how list of ip addresses devices connected same subnet using java?

this should work when hosts on network react icmp packages (ping) (>jdk 5):

public void checkhosts(string subnet){    int timeout=1000;    (int i=1;i<255;i++){        string host=subnet + "." + i;        if (inetaddress.getbyname(host).isreachable(timeout)){            system.out.println(host + " reachable");        }    } }

invoke method subnet (192.168.0.1-254) this: 

checkhosts("192.168.0");

didnt test should work kinda this. checks 254 hosts in last byte of ip address...

check:
