Your program will expect a file name to be on the commands line when the program is launched:

C:> java Project2 dictionary.txt

Your Project2.java defines a small array of String. As your loop in main reads in Strings from the args[0] file, the dictionary, it appends them to the end of the array. When the array gets full a call is made to upSize the array and then resume appending Strings into it until the file is exhausted and all Strings are loaded into the array. You must fill in the upSize() method. Each time an upsize is performed, a line will be printed to the terminal indicating the new .length of the array.

As each string is read in you will update a counter of how many vowels in total have been found so far in all the strings. A vowel is 'a', 'e', 'i', 'o', or 'u'.

After the args[0] file is closed, main will call downSize() to shrink-wrap the array around the data so there are no empty cells at the end. You must fill in this method also. After downsizing the array main will print out the .length after downsizing and the wordCount and the vowelCount.

The last method main will call is findFirstDupe() which you must fill in. This method will search the array looking for the first occurrence of a String that is a duplicate of a previous String. Do not sort the array or alter the ordering of any of the strings inside the array. The method must return the String that is duplicated in the array. This string will be printed in main.
