Description
Problem 1
Create a class called DuplicateRemover. Create an instance method called remove that takes a single
parameter called dataFile (representing the path to a text file) and uses a Set of Strings to eliminate
duplicate words from dataFile. The unique words should be stored in an instance variable called
uniqueWords. Create an instance method called write that takes a single parameter called outputFile
(representing the path to a text file) and writes the words contained in uniqueWords to the file pointed to
by outputFile. The output file should be overwritten if it already exists, and created if it does not exist.
Create a separate class called Application that contains a main method which illustrates the use of
DuplicateRemover by calling both the remove and write methods. Your input file must be called
problem1.txt and your output file must be called unique_words.txt. You will not receive credit if you
use different file names, as my graders will not modify your code to make it work with their test files.
Your program should work on any text file. The TA’s will provide their own version of problem1.txt when
they run your code.
Problem 2
Create a class called DuplicateCounter. Create an instance method called count that takes a single
parameter called dataFile (representing the path to a text file) and uses a Map of Strings to count how
many times each word occurs in dataFile. The counts should be stored in an instance variable called
wordCounter. Create an instance method called write that takes a single parameter called outputFile
(representing the path to a text file) and writes the contents of wordCounter to the file pointed to by
outputFile. The output file should be overwritten if it already exists, and created if it does not exist.
Create a separate class called Application that contains a main method which illustrates the use of
DuplicateCounter by calling both the remove and write methods. Your input file must be called
problem2.txt and your output file must be called unique_word_counts.txt. You will not receive credit if
you use different file names, as my graders will not modify your code to make it work with their test files.
Your program should work on any text file. The TA’s will provide their own version of problem1.txt when
they run your code.
