Selenium WebDriver using JavaScript - selenium-webdriver

Question

I'm new to Selenium WebDriver and trying to automate the online shopping site "amazon.co.uk". My intention is to navigate to a particular page of the site and retrieve the sellers names,their respective URL's and write the final output to an Excel Sheet. I was able to print all the above mentioned details in the console but couldn't write them into an Excel Sheet.
Below is the piece of code that I had come up with:
package Selenium.src.com.amazon.automation;
import java.io.IOException;
import java.util.List;
import java.util.concurrent.TimeUnit;
import org.openqa.selenium.By;
import org.openqa.selenium.JavascriptExecutor;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.firefox.FirefoxDriver;
import org.openqa.selenium.interactions.Actions;
public class AmazonTest {
public static void main(String[] args) throws InterruptedException, IOException {
WebDriver driver = new FirefoxDriver();
try {
driver.get("https://www.amazon.co.uk");
Thread.sleep(1000);;
driver.manage().window().maximize();
driver.manage().timeouts().implicitlyWait(150, TimeUnit.SECONDS);
String PageTitle = driver.getTitle();
System.out.println("Page Title is :" + PageTitle );
} catch (Exception e) {
e.printStackTrace();
System.out.println("Driver not reachable");
}
WebElement wb = driver.findElement(By.xpath("//span[text()='Shop by']"));
WebElement wb1 = driver.findElement(By.xpath("//span[text()='Electronics & Computers']"));
Actions act = new Actions(driver);
act.moveToElement(wb).build().perform();
act.moveToElement(wb1).build().perform();
driver.findElement(By.xpath("//span[text()='Headphones']")).click();
Thread.sleep(2000);
// To wait until the next page loads
driver.manage().timeouts().implicitlyWait(20, TimeUnit.SECONDS);
JavascriptExecutor jse = (JavascriptExecutor)driver;
jse.executeScript("scroll(0, 1000);");
driver.findElement(By.xpath("(//span[text()='See more'])[2]")).click();
List<WebElement> topSellers = driver.findElements(By.xpath("//div[#id='refinementList']//a"));
// int sellersCount = topSellers.size();
System.out.println("The Number Of Top Sellers is :" + topSellers.size());
for(int i=0;i<topSellers.size();i++)
{
//To print the list of Top Sellers and their number of products
System.out.println(topSellers.get(i).getText());
//To print the link of individual seller
System.out.println(topSellers.get(i).getAttribute("href"));
/*To get the page title for individual seller
String PageTitle = driver.getTitle();
System.out.println("Page Tile for this seller is :" +PageTitle);
topSellers.get(i).click();
Thread.sleep(2000);
driver.navigate().back();
WebDriverWait wait = new WebDriverWait(driver,20);
wait.until(ExpectedConditions.titleIs("Amazon.co.uk: see all sellers"));
driver.navigate().refresh();*/
}
driver.close();
}
}
Can anybody please help me to achieve this requirement
I'm trying to write the below mentioned data into the Excel sheet...
1. Seller Name
2. Number of products of the seller
3. href link for individual seller
Please find the Screenshot for the same.
Image shows the list of TopSellers and the count of their products
