Java: Writing content to file gets over written after all lines are written

I am trying to write text content into a file using Java.

I am using a loop that wraps the following code:

Note: urlForAllStores is a String object.

FileWriter fw = new FileWriter(Play.getFile(SHOPS_FILE),true); 
//the true will append the new data

    fw.write(urlForAllStores+System.getProperty("line.separator"));
    //appends the string to the file
    fw.close();

It works fine, but then when my loop finishes all the content is deleted, and I lose all the results.

Is there anything in here that suggests that would happen, or is it likely to be in some other part of the code.

I have a file at /home/charlie/file.txt, containing Hey

$ cat /home/charlie/file.txt

gives

Hey

After running this code

    try {
        FileWriter fw=new FileWriter(new File("/home/charlie/file.txt"), true);
        fw.write("This is written by Java \n");
        fw.close();
    } catch (IOException e) {
        e.printStackTrace();
    }

(Because I don't have the class Play, you should give that in your post)

And this command

$ cat /home/charlie/file.txt

My new output is

Hey
This is written by Java

So I can't reproduce your problem to find what's wrong.

Please let me know whether it works or not
Happy coding :) -Charlie
