@SuppressWarnings("unused")
public class OpenGoogle {
    
public static void main(String [] arg)

//set the path of the chrome driver exe file

System.setProperty("webdriver.chrome.driver", "C:\\Selenuim\\chromedriver2.8.exe");

//create the new instance of the chrome browser
WebDriver driver =  new ChromeDriver();


try{

//set the implicit and page load time outs  

driver.manage().timeouts().implicitlyWait(5, TimeUnit.SECONDS);
driver.manage().timeouts().pageLoadTimeout(50,TimeUnit.SECONDS);

//navigate to given url
driver.get("https://www.google.co.in/preferences");

//Maximize the browser window
driver.manage().window().maximize();

//find the element on which you want to mouse hover
WebElement e =  driver.findElement(By.xpath("//*[@id='Trade_Summary1_1']/table/thead/tr"));

//we can perform complex operations like mouse over using Actions class 
 Actions builder = new Actions(driver);
 Action hoverAction = builder.moveToElement(e).build();

//perform the mouse over action in selenium webdriver
 hoverAction.perform();


Thread.sleep(2000);

}

catch(Exception e){
 System.out.println("Exception - > " + e.toString());
 }
 finally{
  driver.close();
  driver.quit();
