This is a simple programming-contest sort of exercise.
You "need" only two classes.
+ a Team
- knows its name (a String of at most 30 characters)
* This should be passed when the Team is created;
the rest of the program should NOT call (Team new)
and should NEVER see an un#initialize-d Team instance.
- knows the number of matches it has won, drawn, and lost
(non-negative Integers, initially zero).
- can report what it knows
- can report the total match count and point score
- can be told that it has won, drawn, or lost another match.
+ a Tournament
- has a collection of Teams that it knows by name
(a Dictionary)
- and an sequence, initially undefined.
- can read a set of match triples from a stream,
forwarding the information about wins, draws, and losses
to Team instances, which are created when a new name is found,
- can convert the values of the teams collection to a
sorted collection that is sorted by a somewhat vague order,
I chose
- descending on point score, then
- descending on wins, then
- ascending on losses, then
- ascending on name.
- can write the sorted teams to a stream in tabular form.
! Has a class method that does
(self new) read: <<source>>; sort; write: <<destination>>
Frankly, formatting the output was the hardest part.
