使用java 执行ping命令

借助 Runtime.getRuntime().exec() 可以运行一个windows的exe程序
如图，使用java运行 ping 192.168.2.106，返回这样的字符串

 

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23

package socket;   import java.io.BufferedReader; import java.io.IOException; import java.io.InputStreamReader;   public class TestSocket {       public static void main(String[] args) throws IOException {           Process p = Runtime.getRuntime().exec("ping " + "192.168.2.106");         BufferedReader br = new BufferedReader(new InputStreamReader(p.getInputStream()));         String line = null;         StringBuilder sb = new StringBuilder();         while ((line = br.readLine()) != null) {             if (line.length() != 0)                 sb.append(line + "\r\n");         }         System.out.println("本次指令返回的消息是：");         System.out.println(sb.toString());     }   }
