Java怎么提取ping返还结果中的信息

Question

JAVA如何做到这条要求，目前代码输入网址和数据包次数可以返还结果，如何提取这个结果中的time信息

package ping;
import java.io.BufferedReader;
import java.io.InputStreamReader;
import java.net.InetAddress;
import java.util.Scanner;


public class Ping {

    public static boolean ping(String ipAddress) throws Exception {
        int  timeOut =  3000 ;  //超时应该在3钞以上        
        boolean status = InetAddress.getByName(ipAddress).isReachable(timeOut);     // 当返回值是true时，说明host是可用的，false则不可。
        return status;
    }

   public static void ping02(String ipAddress,int nofecho) throws Exception {
        String line = null;
        try {
            Process pro = Runtime.getRuntime().exec("ping " + "/n " + nofecho + " " +ipAddress );
            BufferedReader buf = new BufferedReader(new InputStreamReader(
                    pro.getInputStream()));
            while ((line = buf.readLine()) != null)
                System.out.println(line);
        } catch (Exception ex) {
            System.out.println(ex.getMessage());
        }
    }
    public static void main(String[] args) throws Exception {
        Scanner in = new Scanner(System.in);
        String ipAddress = in.nextLine();
        int nofecho = in.nextInt();
        ping02(ipAddress,nofecho);
    }
}
