I wrote the following code to get the IPv4 address of the eth0 interface I am using on a machine. However the code only finds fe80:x:x:x:xxx:xxxx:xxxx:xxxx
which is not returned since I am looking for the IPv4 address.
Here is the code.
interfaceName = "eth0";
NetworkInterface networkInterface = NetworkInterface.getByName(interfaceName);
Enumeration<InetAddress> inetAddress = networkInterface.getInetAddresses();
InetAddress currentAddress;
currentAddress = inetAddress.nextElement();
while(inetAddress.hasMoreElements())
{
System.out.println(currentAddress);
if(currentAddress instanceof Inet4Address && !currentAddress.isLoopbackAddress())
{
ip = currentAddress.toString();
break;
}
currentAddress = inetAddress.nextElement();
}
It was messing with the logic where it gets the next element. I had the
inetAddress
next element being gotten before thewhile
compare was ran. Thus making there be no more elements.The following code has then fixed the logic
