Google shrinks their css classes etc., so it is not easy to identify everything.
Also you have the problem that you have to "wait" until the site shows the result. I would do it like this:
public static void main(String[] args) {
WebDriver driver = new FirefoxDriver();
driver.get("http://www.google.com");
WebElement element = driver.findElement(By.name("q"));
element.sendKeys("Cheese!\n"); // send also a "\n"
element.submit();
// wait until the google page shows the result
WebElement myDynamicElement = (new WebDriverWait(driver, 10))
.until(ExpectedConditions.presenceOfElementLocated(By.id("resultStats")));
List<WebElement> findElements = driver.findElements(By.xpath("//*[@id='rso']//h3/a"));
// this are all the links you like to visit
for (WebElement webElement : findElements)
{
System.out.println(webElement.getAttribute("href"));
}
}
This will print you:
