          // USE OF CHROME Driver constructor ChromeDriver(service, options)
 public static void ChromeLocalDriver02(WebDriver driver) {
  System.setProperty("webdriver.chrome.driver", "C:\\Java_Source_Code\\chromedriver_win32\\chromedriver.exe");
  // setting up the service
  ChromeDriverService.Builder builder = new ChromeDriverService.Builder();
  ChromeDriverService service = builder.withLogFile(new File("C:\\Test\\ie_log\\chrome1.log")).build();
  // chrome options
  ChromeOptions options = new ChromeOptions();
  // Opening Chrome browser with current default profile
  options.addArguments("user-data-dir=C:\\Users\\sudas\\AppData\\Local\\Google\\Chrome\\User Data\\sudas");
  // this is to start Chrome windows as maximized
  options.addArguments("start-maximized");
