Example

import java.util.concurrent.TimeUnit; 
import org.openqa.selenium.WebDriver; 
import org.openqa.selenium.firefox.FirefoxDriver;
 
public class BrowserCommands {
 
public static void main(String[] args) throws InterruptedException {
 
// Create a new instance of the Firefox driver 
WebDriver driver  driver = new FirefoxDriver();
 
//Put a Implicit wait, this means that any search for elements on the page could take the time the implicit wait is set for before throwing exception 
driver.manage().timeouts().implicitlyWait(10, TimeUnit.SECONDS);
 
//Launch the Google Website 
driver.get("http://www.google.com");
 
// Storing Title name in String variable 
String sTitle = driver.getTitle();
 
// Storing Title length in Int variable 
int iTitleLength = driver.getTitle().length();
 
// Printing Title name on Console 
System.out.println(sTitle);
 
// Printing Title length on console 
System.out.println(iTitleLength);
 
// Storing URL in String variable 
sTitle = driver.getCurrentUrl();
 
// Storing URL length in Int variable 
iTitleLength = driver.getCurrentUrl().length();
 
// Printing URL on Console 
System.out.println(sTitle);
 
// Printing URL length on console 
System.out.println(iTitleLength);
 
// Refreshing current page 
driver.get(driver.getCurrentUrl());  
 
// Storing Page Source in String variable 
String sPageSource = driver.getPageSource();
 
// Storing Page Source length in Int variable 
int iPageSourceLength = driver.getPageSource().length();
 
// Printing Page Source on console 
System.out.println(sPageSource);
 
// Printing Page SOurce length on console 
System.out.println(iPageSourceLength);
 
//Closing browser 
driver.close();

How to operate browser Cookies in Selenium Webdriver using java.

cookie: An HTTP cookie (also called web cookie, Internet cookie, browser cookie or simply cookie, the latter which is not to be confused with the literal definition), is a small piece of data sent from a website and stored in a user's web browser while the user is browsing that website.
We can perform required task with respect to browser cookies in Selenium Webdriver and can add , delete, delete particular cookie by passing the name.

Add Cookie
Method Name: addCookie(Cookie cookie)
Syntax: driver.manage().addCookie(arg0);
Description: 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.
Example:
Cookie name = new Cookie("firefoxcookie", "123456789123");
driver.manage().addCookie(name);

Get the Cookie with Specific Name
Method Name: getCookieNamed(java.lang.String name)
Syntax: driver.manage().getCookieNamed(arg0);
Description: To Get a cookie with a given name.
Example:
driver.manage().getCookieNamed("firefoxcookie");

Get Cookies
Method Name: getCookies()
Syntax: driver.manage().getCookies();
Description: Get all the cookies for the current domain.
Example:
Set<Cookie> cookiesList1 = driver.manage().getCookies();
for (Cookie getcookies : cookiesList1) {
System.out.println(getcookies);
}

Delete Cookie with Name
Method Name: deleteCookieNamed(java.lang.String name)
Syntax: driver.manage().deleteCookieNamed(arg0);
Description: Delete the named cookie from the current domain.
Example:
driver.manage().deleteCookieNamed("firefoxcookie");

Delete All Cookies
Method Name: deleteAllCookies()
Syntax: driver.manage().deleteAllCookies();
Description: It will delete all the cookies for the current domain.
Example:
driver.manage().deleteAllCookies();

Full Example

import java.util.Set;
import java.util.concurrent.TimeUnit;
import org.openqa.selenium.Cookie;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.firefox.FirefoxDriver;


public class Handlecookie {

public static void main(String args[]) {

//Go to desire wbesite      
driver.get("http://www.google.com");
//Set  timeout      
driver.manage().timeouts().implicitlyWait(10, TimeUnit.SECONDS);

//pass name and value for cookie as parameters
Cookie name = new Cookie("firefoxcookie", "123456789123");
// Add Cookie
driver.manage().addCookie(name);

// Get the Cookie with Specific Name     
System.out.println(driver.manage().getCookieNamed("firefoxcookie"));


System.out.println("=======================================");
//Get all Cookies
Set<Cookie> cookiesList1 = driver.manage().getCookies();
for (Cookie getcookies : cookiesList1) {
    System.out.println(getcookies);
}
System.out.println("=======================================");


// Delete Cookie with Name    
driver.manage().deleteCookieNamed("firefoxcookie");

System.out.println("=======================================");
//Check deleted or not firefoxcookie Cookie 
Set<Cookie> cookiesList2 = driver.manage().getCookies();
for (Cookie getcookies : cookiesList2) {
    if (getcookies.getName().equals("firefoxcookie")) {
System.out.println(driver.manage().getCookieNamed("firefoxcookie"));
    } else {
System.out.println("There is no cookies name firefoxcookie");
break;
    }

}

System.out.println("=======================================");



//Delete all the cookies of the domain
driver.manage().deleteAllCookies();

// Check all the cookies deleted or not
Set<Cookie> cookiesList3 = driver.manage().getCookies();
if (cookiesList3.size() == 0) {
    System.out.println("There are no cookies");
}

//close firefox browser  
driver.quit();
    }
