I was lost. Right, there was no return statement. Below works now
public String getIPAddress(){
String hostip = "";
try {
hostip = InetAddress.getLocalHost().getHostAddress();
System.out.println("ip is "+hostip);
} catch (UnknownHostException e) {
hostip = e.getMessage();
return hostip;
-----It compiles. I wouldn't say it works. If I call a method getIPAddress(), I expect the String I get back to be an IP address. I don't want to have to parse it to determine that it's not an error message. That defeats the whole purpose of the exception mechanism. If that method can't get the IP address, it should throw an exception. In this case, there's no reason to catch the exception; just let it propagate up out of that method.
Beginners often seem to think that exceptions are something that just arose on their own out of the language, and the designers had to add try/catch in order to be able to stop them from preventing our code executing. That's not the case. They were deliberately added to the language as a better way of indicating an error than checking return values at every step.
