网络抓包程序用java实现

import java.io.*;
import java.sql.*;
import jpcap.*;
public class Main 
{
	          
	static long start;
	 public static void main(String[] args) throws java.io.IOException,SQLException
	 {	
	   NetworkInterface[] devices =JpcapCaptor.getDeviceList();
	   for(int i=0;i<devices.length;++i)
	     System.out.println(devices[i].name);
	  JpcapCaptor jpcap = JpcapCaptor.openDevice(devices[1],65535,true, 20);
	   File FilePath=new File("E:");
	   File f1=new File(FilePath,"packet.txt");
	   FileOutputStream fout=new FileOutputStream(f1);
	   DataOutputStream dout=new DataOutputStream(fout);
	   start=System.currentTimeMillis();//记录抓包的开始时间
	   for(int k=0;k<3000;++k)
	   {
	     jpcap.loopPacket(1, new catchbao());//抓包
	     dout.writeBytes(catchbao.sting);//将数据包写入文件
	   }
	   Catchcount.Catchcount(String []args);//统计各种协议数据包数量
	   //ComLen.comlen();//统计各种长度数据包的数量；
	   Drawpicture frame=new Drawpicture();//画出数据包流量图
	   frame.setVisible(true);
	 }
