Practice WOD: File IO CountLines

Prior to starting this WOD, you might want to familiarize yourself with File IO in Java 7.

Instructions

1. Start your timer.
2. Download this page onto your local computer, and name it webpage.html.
3. In Eclipse, create a project called FileIO-CountLines.
4. Enable Checkstyle for this project.
5. Write a program that reads in webpage.html, determines how many lines are in that file, and writes that integer to System.out.

When finished, stop your timer, and record how many minutes it took you to complete the WOD. Your program must satisfy our coding standards.

Rx: <10 min Av: 10-15 min Sd: 15-20 min DNF: 20+ min

Demonstration

Once you’ve finished doing the WOD a single time, watch me do it:

Standard WOD Caveats

You’ll learn significantly less from watching me solve the WOD if you haven’t attempted the WOD yourself first.

While it’s an achievement to finish the WOD no matter how long it takes, you might experience “diminishing returns” if you work longer than the DNF time. Thus, it might be strategic to stop working at the DNF time and watch my solution.

After watching my solution, I recommend that you repeat the WOD if you have not achieved at least Av performance. If so, be sure to:

• Delete your old project so you cannot refer to it;
• Don’t look at my screencast while you WOD; and
• Reset your timer.

Feel free to keep trying until you make Rx if that’s of interest to you.
