        for (NetworkInterface subIf : Collections.list(subIfs)) {
            if (subIf.getName().equalsIgnoreCase(interfaceName)) {
...
StringgetInterfaceDiagnostic()
It provides a complete description of all available network interfaces in the system as well as the configured INET Addresses. 
StringBuilder description = new StringBuilder();
Enumeration<NetworkInterface> nets = NetworkInterface.getNetworkInterfaces();
for (NetworkInterface netIf : Collections.list(nets)) {
    description.append(describeInterface(netIf, false));
    description.append(displaySubInterfaces(netIf));
    description.append("\n");
return description.toString();
...
StringgetInterfaceInfo(NetworkInterface nif)
get Interface Info 
return getInterfaceInfo(nif, ":");
MapgetInterfaces()
get Interfaces 
Map<String, String> interfaces = new HashMap<String, String>();

ListgetInterfaces()
Return all interfaces (and subinterfaces) on the system 
List<NetworkInterface> all = new ArrayList<NetworkInterface>();
