File I/O strange behavior !!!!!!!

Question

Hello everyone, I have been writing a small program that parses a file and writing to
another file. what I basically want to do is to read from a file named 10130.txt containing
around 50 or 60 lines
19971021 10130 -9 0 0 0 0 -9 0 -9 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0
the output file should contain
19971021 00 -9
19971021 01 0
19971021 02 0
19971021 03 0
19971021 04 0
19971021 05 -9
19971021 06 0
19971021 07 -9
19971021 08 0
19971021 09 0
19971021 10 0
19971021 11 0
19971021 12 0
19971021 13 0
19971021 14 0
19971021 15 0
19971021 16 0
19971021 17 0
19971021 18 0
19971021 19 0
19971021 20 0
19971021 21 0
19971021 22 0
19971021 23 0
the previous output should be for each line from the input file.so if I have 50 lines in i/p file then
the o/p file should contain 50x24 lines.
The code I have written works very fine till almost the middle of the i/p file and then gives me the following
exception:
java.util.NoSuchElementException
     at java.util.StringTokenizer.nextToken(StringTokenizer.java:259)
     at Pras.parseFile(Pras.java:55)
     at Pras.main(Pras.java:22
I really dont knw whats wrong

the part of the i/p file where the code seems to throw the exception is

I really dont knw whats the problem since the code works very fine till the specfied line in the i/p file.
that line have the same no. of tokens and spacing as all the previous lines so no wrong parsing here (I think).
Any help would be appreciated?
thanx in advance.

Answer 1

Maybe some error checking would help:
    while ((text = br.readLine()) !=null)
        StringTokenizer stk = new StringTokenizer(text);
        if (stk.countTokens() < 26)
            continue;
        ...Next time please paste your code between code tags exactly like this:
&#91;code&#93;
your code
&#91;/code&#93;
Thank you
