how to create a simple automation ith selinium code example

Example: running Seleniam tests

// Sample test in Java to run Automate session.
import org.openqa.selenium.By;
import org.openqa.selenium.Platform;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.remote.DesiredCapabilities;
import org.openqa.selenium.remote.RemoteWebDriver;
import java.net.URL;
public class JavaSample {
  public static final String AUTOMATE_USERNAME = "YOUR_USERNAME";
  public static final String AUTOMATE_ACCESS_KEY = "YOUR_ACCESS_KEY";
  public static final String URL = "https://" + AUTOMATE_USERNAME + ":" + AUTOMATE_ACCESS_KEY + "@hub-cloud.browserstack.com/wd/hub";
  public static void main(String[] args) throws Exception {
    DesiredCapabilities caps = new DesiredCapabilities();
    caps.setCapability("os_version", "8");
    caps.setCapability("resolution", "1920x1080");
    caps.setCapability("browser", "Chrome");
    caps.setCapability("browser_version", "latest-beta");
    caps.setCapability("os", "Windows");
    caps.setCapability("name", "BStack-[Java] Sample Test"); // test name
    caps.setCapability("build", "BStack Build Number 1"); // CI/CD job or build name
    WebDriver driver = new RemoteWebDriver(new URL(URL), caps);
    driver.get("https://www.google.com");
    WebElement element = driver.findElement(By.name("q"));
    element.sendKeys("BrowserStack");
    element.submit();
    System.out.println(driver.getTitle());
    driver.quit();
  }
