help constructing an array

[jibb]

hi, i have an assugnment where i need to read in football results from a text file output, total statistics, (games played & goals scored)output stats for a specific team, and then create a league table based on the results. the only task left is the league table. i have tried and tried to do this but i just cant get it to work it outputs every result to a new line of the array, even if its a team that has played before.
heres what ive done so far:

Read this:

http://www.codeguru.com/forum/showthread.php?t=217745

and try again.

Think of this from my perspective.

I come to read this post, and i see [you] post a message which describes a word problem about creating a league table based on the results, followed by a bunch of un-formatted code. This is where i stopped reading.

1) You haven't bothered to read the submission guidelines, and have put the most minimal effort in trying to offer any information to someone who you are hoping to help you with no form of repayment other than a digital 'thank you'.

2) I don't know what a league table is, and i don't care what a league table is. I don't care about the results either. This has nothing to do with Java, and is irrelevant to your real problem which you haven't described.

[dlorde]

Bluntly put, but fair comment - I stopped reading just where you did.

The OP didn't even ask a question...

To help fair to him the title of his post is "help constructing an array," but he shouldn't have tried to get someone to solve his homework for him. No one is going to go through the whole program for you dude!

Constructing an array is a fundamental question you should already know when attempting to write this program. You can always google up java array.

If the OP needs help constructing an array then who wrote this line of code?
Table [] teams = new Table[(lineCounter.getLineNumber()*2)];

Table [] teams = new Table[(lineCounter.getLineNumber()*2)];That was Voodoo magic. Copy/paste artifacts.
