Thanks all

@Richard��

I did tried that way in the solution I put on the net.
But I get stuck at the point that if I update a record in the Team Class the collection at the Tournament class was not updated.

But right now , I try a new way to make it work that a new team is made and returned or a team is returned if that team is known.

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.

hello,

I think I have to reconsider my classes and reponsibilities

Right now Im thinking of this

Team :�� responsinble for team properties
Ranking : reponsibilities�� for checking if a team is in the ranking and
updating the team statics
Tournament :�� parsing the ganes and call the right functions on Ranking

Can this work or am In making to much classes
