possible duplicate : Java: How to read a text file

this is my code:

this.fileMetaDataPrintWriter = 
new PrintWriter(new FileOutputStream(new File(fileName), false));

and in other method 

fileMetaDataPrintWriter.write(somedata);

these both methods are called in a thread and the filehandle closed when thread exits.

Still my file is appended and not overwritten.

what is the mistake?

    This code does not append to the file. Either this isn't the real code or you have other code that does append to it. – user207421 Mar 24 '15 at 03:24

I have verified that the following code snippet written directly in main method is overwriting the file contents. Perhaps it is some other interaction in code that is causing a different behavior for you? Test this snippet and verify if overwrite works correctly

PrintWriter fileMetaDataPrintWriter = new PrintWriter(new FileOutputStream(new File("appendtest.txt"), false), true);
fileMetaDataPrintWriter.write("This replaces contents of appendtest.txt");
fileMetaDataPrintWriter.close();

  • The `flush()` is redundant before `close().` – user207421 Mar 24 '15 at 03:49
  • Autoflush has nothing to do with it. `flush()` is *always* redundant before `close().` – user207421 Mar 24 '15 at 22:08
  • I understand, I would normally use `try-with-resources` construct or put the `close()` in a finally block. Auto `flush()` is my choice if I want to tail the file while it's being written – vsnyc Mar 24 '15 at 23:53
