Working with Browsers :

1. Open  Firefox Browser :
                                             Webdriver has  FirefoxDriver class to open a new session of firefox browser.
Syntax :
               // Need to import following packages

              import org.openqa.selenium.WebDriver;
              import org.openqa.selenium.firefox.FirefoxDriver;

              //Instance of FirefoxDriver              
               WebDriver ffDriver = new FirefoxDriver();
         
             //Open google.com site
               ffDriver.get("http://www.google.com") ;
  
2. Open Chrome Browser :
                                             Webdriver has ChromeDriver class to open a new session of chrome browser. To use chrome driver we need to download and provide path of ChromeDriver.exe. We can set the path using System.setProperty();
Syntax :
               // Need to import following packages
               import org.openqa.selenium.WebDriver;
               import org.openqa.selenium.chrome.ChromeDriver;

              
              //Instance of ChromeDriver
               System.setProperty("webdriver.chrome.driver", "Path  Of ChromeDriver.exe");
                WebDriver chDriver = new ChromeDriver();
         
             //Open google.com site
               chDriver.get("http://www.google.com") ;

3. Open InternetExplorer Browser :
                                             Webdriver has InternetExplorer class to open a new session of InternetExplorer browser. To use InternetExplorer driver we need to download and provide path of InternetExplorerDriver.exe. We can set the path using System.setProperty();
Syntax :
               // Need to import following packages
               import org.openqa.selenium.WebDriver;
               import org.openqa.selenium.internetexplorer.InternetExplorerDriver;

              
              //Instance of InternetExplorerDriver
               System.setProperty("webdriver.ie.driver", "Path  Of InternetExplorerDriver.exe");
                WebDriver ieDriver = new InternetExplorerDriver();
