How can I instantiate HTMLUnitDriver?

The HTMLUnitDriver can be instantiated as below:

WebDriver driver = new HtmlUnitDriver(); // Instantiate the class - org.openqa.selenium.htmlunit.HtmlUnitDriver

Sample code:

package tests;

import org.openqa.selenium.WebDriver;
import org.openqa.selenium.htmlunit.HtmlUnitDriver;

public class HTMLUnitDriverSample {
	public static void main(String[] args) {
		// Instantiate the HTMLUnitDriver
		WebDriver driver = new HtmlUnitDriver();

		// Visit the Selenium-WebDriver FAQ site
		driver.get("http://seleniumwebdriverfaq.tumblr.com/");

		// Print the title of the page - It should print"Selenium-WebDriver FAQ's"
		System.out.println("Title of the page is: " + driver.getTitle());

	}
}
