Hi all, i've this code below which prompts a user to select from a list of ip addresses.e.g 192.168.2.1....etc. Now i wona modify this code so that if the machine on which the program is run has a different network part (192.168.2.) then I can prompt the user to enter their network ID e.g (148.145.23.) then increment the last bit using a for loop. Anyone able to help me out pls? thanks in advance

I have added this block of code below in order to do this but it doesnt work:

(Toggle Plain Text)

System.out.print("Enter your network part or hit enter to proceed: ");
            String network = in.readString();
            
            //test
            System.out.println(network);
            
            //if enter is pressed - same network
            if (network == null)
        
            {
            
            System.out.print("SELECT A MACHINE TO VIEW FROM LIST: ");
            int choice = in.readInteger();
            }

            else
            {
                //pass new network part to ip string variable
                ip = network;
            }
