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

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());

    }
 
}
