problem with code

[Ravindra Suroju]

Hi,

I have the code to create a text file and append some data into it and when i run the same program again why is it overwriting the existing file instead of appending the new data... please help me...

import java.io.*;
 
public class writeAFile {
      String path = "C:\\Documents and Settings\\raven\\Desktop\\raven.txt";
      File filepath = new File(path);
      File temp = new File("raven.txt");
 
      public void WriteFile() throws IOException {
        String content = "Test Passed it\tYahoo!!";//
        FileWriter fw = new FileWriter(filepath);
        BufferedWriter br = new BufferedWriter(fw);
        br.append(content);
        br.append('\n');        
        br.append(content);
        br.close();
        fw.close();
      }
 
      public writeAFile() throws IOException {
    try {
      if (temp.createNewFile())
        System.out.println("File created in the directory " + path);
      else
        System.out.println("File could not be created in the directory");
 
      if(temp.canWrite())
        System.out.println("File can be Edited ");
     else
       System.out.println("File cannot be Edited");
    }
    catch (IOException ioe) {
      ioe.printStackTrace();
    }
  }
  public static void main(String[] args) throws IOException {
    writeAFile temp = new writeAFile();
    temp.WriteFile();
  }
}

Looks to me that you are creating a new instance each time the code runs, so instead of opening the file for reading it is writing over it each time.

What I think you need to do is check if the file exsists and if it does not write to it like your code does right now but open it and then append it, I can't give you advice on the code to use as I am new to Java but that seems to be the problem from what I can see, hope that helps.
