You are creating an instance of ChromeDriver before setting the property. Can you try after making following changes:
public class Login
{
static WebDriver driver;
#SuppressWarnings("resource")
public static void main(String[] args) throws InterruptedException
{
System.setProperty("webdriver.chrome.driver","C:\\Users\\MMFD-3\\MYData\\chromedriver.exe");
driver = new ChromeDriver();
String baseUrl = "https://stackoverflow.com/";
driver.get(baseUrl);
}
}
And make sure the chrome driver version is matching with your chrome version

This error message...
Exception in thread "main" java.lang.ExceptionInInitializerError Caused by: java.lang.IllegalStateException: The path to the driver executable must be set by the webdriver.chrome.driver system property; for more information, see https://github.com/SeleniumHQ/selenium/wiki/ChromeDriver.
...implies that your program was unable to locate the chromedriver excutable.
Seems you were pretty close. Within the class defination, you can of coarse declare the WebDriver instance as follows:
static WebDriver driver;
But you mustn't instantiate it as you did:
static WebDriver driver = new ChromeDriver();
Unless you specifically mention the absolute path of the chromedriver executable.
Solution
You need to separate the initialization part from the declaration:
static WebDriver driver;
Initialize the webdriver as a instance of ChromeDriver() later as follows:
System.setProperty("webdriver.chrome.driver","C:\\Users\\MMFD-3\\MYData\\chromedriver.exe");
String baseUrl = "https://stackoverflow.com/";
driver = new ChromeDriver();
driver.get(baseUrl);

Selenium session not created exception error

I am getting this error:
"Exception in thread "main" org.openqa.selenium.SessionNotCreatedException: session not created exception"
i have updated my chrome and driver also to latest version.but still getting same error.
package helloworld;
public class testfb {
public static void main(String[] args) {
System.setProperty("webDriver.ChromeDriver", "C:\\minal\\drivers\\ChromeDriver.exe ");
// TODO Auto-generated method stub
WebDriver driver = new ChromeDriver();
driver.get("https://www.google.com/");
}
}

chrome driver system property is case sensitive.
use this:
System.setProperty("webdriver.chrome.driver", "/path/to/chromedriver");

Firefox browser is not opening in Selenium webdriver in eclipse

I'm using Firefox 45.8.0 version and I tried below code to open Firefox browser but i'm getting error that: "The path to the driver executable must be set by the webdriver.gecko.driver system property".
Please sagest me how to set the path.
Note:gecko driver will work for above firefox version 48.
package First;
import org.openqa.selenium.firefox.FirefoxDriver;
public class City {
public static void main(String[] args) {
// TODO Auto-generated method stub
FirefoxDriver c1=new FirefoxDriver();
c1.get("http://google.com");
}
}

Try this below code.
In your code you were not provide gecko driver path. You can download gecko driver from this link
public class City {
public static void main(String[] args) {
System.setProperty("webdriver.gecko.driver", "C:\\Drivers\\geckodriver.exe");
WebDriver driver = new FirefoxDriver();
driver.manage().window().maximize();
driver.manage().timeouts().implicitlyWait(25, TimeUnit.SECONDS);
driver.get("http://google.com");
}
}

Browser not opening using Selenium webdriver

Here is the error:
[11762:11762:0801/141204:ERROR:url_pattern_set.cc(240)] Invalid url
pattern: chrome://print/*
getrlimit(RLIMIT_NOFILE) failed
[11762:11886:0801/141205:ERROR:get_updates_processor.cc(243)] PostClientToServerMessage() failed during GetUpdates
getrlimit(RLIMIT_NOFILE) failed
Code :
public class FirstTestCase {
public static void main(String[] args) throws InterruptedException {
// TODO Auto-generated method stub
System.setProperty("webdriver.chrome.driver", "/usr/bin/google-chrome");
WebDriver driver = new ChromeDriver();
String URL = "mail.google.com";;

There are two problem in your provided code :-
You are setting webdriver.chrome.driver with installed chrome location which wrong. you need to download latest chrome driver zip from here and put at any location in your machine and extract that zip and set found chromedriver to the system property with variable webdriver.chrome.driver.
You are providing wrong URL to launch, You should provide URL with http:// or https://.
So the working example are as below :-
public class FirstTestCase {
public static void main(String[] args) throws InterruptedException {
System.setProperty("webdriver.chrome.driver", "path/to/downloaded chromedriver");
WebDriver driver = new ChromeDriver();
String URL = "https://www.google.com";
driver.get(URL);
}
}
Hope it works..:)
