我有以下代码来初始化一个 printwriter 对象——

/* This function is used to initialise the printwriter element so that it can begin the task of writing data into assignor.txt file...
     * 
     */
    public void startwriterassignor(String filename, boolean appendToFile) {

        //pw = null;

        try 
        {

            if (appendToFile== true) 
            {

                    //If the file already exists, start writing at the end of it.
                    pw = new PrintWriter(new FileWriter(filename, true));

            }
            else {

                    pw = new PrintWriter(new FileWriter(filename, false));
                    //  this is equal to:
                    //  pw = new PrintWriter(new FileWriter(filename, false));

            }
            //pw.flush();

        }
        catch (IOException e) {
                e.printStackTrace();
        }

}

首先我使用下面的调用来调用上面的函数——

startwriterassignor("assignor.txt", false);

将一些数据写入文件后，我再次使用下面的调用调用相同的函数-

startwriterassignor("assignor.txt", true);

在第二次调用“startiwriterassignor”之后，更多数据被写入（附加）到文件中。但是新数据没有附加到文件assignor.txt，我该如何纠正这个错误？
