Webdriver script won't print to text file

Issue: My Java WebDriver script is creating the text file, printing everything to console properly, but will not print to the said text file. The file is always blank.

My Observation: It's got some to do with how I have written the buffered writer write() and close() functions, but I can't quiet place my finger on it being a noob. All help is highly appreciated.

My Code:

public class WebTableToTxtFile {


        static WebDriver driver = new FirefoxDriver();

        public static void main(String[] args) throws Throwable   {


        driver.navigate().to("http://www.bloomberg.com/markets/stocks/futures");
            driver.manage().window().maximize();
            driver.manage().timeouts().implicitlyWait(20, TimeUnit.SECONDS);

            WebElement table = driver.findElement(By.cssSelector
                    ("div[class='data-tables first']"));

            List<WebElement> irow = table.findElements
                    (By.cssSelector("div[class='data-tables first'] tr"));
            System.out.println("No. of rows in the table are: " + irow.size());

            File txtFile = new File
                ("MyFileLocation/Output.txt");

            for(int r=0; r<irow.size(); r++) {
                WebElement webRow = irow.get(r);
                System.out.print(webRow.getText());

            List<WebElement> allCells = webRow.findElements(By.xpath("th | td"));

                    for(int c=0; c<allCells.size(); c++) {
                        WebElement webCell = allCells.get(c);
                        String text = webCell.getText();
                       System.out.print(text);


                FileWriter fw = new FileWriter(txtFile.getAbsolutePath());
                BufferedWriter bw = new BufferedWriter(fw);


                        bw.write(text);
                        bw.close();

                  }

                    System.out.println("");

                }


            end();      
          }
        public static void end() {
            driver.close();
            driver.quit();
        }
}
