   System.setProperty("webdriver.chrome.driver", "F:\\selenium\\chromedriver.exe");
   System.out.println(System.getProperty("webdriver.chrome.driver"));
   driver = new ChromeDriver();
   
  // driver = new ChromeDriver(DesiredCapabilities.chrome());      driver.manage().timeouts().pageLoadTimeout(60, TimeUnit.SECONDS);
   driver.manage().timeouts().implicitlyWait(10, TimeUnit.SECONDS);
   driver.manage().window().maximize();
   
   try{
      
driver.get("https://www.google.co.in/preferences?hl=en-IN&fg=1");  
driver.findElement(By.xpath("//div[text()='Never show Instant results.']")).click();
driver.findElement(By.xpath("//div[text()='Save']")).click();

driver.get("https://www.google.co.in");       

//String x = driver.switchTo().frame(0).switchTo().frame(0).findElement(By.tagName("h3")).getText();//String x = driver.switchTo().frame(1).findElement(By.tagName("h3")).getText();//String x = driver.switchTo().frame("view").switchTo().frame(0).getPageSource();//System.out.println(x);
String str = "windows 7 How to ";
String d = "";
   
for (int i=1 ;i<=26;i++)
   
{
   char x = (char) (64+i);
   
driver.findElement(By.cssSelector("input[name=q]")).sendKeys(str + x);

Thread.sleep(2000);
List <WebElement> tr =  driver.findElements(By.xpath("//table[@class='gssb_m']//tr"));

for (int co=0 ; co<tr.size();co=co+2)
{
   
   d= d + tr.get(co).getText() + "\r\n";
}

driver.findElement(By.id("lst-ib")).clear();

}

System.out.println(d);
String filePath = "f:\\videos\\"+ str +".txt";
               
               if ((new File(filePath)).exists() )
                  (new File(filePath)).delete();
               
               
               File temp = new File(filePath);
               FileWriter fw = new FileWriter(temp,true);
               fw.append(d);
               fw.close();
               


 

            Thread.sleep(4000);
            //driver.navigate();//driver.navigate("http://www.google.com");      }catch(Exception e){

   //System.out.println(e.getLocalizedMessage());                  e.printStackTrace(new PrintStream(System.out));
         
      }
