I am getting unknownhost exception in the following code if the value contains http or https. But it gives result if the url begins with www. 

InetAddress.getByName(value)

Why is it so?

Because http(or https) is the protocol, and not part of the name.

InetAddress.getByName(value) works with names only, not URLs.

  • But then, why do we not get response if we hit api without http or https – A_rmas Jun 23 '16 at 11:14

    When you communicate with a host, you need to know the protocol. However, the `InetAddress` class is only responsible for IP address handling including name resolution, it does not provide a means of communication with the host. – Lucero Jun 23 '16 at 11:16
  • Is there any way to keep http/https dynamically? I got a requirement that use https for registration and login but http for other APIs keeping the base url same! Any solution for this? – A_rmas Jun 24 '16 at 03:48
