Java执行cmd命令并接收返回结果

String command="ipconfig -all";String s="IPv4";String line = null;StringBuilder sb = new StringBuilder();Runtime runtime = Runtime.getRuntime();try {Process process = runtime.exec(command);BufferedReaderbufferedReader = new BufferedReader(new InputStreamReader(process.getInputStream()));while ((line = bufferedReader.readLine()) != null) {sb.append(line + "\n");if (line.contains(s)) {System.out.println(line);}}} catch (IOException e) {// TODO 自动生成的 catch 块e.printStackTrace();}//System.out.println(sb.toString());
