public class GetLocalIP {

    public static void main(String[] args) {

        try {

            InetAddress addr = InetAddress.getLocalHost();

            String ip=addr.getHostAddress().toString();//获得本机IP

            String address=addr.getHostName().toString();//获得本机名称

            System.out.println(ip+"--------------"+address);

        } catch (UnknownHostException e) {

            e.printStackTrace();
