以下程序执行了：ipconfig /all命令

Process process = null;
        StringBuilder message = new StringBuilder();
        List<String> commandList = new ArrayList<String>();
        commandList.add("ipconfig");
        commandList.add("/all");
        try{
            ProcessBuilder builder = new ProcessBuilder(commandList);
            builder.redirectErrorStream(true);
            //builder.directory();
            process = builder.start();
            BufferedReader in = new BufferedReader(
            new InputStreamReader(process.getInputStream()));
            String line = null;
            while ((line = in.readLine()) != null) {
                System.out.println(line);
                message.append(line + System.getProperty("line.separator"));
            }
    
            process.waitFor();
        }catch (Exception e) {
            // TODO: handle exception
        }finally{
            if (process != null)
                process.destroy();
        }
        process.destroy();
        
        System.out.println("process.exitValue():" +process.exitValue());
