  static void showInfo (InputStream inputStream) 
        BufferedReader bufferedReader = null;
        try 
            bufferedReader = new BufferedReader(new InputStreamReader(inputStream, "gbk"));
            String line = null;
            while ((line = bufferedReader.readLine()) != null) 
                System.out.println(line);
            
         catch (Exception e) 
            e.printStackTrace();
         finally 
            if (bufferedReader != null) 
                try 
                    bufferedReader.close();
                 catch (IOException e) 
                    e.printStackTrace();
                
            
        
    ;

使用

Process process = Runtime.getRuntime().exec("ping baidu.com");
showInfo (process.getInputStream());
process.waitFor();
System.out.println(process.exitValue());
