Programming Assignment 1

Due: Saturday, 29 Feb, midnight

Implement one of these programs. You can submit either one, but not both.

1. ArrayIterator - a class that iterates over an array, skipping nulls.
   • This is easy. Requires about 15 lines of code, not counting imports.
   • Good practice using Iterator, a “cursor” to keep track of position, and throwsing an exception.
   • Assignment: https://skeoop.github.io/assignments/PA1-ArrayIterator.pdf
2. CSVReader - a class for reading data in CSV format. It parses lines and returns each line as an array of Strings using the Iterator interface.
   • This is more work, but you will learn how to read from a file and parse data using String.split() or StringTokenizer.
   • Practice using Iterator, throwing exceptions, using BufferedReader.
   • Requires 20-30 lines of code.

Individual Work

This is an individual assignment. Do not ask other students for help or share code. Please ask TAs or instructor if you need help.

Test Code

You should carefully review and test your own code. Don’t depend on instructor-provided tests. In grading we may use different tests.

• CSV Reader: please contact me for test code

Submit Early to Get Feedback

If you submit early and send email to TA and instructor, we will try to give some useful feedback so you can revise your code.
