Reading from an Array ==Tokenizer

[Andy K]

Would you please help ne. I am trying to read from an array but I keep
getting an error (Variable not defined. here is the piece of code please
help.
{StringTokenizer tokens;

tokens = new StringTokenizer(textLiner)
teamName = tokens.nextToken();
points = Integer.parsInt(tokens.nextToken());

premiership t[] = new Premiership[20];
int i;
for (i=0; i<t.length;i++);
{
t = new Premiership(teamname,points);
t.teamName = teamName;
t.points = points;
}

Of course you have to put these lines INSIDE the loop!
Furthermore, it assumes that your data is all on one line
and contains syntax errors.

What are the sytax errors in these lines then? I though by putting a ; I
am saying this is a new line.

It's "parseInt", not "parsInt".

I though by putting a ; I
am saying this is a new line.

In Java code it marks the end of a statement. What I meant is that the
*data* you're reading with the StringTokenizer must be on one line
for your code to work, team name and points alternating and separated by
the separator in "textLiner".
If each entry is on its own line (no ; necessary), which I suspect it is,
you need to read the line and create the StringTokenizer inside the loop
as well.

Thanks for your help Michael I forgot to put the loop. I alread have the
loop in my code and it looks like this:

Something up here


textLine = fileInput.readLine();
moreToRead = (textLine != null);

while (moreToRead)
{
tokens = new StringTokenizer(textLiner)
teamName = tokens.nextToken();
points = Integer.parsInt(tokens.nextToken());

premiership t[] = new Premiership[20];
int i;
for (i=0; i<t.length;i++);
{
t = new Premiership(teamname,points);
t.teamName = teamName;
t.points = points;
}

At the moment I cant even run it yet o check it its reading properly
since I have to compile it

Please help . thanks in advance

At the moment I cant even run it yet o check it its reading properly
since I have to compile it

Then do that.

teamName = tokens.nextToken();
[...]

t = new Premiership(teamname,points);

Shouldn't this one be "teamName"?

t.teamName = teamName;
t.points = points;

You probably won't be needing these two instructions, as your constructor
is -I guess- doing this already.

teamName = tokens.nextToken();

for (i=0; i<t.length;i++);
{
t = new Premiership(teamname,points);
t.teamName = teamName;
t.points = points;
}

If you posted (or read) the full error message, it would tell us (or
you) _which_ variable is not defined. Presumably it is "textLiner".
Depending on the definition of the Premiership class, it might also be
Premiership.teamName or Premiership.points.
