ICS 211 Homework H03: Sortable Beer List (Array implementation).

Purpose

Our first abstract data structure is the List. For this homework assignment we are going to implement a sortable list using an array to store the items in the list. This assignment should give you more practice with Eclipse and implementing an interface. We will also use our implementation of the list as a member variable and learn about delegation.

Tasks

1. Create a package named edu.ics211.h03

This is where we will put all our classes for homework 03.

2. Create a class named SortableList that implements the IList211 and ISortableList interfaces

public interface IList211<E> {
  E get(int index);
  E set(int index, E element);
  int indexOf(Object obj);
  int size();
  boolean add(E e);
  void add(int index, E element);
  E remove(int index);
}

public interface ISortableList<E>{
  void insertionSort(Comparator<E> compare);
  void bubbleSort(Comparator<E> compare);
  void selectionSort(Comparator<E> compare);
  int getNumberOfSwaps();
  int getNumberOfComparisons();
  double getSortTime();
}

The SortableList must use an array to store the items in the list.

Use the Comparator to compare the items in the list. The sort methods should sort the list in ascending order, smallest at the beginning, largest at the end.

3. Create a SortableBeerList that implements IList211 and automatically sorts the list of Beers

The class SortableBeerList implements IList211<Beer> and has:

A private SortableList<Beer> member variable. This is how we are going to store and sort the beers.
A constructor that takes a Comparator<Beer> as the parameter. This is how the SortableBeerList will decide the order of the beers.
All the methods of IList211. It can delegate the operations (methods) to the SortableList member variable.

4. Create your own JUnit tests for SortableList.

Create the JUnit test class SortableListTest.

Please thoroughly test your code and briefly discuss your testing strategy. Make sure that you test the different sorting algorithms.

We are going to use the SortableBeerListTest.java JUnit tests to evaluate your SortableBeerList class for correctness.

Grading Rubric

Criterion	Excellent (100%)	Satisfactory (75%)	Borderline (50%)	Unsatisfactory (25%)	Poor (0)
Adherence to standards - 2 points Does it conform to standards in every detail?	No errors.	Minor details of the assignment are violated, or poor choices are made where the assignment is unclear.	Significant details of the assignment or the underlying program intent are violated, but the program still fulfills essential functions.	Significant details of the assignment or the underlying program intent are violated, but the program still fulfills some essential functions.	Misses the point of the assignment.
Breakdown (modular design) - 1 point Does it demonstrate good modular design?	No errors.	1-3 minor errors.	> 3 minor errors OR 1 major error.	2 major errors	> 2 major error.
Correctness of code - 4 points Does it work? Does it pass JUnit?	Passes all tests.	Works for typical input, may fail for minor special cases.	Fails for typical input, for a minor reason.	Fails for typical input, for a major reason.	No.
Documentation, and style - 2 points Is it clear and maintainable? Does it pass CheckStyle?	No errors.	1-3 minor errors.	> 3 minor errors OR 1 major error.	2 major errors	> 2 major error.
Efficiency of code - 1 point Does it use the Java features well?	No errors.	1-3 minor errors.	> 3 minor errors OR 1 major error.	2 major errors	> 2 major error.
