Re: Writing to a file

Thanks so much for the help.

That did the trick - I am sure the other sample sent in would work as
well. Now my question is which way is better of the following two
methodologies: (most code snipped for brevity)

1) ** USING BUFFERED WRITER - EXAMPLE FROM JAVA.SUN.COM FOR Java 1.2 **

File fileOut = new File("/space/users/swd/java/testFile.txt");
BufferedWriter out = new BufferedWriter(new FileWriter(fileOut));
out.write("we are writting to a file ");
out.close();

2) ** USE FILEWRITER AS I ORIGINALLY POSTED WITH HELP FROM ABOVE **

File fileOut = new File("/space/users/swd/java/testFile.txt");
FileWriter fw = new FileWriter(fileOut);
fw.write("docHeader\n");
fw.close();

IOW should I use the BufferedWriter wrapper or not?

Gotcha.

Thanks again,
Jon
