I want to return false if the URL takes more then 5 seconds to connect – how is this possible using Java? Here is the code I am using to check if the URL is valid
HttpURLConnection.setFollowRedirects(false); HttpURLConnection con = (HttpURLConnection) new URL(url).openConnection(); con.setRequestMethod("HEAD"); return (con.getResponseCode() == HttpURLConnection.HTTP_OK);

HttpURLConnection
has a setConnectTimeout method.
Just set the timeout to 5000 milliseconds, and then catch java.net.SocketTimeoutException
Your code should look something like this:
try {
HttpURLConnection.setFollowRedirects(false);
HttpURLConnection con = (HttpURLConnection) new URL(url).openConnection();
con.setRequestMethod("HEAD");
con.setConnectTimeout(5000); //set timeout to 5 seconds
return (con.getResponseCode() == HttpURLConnection.HTTP_OK);
} catch (java.net.SocketTimeoutException e) {
return false;
} catch (java.io.IOException e) {
return false;
}
