testing - How to switch between two windows in browser using Selenium java

Question

I'm working with Selenium Automation. In this, When i click a link in a current window, a new window opens. I just want to switch the control to the new window. But i can't do this.Actually the new window is an auto-generated one. That is, link will be generated dynamically. Help me friends...

To switch between windows we have method.

driver.switchTo().window("window name") 

To get the different windows handle, we have method.

driver.getWindowHandles()

Example:

    File file = new File("G:\Selenium\All_Jars\chromedriver.exe");
    System.setProperty("webdriver.chrome.driver",file.getAbsolutePath() );
    driver = new ChromeDriver();

    //Maximize the window
    driver.manage().window().maximize();

    driver.get("http://www.rediff.com/");

    //Get all window handles
    Set<String> allHandles = driver.getWindowHandles();

    //count the handles Here count is=2
    System.out.println("Count of windows:"+allHandles.size());      

    //Get current handle or default handle
    String currentWindowHandle = allHandles.iterator().next();
    System.out.println("currentWindow Handle"+currentWindowHandle);

    //Remove first/default Handle
    allHandles.remove(allHandles.iterator().next());

    //get the last Window Handle
    String lastHandle = allHandles.iterator().next();
    System.out.println("last window handle"+lastHandle);

    //switch to second/last window, because we know there are only two windows 1-parent window 2-other window(ad window)
driver.switchTo().window(lastHandle);
    System.out.println(driver.getTitle());
    driver.findElement(By.tagName("body")).click();
