Browser refresh in different ways using selenium webdriver

Browser refresh in different ways using selenium web driver:
==============================================

1 1.  Refresh command: Most commonly used and simple command for refreshing a webpage.

Public class RefreshGetCurrentUrl {

       Public static void main(String[] args) throws Interrupted Exception 

{

              WebDriver driver = new FirefoxDriver ();

              driver.manage ().window ().maximize ();

              driver.manage ().deleteAllCookies ();

              driver.manage ().timeouts ().implicitly Wait (30, TimeUnit.SECONDS);

              driver.get ("http://rameshselenium.blogspot.in/");

              Thread. Sleep (2000);

              driver. Navigate ().refresh ();

              Thread. Sleep (2000);

              driver. Quit ();

       }

}

2.SendKeys command: Second most commonly used command for refreshing a webpage. As it is using a send keys method, we must use this on any Text box on a webpage.

public class RefreshSendKeys {

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

              WebDriver driver = new FirefoxDriver();

              driver.manage().window().maximize();

              driver.manage().deleteAllCookies();

              driver.manage().timeouts().implicitlyWait(30, TimeUnit.SECONDS);

              driver.get("http://rameshselenium.blogspot.in/");

              Thread.sleep(2000);

              driver.findElement(By.id("ramesh")).sendKeys(Keys.F5);

               Thread.sleep(2000);

              driver.quit();

       }

}

3.    To command: This command is again using the same above concept. navigate( ).to( ) is feeding with a page url and an argument.

public class RefreshGetCurrentUrl {

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

              WebDriver driver = new FirefoxDriver();

              driver.manage().window().maximize();

              driver.manage().deleteAllCookies();

              driver.manage().timeouts().implicitlyWait(30, TimeUnit.SECONDS);

              driver.get("http://rameshselenium.blogspot.in/");

              Thread.sleep(2000);

       driver.navigate().to(driver.getCurrentUrl());

              Thread.sleep(2000);

              driver.quit();

       }

4.  Get command: This is a tricky one, as it is using another command as an argument to it. If you look carefully, it is just feeding get command with a page url.

public class RefreshGetCurrentUrl {

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

              WebDriver driver = new FirefoxDriver();

              driver.manage().window().maximize();

              driver.manage().deleteAllCookies();

              driver.manage().timeouts().implicitlyWait(30, TimeUnit.SECONDS);

              driver.get("http://rameshselenium.blogspot.in/");

              Thread.sleep(2000);

              driver.get(driver.getCurrentUrl());

              Thread.sleep(2000);

              driver.quit();

       }

}
