consonants up to the first vowel to the end of the word, and adds "ay" to the end.
4. The letter 'y' should be treated as a consonant if it is the first letter of a word, and treated as a vowel otherwise.
5. If the original word is capitalized, the new Pig Latin version of the word should be capitalized in the first letter (i.e. the previous capital letter may not be capitalized any more).

  are		-->	areway
  each		-->	eachway
  rabbit	-->	abbitray
  yellow	-->	ellowyay
  bygone	-->	ygonebay
  stretch	-->	etchstray
  Russia	-->	Ussiaray
  Athena	-->	Athenaway
