receiver.java

用java开发的一个简单的ftp

import java.io.*;
import java.net.*;

public class receiver
{
	public static void main(String [] args)
	{
		receiver frame = new receiver();
	}

	mt622_client t2;
	public receiver()
	{
		t2 = new mt622_client();
		t2.start();
	}

	class mt622_client extends Thread
	{
		public mt622_client(){}
		public void run()
		{
			String str1;
			String servername = "computer";  //server端计算机名称
			System.out.println("<client>");
			System.out.println("请发送消息给sever端计算机<"+servername+">"+"remoteport 901");
			try{
				DatagramSocket socket1 = new DatagramSocket();
				DatagramPacket packet1;
				while(true)
				{
					BufferedReader buffer1;
					buffer1 = new BufferedReader(new InputStreamReader(System.in));
					System.out.println("<client端>请输入信息:");
					//从键盘读取数据
					str1 = buffer1.readLine();
					byte[] outbuffer = new byte[str1.length()];
					outbuffer = str1.getBytes();
					InetAddress address = InetAddress.getByName(servername);
					//设定packet1对象的发送地址（address),发送port(901)
					//发送信息变量(outbuffer),信息长度(outbuffet.length)
					packet1 = new DatagramPacket(outbuffer,outbuffer.length,address,901);
					//发送对象
					socket1.send(packet1);
				}
			}
			catch(IOException e){}
