How to address the log INFO Using `new FirefoxOptions()` is preferred to `DesiredCapabilities.firefox()` in selenium project

Adarsh Kumar :

I just started a selenium project, but things didn't got right, so after searching a bit I found this solution. It works but i can't understand what these red statements want me to do, or how to get rid of them.

import org.openqa.selenium.WebDriver;
import org.openqa.selenium.firefox.FirefoxBinary;
import org.openqa.selenium.firefox.FirefoxDriver;
import org.openqa.selenium.firefox.FirefoxOptions;
import org.openqa.selenium.remote.DesiredCapabilities;
import java.io.*;

public class SelTest1
{
    public  static void main(String [] args)
    {
        System.setProperty("webdriver.gecko.driver","X:\\Gecko\\geckodriver-v0.24.0-win64\\geckodriver.exe");

        File pathBinary = new File("X:\\FireFoxx\\firefox.exe");
        FirefoxBinary firefoxBinary = new FirefoxBinary(pathBinary);
        DesiredCapabilities desired = DesiredCapabilities.firefox();
        FirefoxOptions options = new FirefoxOptions();
        desired.setCapability(FirefoxOptions.FIREFOX_OPTIONS, options.setBinary(firefoxBinary));
        WebDriver obj = new FirefoxDriver(options);

        obj.get("http://www.google.com/");
    }
}

I got the result i wanted, but I don't understand the warning{ red statements}

I am putting those red lines { warnings here too for ease }

DebanjanB :

This INFO log message:

INFO: Using `new FirefoxOptions()` is preferred to `DesiredCapabilities.firefox()`

is the result of the changes incorporated in:

• Selenium v3.0.0-beta4

  Added ability to use FirefoxOptions when starting firefox.
  

• Selenium v3.5.0

  * Start making *Option classes instances of Capabilities. This allows
    the user to do:
  
    `WebDriver driver = new RemoteWebDriver(new InternetExplorerOptions());`
  

---

If your usecase is to explicitly mention the absolute location of the FirefoxBinary you can use the following solution:

• Using FirefoxOptions:

  import org.openqa.selenium.WebDriver;
  import org.openqa.selenium.firefox.FirefoxDriver;
  import org.openqa.selenium.firefox.FirefoxOptions;
  
  public class A_Firefox_binary 
  {
      public static void main(String[] args) 
      {
          System.setProperty("webdriver.gecko.driver", "C:/Utility/BrowserDrivers/geckodriver.exe");
          FirefoxOptions options = new FirefoxOptions();
          options.setBinary("C:\\Program Files\\Mozilla Firefox\\firefox.exe");
          WebDriver driver =  new FirefoxDriver(options);
          driver.get("https://stackoverflow.com");
          System.out.println("Page Title is : "+driver.getTitle());
          driver.quit();
      }
  }
