Can you list the key classes used in Selenium for browser automation?

In Selenium for browser automation, the key classes are:

• WebDriver — the main interface for controlling the browser.
• ChromeDriver, FirefoxDriver, EdgeDriver, and others — implementations of WebDriver for specific browsers.
• By — a class for element locators (e.g., By.id, By.xpath).
• WebElement — represents an element on a web page that can be interacted with.
• Actions — for complex user interactions, such as drag-and-drop.
• ExpectedConditions — a set of conditions for explicit waits.

Example of creating a driver and finding an element:

WebDriver driver = new ChromeDriver();
driver.get("https://example.com");
WebElement button = driver.findElement(By.id("submit"));
button.click();
