If you are using WebDriver 3.3 or higher then you have to download the gecko driver .
This is the link to download the latest geckodriver.exe : Click here to download geckodriver
and then set system properties.
import java.util.concurrent.TimeUnit;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.firefox.FirefoxDriver;
public class Gecko {
public static void main(String[] args) {
System.setProperty("webdriver.gecko.driver", **path to your geckodriver.exe**");
WebDriver driver = new FirefoxDriver();
driver.manage().window().maximize();
driver.manage().timeouts().implicitlyWait(10, TimeUnit.SECONDS);
driver.get("https://www.google.co.in/");
driver.close();
}
}
