Selenium multiple window handling

How to handle multiple window in browser with selenium?

For handling multiple window you have to follow some rules as given below.

String MainWindow=driver.getWindowHandle(); //gives parent window ID only

Set allwindowList = driver.getWindowHandles() //gives a set of windows ID

You should check ID with parent ID by looping over ID and do work as you wish at any page you want.

How to switch window:-
driver.switchTo().window(handle);
For switching window in selenium we use above code.

Program for switching and doing some tast on different window in selenium:-

"package pkg1;

import org.openqa.selenium.JavascriptExecutor;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.chrome.ChromeDriver;

public class MyClass913_multiple_window_handling { 
    public static void main(String[] args) {       
   
        System.setProperty(""webdriver.chrome.driver"",""C:\\Users\\Desk-105\\Documents\\SELENIUM\\chromedriver.exe"");   
        WebDriver driver = new ChromeDriver();   

        /**
     * Open multiple windows.
   */
     
         String pageUrl = ""http://www.google.com"";
   driver.get(pageUrl);
    JavascriptExecutor jsExecutor = (JavascriptExecutor)driver;
    String jsOpenNewWindow = ""window.open('""+pageUrl+""');"";

    for(int i=0;i<6;i++)
    {
     jsExecutor.executeScript(jsOpenNewWindow);
     try {
    Thread.sleep(1000);
   } catch (InterruptedException e) {
    // TODO Auto-generated catch block
    e.printStackTrace();
   }
     System.out.println((i+1)+"" opennd."");
    }
     
 
 
    /**
     * Handle multiple windows.
     */
         String MainWindow=driver.getWindowHandle();
         System.out.println(MainWindow);
         for( String window : driver.getWindowHandles()){
          System.out.println(window);
         }
       
         /**
          * window switching and closing new tabs
          */
         for(String handle : driver.getWindowHandles()) {
             if (!handle.equals(MainWindow)) {
              try {
      Thread.sleep(1000);
     } catch (InterruptedException e) {
      // TODO Auto-generated catch block
      e.printStackTrace();
     }
                 driver.switchTo().window(handle);
                 driver.close();
             }
         }

       
     
    }
}
