Failed to start Firefox browser from Selenium Webdriver version 3.4.0

Question

I had a problem with the fact that I cannot start firefox from Selenium Webdriver version 3.4.0 from my Windows operating system (Windows 7), which is 64-bit. Currently, firefox version 52.0.2 is installed on my machine. I also added the selenium jar library files to the library, but an error appears.

My code is:

package sanity;

import org.openqa.selenium.WebDriver;
import org.openqa.selenium.firefox.FirefoxDriver;

public class Login
{
        public static void main(String[] args)    
        {
            WebDriver driver=new FirefoxDriver();    
            driver.close(); 
        }
}

Error:

Exception in thread "main" java.lang.IllegalStateException: The path to the driver executable must be set by the webdriver.gecko.driver system property; for more information, see https://github.com/mozilla/geckodriver. The latest version can be downloaded from https://github.com/mozilla/geckodriver/releases

    at org.openqa.selenium.firefox.FirefoxDriver.<init>(FirefoxDriver.java:104)
    at sanity.Login.main(Login.java:18)

After that, I loaded the GeckoDriverService into the SeleniumHQ.org form and started under the code, now after starting under the updated code using the Geckodriver path, the Firefox browser starts, but does not close automatically. I also get a message in the console.

The code:

package sanity;

import org.openqa.selenium.WebDriver;
import org.openqa.selenium.firefox.FirefoxDriver;

public class Login 
{

        public static void main(String[] args) 
        {

          String Firefoxdriverpath="C://Users//Ashish//Downloads//geckodriver-v0.16.0-win64//geckodriver.exe";

            System.setProperty("webdriver.gecko.driver", Firefoxdriverpath);

            WebDriver driver=new FirefoxDriver();

            driver.close(); 
        }

}

Console:
