Answer 1

Just updated your code. You will have to set driver path while setProperty and user webdriver.gecko.driver for latest firefox driver.

    if (browsers.equalsIgnoreCase("Firefox")) {
            String driverPath = System.getProperty("user.dir") + "\\src\\test\\java\\drivers\\geckodriver.exe"; 
            System.setProperty("webdriver.firefox.driver", "driverPath"); 
            DesiredCapabilities capabilities = new DesiredCapabilities();
            capabilities.setCapability("marionette", false); 
            FirefoxOptions options = new FirefoxOptions(); 
            options.merge(capabilities);
            FirefoxDriver driver = new FirefoxDriver(options);
            driver.manage().timeouts().implicitlyWait(30, TimeUnit.SECONDS);
        } 
        else if (browsers.equalsIgnoreCase("Chrome")) {
            // String driverPath = System.getProperty("user.dir") +
            // "\\src\\Drivers\\chromedriver";
            // System.setProperty("webdriver.chrome.driver", driverPath);
            System.setProperty("webdriver.chrome.driver", "D:\\chromedriver.exe");
            driver = new ChromeDriver();
            driver.manage().timeouts().implicitlyWait(30, TimeUnit.SECONDS);
        }

Let me know.
