Hey Sonal, to get the meta-description of a webpage, you can simply use findElement() and getAttribute() methods in Selenium Webdriver:
System.setProperty("webdriver.chrome.driver", "C:\\Users\\Abha_Rathour\\Downloads\\chromedriver_win32\\chromedriver.exe");
WebDriver driver = new ChromeDriver();
driver.manage().window().maximize();
driver.get("https://www.edureka.co/");
System.out.println(driver.findElement(By.xpath("//meta[@name='description']")).getAttribute("content"));
