here code snapshot of i've done far.

system.setproperty("webdriver.gecko.driver", "c:\\users\\dalakada1\\desktop\\dev\\geckodriver.exe"); system.out.println("1"); desiredcapabilities capabilities = desiredcapabilities.firefox(); system.out.println("2");  capabilities.setcapability("marionette", true); system.out.println("3");  try {     system.out.println("3.5");     //create driver     webdriver driver = new firefoxdriver();     system.out.println("4");
