Java 20 most frequent words in a text file. Words are supposed to be stored in array that counts eah word.

Write a program that will read an article, parse each line into words, and keep track of how many times each word occurred. Run this program for each of the two articles and print out the 20 most frequently appearing words in each article.

You may think you need to use a StringTokenizer, but it turns out that is old programming. The better thing to use is string.split(regex)

Example of text to use:

Trumps action came just weeks before the period starting on Nov. 1 when individuals have to begin enrolling for 2018 insurance coverage through the laws marketplaces.
