BufferedWriter

Download java eBook

If you try to write from a BufferedWriter (using BufferedWriter.write()) after closing the BufferedWriter (using BufferedWriter.close()), it will throw an IOException.
The BufferedWriter(Writer) constructor does NOT throw an IOException. However, the FileWriter(File) constructor throws a FileNotFoundException, which extends IOException. So catching IOException will also catch FileNotFoundException, there is never a need for a second catch statement unless you plan on doing something different with the FileNotFoundException.
