How to fetch last row of a webtable in selenium - selenium

Question

I have a webtable for which I have to fetch the last row . The problem is that the webtable is dynamic so I don't know the row number.I have tried below code but the row number is static there which will fail.
List<WebElement> rows=driver.findElements(By.xpath("//table[1]/tbody/tr[5]"));

Answer 1

to get last element use (locator)[last()] method, like:
WebElement lastRow = driver.findElement(By.xpath("(//table[1]/tbody/tr)[last()]"));
which is shorted variant of:
(locator)[position() = last()]

Answer 2

public class LastRowFetching {
public static void main(String[] args) throws ParseException {
WebDriver driver;
System.setProperty("webdriver.chrome.driver","G://chromedriver.exe");
driver= new ChromeDriver();
driver.get("http://money.rediff.com/gainers/bsc/dailygroupa?");
//No.of rows
List rows = driver.findElements(By.xpath(".//*[#id='leftcontainer']/table/tbody/tr/td[1]"));
System.out.println("No of rows are : " + rows.size());
int lastRow = rows.size();
WebElement lastRowFetch =driver.findElement(By.xpath(".//*[#id='leftcontainer']/table/tbody/tr/td["+lastRowcount+"])"));
driver.close();
}
}

Answer 3

int lastRowcount=driver.findElement(By.xpath("//table[1]/tbody/")).findElements(By.tagName("tr")).size();
WebElement Lastrow =driver.findElement(By.xpath("//table[1]/tbody/tr["+lastRowcount+"]"));
In first Line we get the Last Row count from the table.
On second line we get the Last row Element from the table.
