    public static void main(String[] args)
    {
        // The string to be written in the writer
        String str = "GeeksForGeeks";

            // Write the above string to this writer
            // This will put the string in the writer
            // till it is printed on the console
            writer.write(str);

            System.out.println(writer.toString());

            // Now clear the writer
