/**

* Calculates the count of each word in the list of lines.

* Traverses the list of lines, and keeps track of the count of each word.

* Stores each word as a key and its associated count as a value in the HashMap wordCount.

*

* Note, the words (keys) are case-sensitive.

* e.g. "Hello" is considered a different word (key) than "hello".

* e.g. "UFO" is considered the same word as "UFO".

*

* Hint(s):

* - Traverse the list of lines and split each one into an array of words (strings). Use the words as keys and

* the associated counts as values in the HashMap wordCount.

*

* Example(s):

* - If the list of lines contains:

* "war and the"

* "war the peace peace"

* "the war the"

*

* Calling generateWordCounts() would populate the HashMap wordCount with:

* ("war", 3), ("and", 1), ("the", 4), ("peace", 2)

*

* Example(s):

* - If the list of lines contains:

* "War and the"

* "war the Peace peace"

* "thE war The"

*

* Calling generateWordCounts() would populate the HashMap wordCount with:

* ("War", 1), ("war", 2), ("and", 1), ("the", 2), ("The", 1), ("thE", 1), ("Peace", 1), ("peace", 1)

* Gets a list of words that appear a particular number of times, indicated by the given threshold.

*

* Hint(s):

* - For each word (key) in the wordCount map, check if the associated word count (value) is >= threshold.

*

* Example(s):

* - If the list of lines contains:

* "war and the"

* "war the peace peace"

* "the war the"

*

* Calling getWordsOccuringMoreThan(3) would return an ArrayList with: "war", "the"

* Because "war" appears 3 times and "the" appears 4 times.

*

* Example(s):

* - If the list of lines contains:

* "War and the"

* "war the Peace peace"

* "thE war The"

*

* Calling getWordsOccuringMoreThan(2) would return an ArrayList with: "war", "the"

* Because "war" appears 2 times and "the" appears 2 times.

*

* Example(s):

* - If the list of lines contains:

* "War and the"

* "war the Peace peace"

* "thE war The"

*

* Calling getWordsOccuringMoreThan(-1) would return an ArrayList with:

* "War", "war", "and", "the", "The", "thE", "Peace", "peace"

* Because all words appear more than -1 times.
