Java实现运行dos命令

public class Test2 {

   public static void main(String[] args) throws IOException {

         String[] cmd = new String[3];

         cmd[0] = "cmd.exe";

         cmd[1] = "/c";

         cmd[2] = "arp -a";

         Runtime rt = Runtime.getRuntime();    

      Process proc = rt.exec(cmd);

      InputStream isInputStreamReader= proc.getInputStream();

      BufferedReader bufferedReader=new BufferedReader(new InputStreamReader(isInputStreamReader));

      String length=null;

        int  i=0;

      while((length=bufferedReader.readLine())!=null)

      {

          System.out.println(length);

          i++;

      }

    }

}

public class Test2 {

   public static void main(String[] args) throws IOException {

         String[] cmd = new String[3];

         cmd[0] = "cmd.exe";

         cmd[1] = "/c";

         while(true)

        {

         System.out.println("输入你要运行的dos命令");

         //对于简单的一个命令可以使用Scanner来接收用户的输入但是对于有参数的命令就不能使用它。而是使用流来操作

        // Scanner  scanner=new Scanner(System.in);

         //使用流来操作避免用户输入用参数的命令

         InputStreamReader   IS=new InputStreamReader(System.in);

         BufferedReader     BR=new BufferedReader(IS);

          cmd[2]=BR.readLine();

       Runtime rt = Runtime.getRuntime();

       Process proc = rt.exec(cmd);

       InputStream isInputStreamReader= proc.getInputStream();

       new Thread1(isInputStreamReader).start();

       //线程让出资源

       try {

            Thread.currentThread().sleep(1000);

        } catch (InterruptedException e) {

            e.printStackTrace();

        }

    }

   }

}

class   Thread1  extends Thread

{

    private InputStream   is;

    public Thread1(InputStream  is) {

        this.is=is;

    }

   public  void  run()

   {

       InputStreamReader  isr=new InputStreamReader(is);

       BufferedReader  br=new BufferedReader(isr);

       String  Length=null;

       try {

            while((Length=br.readLine())!=null)

            {

               System.out.println(Length);

            }

    } catch (IOException e) {

        e.printStackTrace();

    }   

   }

}

用户可以输入dos命令带参数的命令
