Assignment #4 -- Pig Latin web page translator

Due: Tues, Oct 22

Objective

This assignment will involve practice with characters and strings, using the libraries discussed in class (String, StringBuilder, Character), as well as basic File I/O (with text files).

Task

Write a program in a class called WebToPigLatin (filename WebToPigLatin.java) that will translate web page content (html files) to Pig Latin versions of the page.

Requirements

1) Command structure

The program should take its input information through two command line parameters. The usage format is:

  java WebToPigLatin inputFile outputFile

Example:

  java WebToPigLatin page1.html pigpage1.html

In the above example, the input page is page1.html. The results should be written to the file pigpage1.html.

If the command to the program is given incorrectly, print out a usage message like:

  Usage: java WebToPigLatin inputFile outputFile
  Must have two command-line parameters

and abort.

2) Pig-Latin rules

For our purposes, we will use the following as the rules for translation of a word into "Pig Latin":

A word to be translated is a consecutive sequence of letters (a-z, A-Z) or apostrophes (must start with a letter), containing at least one vowel (or y in a vowel position).
Examples: Zebra , doesn't , apple, rhythm
If a word starts with a vowel, the Pig Latin version is the original word with "way" added to the end
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.
The letter 'y' should be treated as a consonant if it is the first letter of a word, but treated as a vowel otherwise.
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).

Examples of pig latin translations of words, under these rules:

Word	PigLatin version
Flower	Owerflay
yellow	ellowyay
bypass	ypassbay
apple	appleway
Igloo	Iglooway
string	ingstray
Hamburger	Amburgerhay
Rhythm	Ythmrhay
queen	ueenqay
zippity	ippityzay

3) File handling rules

For the purposes of translating only the CONTENT of an html file (i.e. a web page), please observe the following requirements:

Anything that appears inside of html tags is not content, so it should not be converted. Example:
```
  <font size="-1" face="Arial, Helvetica, sans-serif">Yadda Yadda</font>
```
In this tag, only "Yadda Yadda" is content. The rest is not translated.
Any item that fits the pattern of &text; is not content. These are special html markers for placing symbols like quotes and ampersands, that otherwise have special meaning to browsers. Example:
```
  &nbsp;Hello there		// only "Hello there" is content
  &quote;Hello there&quote;	// only "Hello there" is content
```
Do not consider punctuation (other than apostrophes) to be parts of words (i.e. they should not be part of word translations). Punctuation will still appear in the content in the appropriate places, after translation. Example:
```
   The attentive, brilliant Java student's friend was happy.
```
translates to
```
   Ethay attentiveway, illiantbray Avajay udent'sstay iendfray asway appyhay.
```
Numbers on web pages are obviously not translatable, so leave them as-is.
Abbreviations with no vowels in them are not translatable, so leave them as-is.
Anything from the html file that is not translated to Pig Latin should still appear in the file as-is. i.e. the intent is that the resulting web page should still appear the same as the original, simply with all of the content words converted to Pig Latin.

General Requirements and Hints

Your code should be readable and well-documented
You may make use of any of the features of the String, StringBuilder and Character class libraries. Each of these is in the java.lang package.
For File I/O, recommended libraries are:
- java.util.Scanner
- java.io.FileReader -- for reading single characters at a time
- java.io.FileWriter
- java.util.Formatter
Pack your program into a runnable jar file called hw4.jar for submitting.

Submitting:

Pack the program and source code into a runnable jar file called hw4.jar for submitting.
