getText() and getFirstSelectedOption().getText() not giving the expected text - selenium-chromedriver

Question

I am trying to display all the options of a drop down and then select one option
public class Toolsqa_SelectMenu {
public static void main(String[] args) {
System.setProperty("webdriver.chrome.driver", "E:\\chromedriver.exe");
WebDriver driver = new ChromeDriver();
driver.manage().window().maximize();
driver.manage().timeouts().implicitlyWait(30, TimeUnit.SECONDS);
driver.get("https://demoqa.com/selectmenu/");
WebElement e = driver.findElement(By.xpath("//select[#id='speed']"));
Select s = new Select(e);
System.out.println("First selected item : " + s.getFirstSelectedOption().getText());
List<WebElement> options = s.getOptions();
for(WebElement w : options)
{
System.out.println(" Items in drop down : " + w.getText());
}
s.selectByVisibleText("Faster");
}
}
I am getting
First selected item :
Items in drop down :
Items in drop down :
Items in drop down :
Items in drop down :
Items in drop down :
