CSSE 220 – Object-Oriented Software Development

Homework 8

Objectives

Practice with arrays and ArrayLists.

Tasks

1. Complete the assigned reading for the next session: § 9.1–9.5. As you read, see if you can answer the self-check questions. If there is something you do not understand, make note of it so you can ask about it in class.
2. Programming:
   1. Your programming work for this assignment must be done in the ArraysListsAnd2D project inside Eclipse. Check out this project. Note that the "grace period" described in HW7 also applies to the Fractions part of this assignment.  TicTacToe should be completed by Session 9 day at 8:05 AM.
   2. (3 points) TicTacToe: Finish the in-class exercise. Postponed to HW9 because we did not get this far in class.
   3. (8 points) Fractions.  Write (in the FractionArrays class)  and test (by adding code to main() in the FractionArrays class) the following methods.

      1. /**

         * Find the largest denominator from among the Fractions in the array;

         * @param a array of Fractions

         * @return largest denominator (0 if the array is null or empty)

         */

         public static int largestDenominator(Fraction [] a)

      2. /**

         * Find and remove all occurrences of the largest fraction in a.

         * The order of the remaining elements should not be changed.

         * @param a an ArrayList of Fractions

         */

         public static void removeLargest(ArrayList<Fraction> a)

   4. Continue the Pascal Triangle exercise from HW7.
