How to write to a file and save it dynamically in java

Question

I have a requirenment to write to a file rather than in System.out.println and save it at same time so that user can see the progress anytime by opening the file.

Right now I am using following code

     FileWriter fstream = null;
        File file1 = new File(logFile);
        fstream = new FileWriter(file1);
        out = new BufferedWriter(fstream);
               out.write(msg);
     out.write("\n");

but it does not save the contents to the file unless I say Out.close();

FYI - 1. This is a Java EE application code. 2. I donot want to user Log4jLogger

Is there any simpler way to do this? Any pointers?

Answer 1

You don't need to call close() - just call flush().

Flushes this output stream and forces any buffered output bytes to be written out.
