Here is the code snippet. Can somebody help me convert byte arrays to
String? Here is the code snippet:

InetAddress addr = InetAddress.getLocalHost();
byte[] ipAddr = addr.getAddress();

Errr...
String strIP = new String(ipAddr);

Is it what you mean?

You don't. InetAddress has a method (poorly named) to return the raw IP
address as a string:

String addressString = addr.getHostAddress();

You don't want to do the conversion yourself because some day you may be
dealing with IPV6 addresses which are 128-bit and do not use dots. If
you use the method above you will work with IPV4 and IPV6 and whatever
comes along after that.

Good point about the IPv6 addresses. Lots of colons and not so many dots.
