New to Java

Hi


I get this error : how to solve it :

java.io.IOException: Stream closed
at java.io.BufferedWriter.ensureOpen(Unknown Source)
at java.io.BufferedWriter.flushBuffer(Unknown Source)
at java.io.BufferedWriter.flush(Unknown Source)
at tableA.main(tableA.java:546)

} catch (IOException e) {
				// TODO Auto-generated catch block
				e.printStackTrace();
			}
			finally{
				try
				{
					if(writeProv != null){
						writeProv.flush();
						writeProv.close();
					}
					if(fw != null)
						fw.close();
				}
				catch(IOException e)
				{
					e.printStackTrace();
				}
			}
