File Reader/Writer problem

[Vsam hr]

I have written a I/O code wherein the I/O is done using

 BufferedReader br = new BufferedReader(new FileReader("<some file>"); 
BufferedWriter bw = new BufferedWriter(new FileWriter("<some file>"); 

The File which I am reading from contains large no. of records.Each records contains a few columns. On reading the records and am modifying them and writing them to the Output file. I am using while loop for reading each record.

 while((line=br.readLine()) != null)   

The problem arises for the last record. When writing the last record into the output file, only few columns get written. The entire last record isnt written. This causes problems when i want to read this output file as the last record is not complete.
I am also closing the BufferedWriter using bw.close();

Please help in explaining why only the last record isnt being completely written.
Thanks in advance

Try flushing the Writer before closing it.

To quote the Javadoc for BufferedWriter.close()

Closes the stream, flushing it first.

The implication is that if your solution works then there is a bug in BufferedWriter.

My bet is that the OP has a bug in his code but we don't have access to it.
