 driver executable must be set by the webdriver.chrome.driver 
 system property;

Below is the code of 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.driverinsteadwebdriver.chromedriver.driver

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

Must 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 only work if you first set the system property and then create the chrome driver ..
