Automate accept cookies pop-up fron java app

Java

The app is hoing to load the system default browser, load a special website, and then login automatically (user/password will be given before the app launches).
code:

import java.awt.Desktop;
import java.io.IOException;
import java.net.URI;
import java.net.URISyntaxException;

import org.openqa.selenium.WebDriver;
import org.openqa.selenium.chrome.ChromeDriver;

public class theurl {
    public static void main(String[] args) {
        String url = "http://www.playok.com/en/spades/";
        if(Desktop.isDesktopSupported()){
            Desktop desktop = Desktop.getDesktop();
            try {
                desktop.browse(new URI(url));
            } catch (IOException | URISyntaxException e) {
                e.printStackTrace();
            }
        }else{
            Runtime runtime = Runtime.getRuntime();
            try {
                runtime.exec("xdg-open " + url);
            } catch (IOException e) {
                e.printStackTrace();
            }
        }
    }

but before trying to login, first the cookies should be accepted automatically; is there a simple way to do it rather than using an external library? if not, which library can do the job

What I have tried:

Did try this code, but didnt help:

WebDriver Driver = new ChromeDriver();
Driver.manage().timeouts().implicitlyWait(30, TimeUnit.SECONDS);
String url = "http://www.playok.com/en/spades/";
Driver.get(url);
Driver.findElement(By.id("cookie_action_close_header")).click();
System.out.println("completed");
