public void getWordsFromFile(String filename) throws IOException

This method should follow this algothrithm:

For every word in the file search for the word in the ArrayList, if it exists increment its count, else add the word to the ArrayList.

Remember it is a scanner so here's an example text file

exampleText.txt-

First word second word

Output should look like

first(1) word(2) second(1)

Ignore uppercase and lowercase so "First" and "first" is the same word.

Create more test cases if needed.

Don't use hashmap or map.
