线程“主”中的异常java.lang.ClassCastException：无法将java.util.ArrayList强制转换为org.openqa.selenium.WebElement

Question

I am trying to enter data 'tutorial@gmail.com' at Email field but I'm getting the error mentioned on title/subject.

public static void main(String[] args) {
    WebDriver driver = new FirefoxDriver();
    driver.get("http://www.gmail.com");
    ((WebElement)driver.findElements(By.name("Email"))).sendKeys("tutorial@gmail.com");

Answer 1

findElements returns java.util.List<WebElement> , not WebElement . Maybe you wanted to use findElement (without s ), which returns a single WebElement .

Answer 2

use driver.findElement (it will return single element)

instead of

driver.findElements (It will return list)
