How to open incognito/private window with Selenium WD for different browser types?

Question

I want to test my test cases in private window or incognito window.

How to do the same in various browsers:

Answer 1

public class gettext {
  static WebDriver driver= null;

  public static void main(String args[]) throws InterruptedException {

    //for private window

    DesiredCapabilities capabilities = DesiredCapabilities.chrome();
    ChromeOptions option = new ChromeOptions();
    option.addArguments("incognito");
    capabilities.setCapability(ChromeOptions.CAPABILITY,option);
    System.setProperty("webdriver.chrome.driver", "D:\\Tools\\chromedriver.exe");       
    driver= new ChromeDriver(capabilities);

    String url = "https://www.google.com/";
    driver.manage().window().maximize();
    driver.get(url);
    driver.manage().timeouts().implicitlyWait(20,TimeUnit.SECONDS);
    gettextdata();
  } 
}
