Answer 1

You can use java's InetAddress class for this purpose.

InetAddress IP=InetAddress.getLocalHost();
System.out.println("IP of my system is := "+IP.getHostAddress());

Output for my system = IP of my system is := 10.100.98.228

getHostAddress() returns

Returns the IP address string in textual presentation.

OR you can also do

InetAddress IP=InetAddress.getLocalHost();
System.out.println(IP.toString());

Output = IP of my system is := RanRag-PC/10.100.98.228
