In automation, when we have different windows in any web application, the action may need to switch control among a few windows from one to other with a specific end goal to finish the task. After consummation of the activity, it needs to come back to the principle window i.e. parent window.

In selenium web driver there are strategies through which we can deal with numerous windows.

Driver.getWindowHandles();

To manage each and every opened window by web driver, we can use "Driver.getWindowHandles()" and after that we can change window beginning with one window then onto the following in a web application. Its landing compose is Iterator<String>.

Driver.getWindowHandle();

At the point when the site opens, we have to deal with the principle window by driver.getWindowHandle(). This will deal with the ebb and flow window that exceptionally distinguishes it inside this driver case. Its arrival write is String.
