How to validate a link showing 500 error in Selenium? - selenium

Question

I am trying to validate the links of a website using server response code and page title, the server response found through the code shown below is 200 and page title is also same for all the pages.
the code is as follows:
if(url == null || url.isEmpty())
{
System.out.println("URL is either not configured for anchor tag or it is
empty");
objExcelFile.writeExcel(filePath,"skipped_links",url);
}
else if(!url.startsWith(homePage)){
System.out.println("URL belongs to another domain, skipping it.");
objExcelFile.writeExcel(filePath,"skipped_links",url);
}
else{
try {
huc = (HttpURLConnection)(new URL(url).openConnection());
huc.setRequestMethod("HEAD");
huc.connect();
respCode = huc.getResponseCode();
if(respCode != 200){
System.out.println(url+" is a broken link");
String Actualtitle = driver.getTitle();
System.out.println(Actualtitle);
System.out.println(respCode);
objExcelFile.writeExcel(filePath,"broken_links",url);
}
else{
String Actualtitle = driver.getTitle();
System.out.println(Actualtitle);
if (Actualtitle.contentEquals(unexpectedTitle)){
System.out.println(url+ " is a broken link");
objExcelFile.writeExcel(filePath,"broken_links",url);
} else {
System.out.println(url+ " is a valid link");
System.out.println(respCode);
objExcelFile.writeExcel(filePath,"valid_links",url);
}
}
} catch (MalformedURLException e) {
e.printStackTrace();
}
The header is intact but the link is showing 500 error below the header. The issue is that even though page is showing 500 error, I am getting the server response code as 200, hence I am not able to make out whether this link is broken or not
This is the screenshot of the issue for the page I am validating :

Once you induce connect() as in :
huc.connect();
You can write as many for() loops to check any condition of the Response Code invoking getResponseCode() method as below :
if (huc.getResponseCode() == 200)
{
System.out.println(linkURL + " - " + httpUrlConnect.getResponseMessage());
}
if (huc.getResponseCode() == 500)
{
System.out.println(linkURL + " - " + httpUrlConnect.getResponseMessage());
}
if (huc.getResponseCode() == 404)
{
System.out.println(linkURL + " - " + httpUrlConnect.getResponseMessage());
}
if (huc.getResponseCode() == 402)
{
System.out.println(linkURL + " - " + httpUrlConnect.getResponseMessage());
}
if (huc.getResponseCode() == httpUrlConnect.HTTP_NOT_FOUND)
{
System.out.println(
linkURL + " - " + huc.getResponseMessage() + " - " + huc.HTTP_NOT_FOUND);
}
} catch (IOException e)
{
System.out.println(e.getMessage());
}
