public class set_forWindow {

static WebDriver driver;

public static void main(String[] args) {
//pop up window code for Firefox ----- working fine.
//driver=new FirefoxDriver();

//pop up window code to test on cromedriver.
/*System.setProperty("webdriver.chrome.driver", "C:\\selenium-2.48.2\\OthersDriver\\chromedriver.exe");
driver=new ChromeDriver();*/

//pop up window code in IE
System.setProperty("webdriver.ie.driver", "C:\\selenium-2.48.2\\IEWebDriver\\IEDriverServer.exe");
driver=new InternetExplorerDriver();


driver.manage().window().maximize();
driver.manage().timeouts().implicitlyWait(20000, TimeUnit.MILLISECONDS);
driver.manage().timeouts().pageLoadTimeout(10, TimeUnit.SECONDS);

Set<String> windowIds=driver.getWindowHandles();
System.out.println("Total no of Windows: " + windowIds.size());
Iterator<String> windowIt=windowIds.iterator();
while(windowIt.hasNext())
{
System.out.println("Window id : " + windowIt.next());
}
System.out.println("----------------------------------------");
driver.get("http://in.rediff.com");
windowIds=driver.getWindowHandles();
System.out.println("Total no of Windows: " + windowIds.size());
windowIt=windowIds.iterator();
/*while(windowIt.hasNext())
{
System.out.println("Window id : " + windowIt.next());
}*/
String parentWindowId=windowIt.next();
String popWindowId=windowIt.next();
driver.switchTo().window(popWindowId);
driver.switchTo().activeElement(); // code is must for IE
driver.close();
driver.switchTo().window(parentWindowId);
