So, to answer your question - yes, they are different. localhost is given an ip address in the 127.0.0.0 network and given to a virtual loopback network device lo. This device is present on all systems, regardless of whether they have a physical network device fitted (WiFi or Ethernet, for example).
If you are looking a way to do it via Java program then you can also see my post how to find IP address of localhost in Java. If you are working in UNIX network and have lots of machine in LAN (Local Area network), many times you want to know IP address of computers from hostname.
