在Selenium和Java中无法从按索引的下拉列表中进行选择

import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.chrome.ChromeDriver;
import org.openqa.selenium.support.ui.Select;

WebDriver driver = new ChromeDriver();

WebElement dropdown = driver.findElement(By.id("dropdownId"));
Select select = new Select(dropdown);

select.selectByIndex(index);

import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.chrome.ChromeDriver;
import org.openqa.selenium.support.ui.Select;

public class DropdownExample {
    public static void main(String[] args) {
        WebDriver driver = new ChromeDriver();
        driver.get("https://example.com");

        WebElement dropdown = driver.findElement(By.id("dropdownId"));
        Select select = new Select(dropdown);

        int index = 2; // 选择第三个选项
        select.selectByIndex(index);

        driver.quit();
    }
}
