Why does this code keep giving me an Null Pointer Exception Error

Question

I am trying to find the shortest title in a file using java programming. I am working with a CSV file. It has Rotten Tomato ratings of movies with Robert De Niro. There are 87 records. Each record has Year, Rating, Title. Here is a link to the file if that helps: https://people.sc.fsu.edu/~jburkardt/data/csv/deniro.csv. I have written the code but i keep getting an error in the output. I can't seem to figure out where the problem is.

I used this code:

private static void summary(String summaryCsv) throws MalformedURLException,
            IOException {
        URL website = new URL("https://people.sc.fsu.edu/~jburkardt/data/csv/deniro.csv");
        Scanner inputStream = new Scanner(new InputStreamReader(website.openStream()));

        String[] csvData = new String[1024];
        int i = 0, j = 0;
        String[] title = new String[1024];
        while (inputStream.hasNextLine()) {

            String s = inputStream.nextLine();
            String[] strArray = s.split(", ");
            if (strArray.length == 3) {
                title[j] = strArray[2];
            }

            csvData[i++] = s;
            j++;
        }
        inputStream.close();

        System.out.println("Total number of records: " + getLength(csvData));
        System.out.println("Shortest title: " + shortest(title));
    }

    public static <T> int getLength(T[] arr) {
        int count = 0;
        for (T el : arr) {
            if (el != null) {
                ++count;
            }
        }
        return count - 2;
    }

    public static String shortest(String words[]) {
        if (null == words || words.length < 1) {
            return "";
        }
        String smallest = words[0];
        for (int i = 1; i < words.length; i++) {
            if (words[i].length() < smallest.length()) {
                smallest = words[i];
            }
        }
        return smallest;
    }

This is the code in the class that tests it:

public class tests {
    public static void main(String[] args) throws Exception {

        String[] argz = new String[]{"summary", "csv", "den.csv"};
        MovieSummary.main(argz);
    }
}

It should give the following output: Total number of records: 87 Shortest title: Hi

But instead it gives the following output: Total number of records: 87 Exception in thread "main" java.lang.NullPointerException: Cannot invoke "String.length()" because "words[i]" is null
