Find Broken Links Using Selenium WebDriver:
One of the key test case is to find broken links on a webpage. Due to existence of broken links, your website reputation gets damaged and there will be a negative impact on your business. It’s mandatory to find and fix all the broken links before release. If a link is not working, we face a message as 404 Page Not Found.
Let’s see some of the HTTP status codes.
Below code fetches all the links of a given website (i.e., SoftwareTestingMaterial.com) using WebDriver commands and reads the status of each href link with the help of HttpURLConnection class.

Given clear explanation in the comments section with in the program itself. Please go through it to understand the flow.
