Question

This is the code :

import java.io.*;
class tester {
 public static void main(String args[])throws IOException  {
   File f=new File("d:/testerf.txt");
   FileWriter fw=new FileWriter(f,true);
   String s="Working";
   char buffer[]=new char[s.length()];
   s.getChars(0,s.length(),buffer,0);
   fw.write(buffer);
 }
}

The word working is not appended in the file testerf.txt.Nothing happens to the file.
Why the word working is not appended?

Answer 1

You should close the stream: fw.close();
