im not getting the output........

If it's not a problem, can you show me the text you're trying to edit?
Also, try the djl1900's suggestion

Its just i was doing a similar program last night and was getting a FileNotFound exception, until i pointed to the exact location of the file.

Good observation, that might be the problem. Just a tip... If i remember correctly, if you're writing a file, if the file doesn't exist in the directory, it will be created. When specifiying only the file's name, the directory will be the folder in which your project is located.

try

  outWriter.write("I like bananas");
  //To close
  outWriter.flush();
  outWriter.close();
}catch(IOException e)
{
  e.printStackTrace();
  return;
}

can you explain why you think a PrintWriter is worse than a FileWriter?

here are the API's...


FileWriter

BufferedWriter

PrintWriter

For what its worth two of those API links are to version 1.4 - which is almost 10 years old. The current release is v1.7, so I encourage those pointing to API's, please point towards a more recent versions (at this time versions 1.6 or 1.7)
