Answer 1

Make sure you have correctly added stand alone jar in your project. You can download it from official site of seleniumhq. java -jar selenium-server-standalone-x.xx.x.jar

Should you have successfully added jar, try the code below:

`

public class Google {

    public static void main(String[] args) throws InterruptedException {
        System.setProperty("webdriver.chrome.driver","***location of your chromedriver.exe***");
        WebDriver driver = new ChromeDriver();
        driver.manage().window().maximize();
        driver.get("https://www.google.com/");
        driver.manage().timeouts().implicitlyWait(10, TimeUnit.SECONDS);
