How can I switch WebDriver control to new window?

To switch latest window opened use below code:

for(String winHandle : driver.getWindowHandles()){
    driver.switchTo().window(winHandle);
}

Sampe code:

 package test;

import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.firefox.FirefoxDriver;

public class SwithcToNewWindow {

	public static void main(String[] arg) {

		// Instantiate the FirefoxDriver
		WebDriver driver = new FirefoxDriver();

		// Visit the Selenium-WebDriver FAQ site
		driver.get("http://seleniumwebdriverfaq.tumblr.com/");

		// Print the title of the page - It should print
		// "Selenium-WebDriver FAQ's"
		System.out.println("Title of the page before - switchingTo: " + driver.getTitle());

		//Now click on RSS button; it will open in new window
		driver.findElement(By.xpath("//a[text()='RSS']")).click();

		//Switch to newly opened window -RSS and get the page titele
		for(String winHandle : driver.getWindowHandles()){
		    driver.switchTo().window(winHandle);
		}
		System.out.println("Title of the page after - switchingTo: " + driver.getTitle());

		// Close the browser window
		driver.close();

		// Quit the driver
		driver.quit();
	}
}
