i've tried some solutions but nothing worked !, could anyone help please !? Thx.

wait() function call must be called from Synchronized block to avoid this exception.
Do you want to sleep the main thread , if yes please use Thread.sleep() instead of wait() function call.

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

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 }

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();
}
}

This is a known message. See here for more info and discussion.
Bottom line, it's not an error, it won't break anything. If something gets screwed up, then that's when it's a good time to investigate. As it is right now, you can safely ignore it.

You can use the below code with your scripts, which will redirects these low level logs to a separate file rather than the console -
System.setProperty(FirefoxDriver.SystemProperty.DRIVER_USE_MARIONETTE,"true");
System.setProperty(FirefoxDriver.SystemProperty.BROWSER_LOGFILE,"C:\\temp\\logs.txt");

Detected borken kqueue while running the Java code in Selenium

I am getting the following problems with Selenium Test Run. I am using the tests to create and run on macSierra (10.12) Processor 2.8 GHz Intel Core i7.
I have installed Eclipse, Selenium and Java files from Selenium site.
Here is my code :
package com.some.seleniumproject;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.*;
import org.openqa.selenium.WebDriver.*;
import org.openqa.selenium.firefox.*;
public class sampleTest1 {
public static void main (String[] args) {
System.setProperty("webdriver.gecko.driver", "//Library/Java/geckodriver");
WebDriver driver=new FirefoxDriver();
String baseUrl = "http://www.seleniumhq.org";
String et = "Selenium - Web Browser Automation";
driver.get(baseUrl);
String rt = driver.getTitle();
if (rt.contentEquals(et)) {
System.out.println("Title is matched");
}
else {
System.out.println("Title is not matched");
}
driver.close();
}
}
Here are the errors :

However, the above error maybe, correct result is thrown in the output.

Note: This element has neither has attached source nor attached Java doc and hence no Java
doc could be found. - this is for the step driver.close();
Please help.

I've found this bug reported in Mozilla - https://bugzilla.mozilla.org/show_bug.cgi?id=1304266. Read a comment to it.
It looks like libevent issue can cause the problem you've described.
