Is parameterized constructor (Java) supported in selenium webdriver?

Question

I was asked in an interview whether Selenium Webdriver supported parameterized constructors.

Example:

import java.util.concurrent.TimeUnit;
import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.firefox.FirefoxDriver;
public class Cons {
 public String username="u";
 public String pswd="p";
 public String baseurl="url";
 public WebDriver d;
public Cons(String username, String pswd){
 d = new FirefoxDriver();
 d.manage().timeouts().implicitlyWait(30, TimeUnit.SECONDS);
 d.get(baseurl);
 d.findElement(By.name("username")).sendKeys(this.username);
 d.findElement(By.name("pwd")).sendKeys(this.pswd);
 }
 }

Yes, We can write webdriver code in constructor as well. I tried to create an example with your given code. Hope this helps !

import java.util.concurrent.TimeUnit;
import org.openqa.selenium.By; import org.openqa.selenium.WebDriver; 
import org.openqa.selenium.firefox.FirefoxDriver;
public class Test { 
public String baseurl="http://aavtrain.com/";
public WebDriver d;
public Test(String username, String pswd)
{ 
d = new FirefoxDriver();
d.manage().timeouts().implicitlyWait(30, TimeUnit.SECONDS);
d.get(baseurl); 
d.findElement(By.name("user_name")).sendKeys(username);
d.findElement(By.name("password")).sendKeys(pswd);
}
 public static void main(String aregs[])
 {
 Test t=new Test("abc","cde");
 }
}
