Does the getByName() function work on a link with a path like https://stackoverflow.com/questions, or does the link have to include the host only (https://stackoverflow.com)?
I get UnknownHostException when I use a link that contains a "/", any tips on how to resolve that?
The console says the error lies here:
socket = new Socket(InetAddress.getByName(adr), port);
InetAddress.getByName looks up a name (usually in DNS) and returns the corresponding address.
There's no host called "https://stackoverflow.com/questions" so that throws an UnknownHostException.
There's no host called "https://stackoverflow.com" either.
In this particular example, the host name is "stackoverflow.com".
If you want to parse a URL (such as "https://stackoverflow.com/questions") to get the hostname, you can use the java.net.URL class:
String hostname = new URL("https://stackoverflow.com/questions").getHost();
System.out.println(hostname); // stackoverflow.com
