Get File Size problem

Question

Hi,
I am using a BufferedWriter to write into a file, and I need to monitor the file size. If the file exceeds certain size, then I need create another file. Here is my code:
File file = new File ("myname");
file.createNewFile();
BufferedWriter bwr = new BufferedWriter (new FileWriter());
while (my conditions...)
System.out.print (file.length());
if (file.length > 1000)
bwr.close();
file = new File("anothername");
file.createNewFile();
bwr = new BufferedWriter (new FileWriter(file));
bwr.write("msg");
bwr.newLine();
Although from the file system, I found the file has been over 17K, but the application although print 0 as the file.length(). Is there anything I did wrong?
Thanks!

Answer 1

I suspect the problem is because your creating a new file and then writing to it. And to make it even more fun, your using a buffered writter, so who knows whats going on behind the scenes. Using a new File object may do the trick, but i doubt it.
Is there any reason why you dont count what you have written? its a new file and you know what your writing, so just calculate what you have written so far.
The other option is to use RandomAccessFile. You would use getFilePointer() which returns the offset in the file your up to.
