Scroll down method in WebDriver

Here i am adding simple code for Scroll down method.we can scroll down and up methods in a 3 ways....

Using JavaScriptExecutor:

  JavascriptExecutor jsx = (JavascriptExecutor)driver;

  jsx.executeScript("window.scrollBy(0,450)", "");

 

 Using Actions Class

Actions action=new Actions(driver);

       action.sendKeys(Keys.DOWN).perform();

       action.sendKeys(Keys.DOWN).perform();

       action.sendKeys(Keys.DOWN).perform();

       action.sendKeys(Keys.DOWN).perform();

     

   {OR}

Actions action=new Actions(driver);

                  action.keyDown(Keys.CONTROL).sendKeys(Keys.PAGE_DOWN).perform();

   {OR}

With out Using Actions Class

 for(int i=0;i<20;i++)

                    {

                             driver.findElement(By.tagName("body")).sendKeys(Keys.DOWN);

                    }
