import java.io.IOException;
import java.io.InputStream;
public class PSOutput {
     public static void main(String[] args) {
          try {
             String command = "cmd /c ipconfig";
             Process child = Runtime.getRuntime().exec(command);
             InputStream in = child.getInputStream();
             int c;
             StringBuilder sb = new StringBuilder();
             while ((c = in.read()) != -1) {
                 sb.append((char)c);
             in.close();
             printISP(sb.toString());
         } catch (IOException e) {
              e.printStackTrace();
     static void printISP(String output){
          String startPattern = ". : ";
          String endPattern = "\r\r\n";
          int beginIdx = output.indexOf(startPattern)+ startPattern.length();
          int endIdx = output.indexOf(endPattern, beginIdx);
          System.out.println(output.substring(beginIdx,endIdx));
}As you can see it is ugly and is not really a reliable process, not sure that there is another way though.
