Thread: The output file is empty

Hi,

I have an output file which should contain some total values from calculations, but at the end it is empty.

Here is my code in the try catch block:

 BufferedWriter bwArea = new BufferedWriter(new FileWriter("." + ToolKit.fileSeparator() + OUTPUT_FILE_AREA));
            bwArea.close();

in the method after that I have:

 PrintWriter outArea = new PrintWriter(new BufferedWriter(
                                new FileWriter("." + ToolKit.fileSeparator() + OUTPUT_FILE_AREA, true)));
 
 Integer total=traffic[0]+traffic[1]+traffic[2]+traffic[3];
                        double greenPercent = ((double)(traffic[0] )) / total*100;
                        double yellowPercent = ((double)(traffic[1]))/total*100;
                        double redPercent = ((double)traffic[2])/total*100;
                        double blackPercent = ((double)traffic[3])/total*100;
 
 
                        outArea.println("Time:" +String.valueOf(sdf.format(now.getTime()))+ " ; " + " Normal " + String.valueOf(greenPercent ) + " % " + " Moderate " + String.valueOf(yellowPercent ) + " % " + " ; " + " Severe " + String.valueOf(redPercent ) + " % " + " ; " + " Unknown " + String.valueOf(redPercent ) + " % ");

Can anybody help me please why the file is empty, what have I done wrong?

Thanks

Does the code close the file after writing to it?

Please edit your post and wrap your code with code tags:
[code=java]
YOUR CODE HERE
[/code]
to get highlighting and preserve formatting.

Can you provide an SSCCE that demonstrates this behavior? Don't forget the highlight tags.

You haven't addressed the points brought up by Norm or Kevin. Do you close the writer, or at the least flush it? The posted code above does not. I recommend, as Kevin did, to post an SSCCE
