Getting java.lang.IllegalStateException even after adding set property webdriver

Question

I am getting Exception:

in thread "main" 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.

Below is the code used SeleniumFirefox.java:

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

 public class SeleniumFirefox {

   public static void main(String[] args) {
    // TODO Auto-generated method stub
    System.setProperty("webdriver.chromedriver.driver",
           "C://Users//balwinder//Desktop//chromedriver.exe");
    WebDriver driver = new ChromeDriver();

/*try {
    Thread.sleep(5000);
} catch(InterruptedException ex) {
    System.out.println(ex.getMessage());
}*/

   }}

Answer 1

set webdriver.chrome.driver instead of webdriver.chromedriver.driver

 System.setProperty("webdriver.chromedriver.driver",
           "C://Users//balwinder//Desktop//chromedriver.exe");

Should be:

System.setProperty("webdriver.chrome.driver",
           "C:\\Users\\balwinder\\Desktop\\chromedriver.exe");

OR

System.setProperty("webdriver.chrome.driver",
           "C:/Users/balwinder/Desktop/chromedriver.exe");

NOTE: it will work only if you are first setting the system property and then instantiating chrome driver..

Answer 2

The PATH to the chromedriver.exe file was not set properly. Download the chrome driver zip file and extract it to a folder, go to the extracted folder, copy the path of that folder by clicking on the PATH tab, and explicitly the write .exe file name (.exe is mandatory to write).

Note: Separator between folders should be \ (backslash)

For example please see below:

System.setProperty("webdriver.chrome.driver", "C:\\Users\\Softwares\\Selenium\\chromedriver_win32\\chromedriver.exe");
