Easy task. Just one Stream API pipeline.

Two things likely to trip you up on this task that, on the surface, looks extremely simple: 1. FileReader.read returns a character in numeric form. You must cast it correctly to append it to a string. 2. The word "world" must appear by itself, not as part of another word. So you can't just loop through String.indexOf.

A more precise description of the task is: - "The file contains words separated by punctuation marks and/or whitespaces." - the words "world" count only in lower case. - "worlds", "worldly" : these do not count.

Hey Crew. So what worked for me on this one was the following. Convert the file to an ArrayList<Character> charArray... containing each char in the file. Convert charArray into ArrayList<String> words using the ASCII value for characters. (97 to 122 for lower case.. Character.toLowerCase() ) Check if each of those words equals "world" using a for loop. Hope this helps!

"Determine why the program found more instances of the word "world " than exist in the file." I don't know why? when I check it with file on my PC it works.
