title: Writing to a temporary file in java
body: <p>I want to write to a temporary file in an append mode. I see that the file is created but the data from the Stringbuffer is not getting written to it. Can somebody tell me why? Please find below the code I have written, </p>
  
  <pre><code>public static void writeToFile(String pFilename, StringBuffer sb)
          throws IOException {
  
      String property = "java.io.tmpdir";
  
  
      String tempDir = System.getProperty(property);
  
      File dir = new File(tempDir);
      File filename = File.createTempFile(pFilename, ".tmp", dir);
      FileWriter fileWriter = new FileWriter(filename.getName(), true);
      System.out.println(filename.getName());
      BufferedWriter bw = new BufferedWriter(fileWriter);
      bw.write(sb.toString());
      bw.close();
  }
  </code></pre>
