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

Question

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/");
    }
}

This image has those red lines

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 }

your example needlessly calls DesiredCapabilities.firefox() ... you never even use it, so just remove that line to get rid of the first info message ...the rest of those can be ignored. — Corey Goldberg, Jul 12 '19 at 14:28
without that, it shows this " Exception in thread "main" org.openqa.selenium.WebDriverException: Cannot find firefox binary in PATH. Make sure firefox is installed. OS appears to be: WIN10" , and I did add the path, and i won't reinstall firefox in it's default location. — Adarsh Kumar, Jul 12 '19 at 15:47

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();
    }
}

Console Output:
