Answer 1

You have to set the web driver. Try below:

System.setProperty("webdriver.gecko.driver", "Path to .exe");

WebDriver driver = new FirefoxDriver();

driver.get("http://seleniumhq.com");

Answer 2

You have to set the geckodriver file in the system property:

System.setProperty("webdriver.gecko.driver","path to geckodriver.exe");

Extract the file geckodriver-v0.16.1-win64.zip and set the path to the geckodriver.exe.

Answer 3

You are not entering path for geckdriver correctly. Extract the file downloaded for geckodriver and set path up to "geckodriver.exe" in extracted folder. Refer this one.

System.setProperty("webdriver.gecko.driver","G:\\Selenium\\Firefox driver\\geckodriver.exe");//set path as per location of your geckodriver
