Reg PrintWriter

[babu sharath]

Hi ,
I am using java1.4
I write following code.
Problem is : In the end new file is created , but it is empty nothing is written
in that file . Why ? line1 and line2 should be placed in the file , why it is not happening ?

import java.io.*;
class Test
{
public static void main(String args[])
{
try {
File f = new File("test12.txt");
if(!f.exists())
f.createNewFile();
FileWriter fw = new FileWriter(f);
PrintWriter pw = new PrintWriter(fw);
pw.println("line1");
pw.println("line2");
}
catch (Exception e)
{
e.printStackTrace();
}
}
}

you need to flush() it..

[Dan Polak]

Yeah and close

You need to close FileWriter and PrintWriter than only the content in the file will be commited and than line1 and line2 would be available in the file.

Are we saying here that "close()" method call is mandatory for stuff to be written to file??I dont think so..Its just a best practise..
