How to addcookie with Selenium Webdriver

Using webdriver we can easily pass the cookie to the domain. In order to pass cookie, we should use a method named "addCookie(cookie)"

Method Name: addCookie(Cookie cookie)
Syntax:driver.manage().addCookie(arg0);
Purpose: To add a specific cookie into cookies. If the cookie's domain name is left blank, it is assumed that the cookie is meant for the domain of the current document.
Parameters: cookie - The name and value of the cookie to be add.

@Test
    public void addCookie()
    {
        driver= new FirefoxDriver();
        String URL="http://flipkart.com/";
        driver.navigate().to(URL);
                //we should pass name and value for cookie as parameters
                // In this example we are passing, name=mycookie and value=123456789123
        Cookie name = new Cookie("mycookie", "123456789123");
        driver.manage().addCookie(name);
       
                // After adding the cookie we will check that by displaying all the cookies.
        Set<Cookie> cookiesList =  driver.manage().getCookies();
        for(Cookie getcookies :cookiesList) {
            System.out.println(getcookies );
        }
    }
