Using the following Python code as an example, write a solution to a creating a Term Frequency program in JAVA with JAVA STREAMS instead:

With Java stream API to create a code golf simple fewest lines of code version.

NOTE: Do NOT do character by character as in the Python example; just do WORD BY WORD!

Constraints:

1. Data comes to functions in streams, rather than as a complete whole all at at once

2. Functions are filters / transformers from one kind of data stream to another

3. Program must run on command line and take an input file of text called pride-and-prejudice.txt and must output only the TOP 25 most frequent words with their counts and MUST be in order of most frequent at the top and MUST output to a new text file called output.txt NOT the command line. It must FILTER out the STOP WORDS from the list below and take the stop_words.txt file as input (not a string of words hardcoded).

stop_words.txt:

a,able,about,across,after,all,almost,also,am,among,an,and,any,are,as,at,be,because,been,but,by,can,cannot,could,dear,did,do,does,either,else,ever,every,for,from,get,got,had,has,have,he,her,hers,him,his,how,however,i,if,in,into,is,it,its,just,least,let,like,likely,may,me,might,most,must,my,neither,no,nor,not,of,off,often,on,only,or,other,our,own,rather,said,say,says,she,should,since,so,some,than,that,the,their,them,then,there,these,they,this,tis,to,too,twas,us,wants,was,we,were,what,when,where,which,while,who,whom,why,will,with,would,yet,you,your

Correct output will look like this if written correctly so ENSURE THE STOP WORDS ARE PROPERLY REMOVED TO PROVIDE THE FOLLOWING OUTPUT BEFORE POSTING SOLUTION OR IT WILL BE DOWNVOTED!:

output.txt:

mr - 786

elizabeth - 635

very - 488

darcy - 418

such - 395

mrs - 343

much - 329

more - 327

bennet - 323

**PYTHON CODE VERSION BELOW**:

import sys

import operator

import string

def characters(filename):

for line in open(filename):

for c in line:

yield c

def all_words(filename):

start_char = True

for c in characters(filename):

if start_char == True:

word = ""

if c.isalnum():

# We found the start of a word

word = c.lower()

start_char = False

else:

pass

else:

if c.isalnum():

word += c.lower()

else:

# We found end of word, emit it

start_char = True

yield word

def non_stop_words(filename):

stopwords = set(open(

'../stop_words.txt').read().strip(' ').split(',') + list(string.ascii_lowercase))

for w in all_words(filename):

if not w in stopwords:

yield w

def count_and_sort(filename):

freqs, i = {}, 1

for w in non_stop_words(filename):

freqs[w] = 1 if w not in freqs else freqs[w]+1

if i % 5000 == 0:

yield sorted(freqs.items(), key=operator.itemgetter(1), reverse=True)

i = i+1

yield sorted(freqs.items(), key=operator.itemgetter(1), reverse=True)

#

# The main function

#

for word_freqs in count_and_sort(sys.argv[1]):

print("-----------------------------")

for (w, c) in word_freqs[0:25]:

print(w, '-', c)

**THIS IS MY 7th ATTEMPT AT GETTING A WORKING SOLUTION FOR THIS QUESTION, SO MAKE SURE THE PROGRAM WILL FULLY WORK WITHOUT ADJUSTMENTS BEFORE SUBMITTING SOLUTION OR I WILL DOWNVOTE YOUR ANSWER.**

*** BE EXTRA CAREFUL WITH CODE FOR PARSING THE WORDS AND STOP WORDS TO ENSURE THE CORRECT OUTPUT FREQUENCY IS OBTAINED AS ABOVE***
