you need to import the java net package before you can run this basic example:

try{
      InetAddress ownIP=InetAddress.getLocalHost();
      System.out.println("IP of my Device := "+ownIP.getHostAddress());
      }catch (Exception e){
      System.out.println("Exception caught ="+e.getMessage());
      }

hope it helps, have a nice day
