服务器端

package com.sherlock.nio;

import java.io.IOException;
import java.io.InputStream;
import java.io.OutputStream;
import java.net.InetAddress;
import java.net.ServerSocket;
import java.net.Socket;

import javax.swing.plaf.synth.SynthSpinnerUI;

public class Test01_Server {
	public static void main(String[] args) throws IOException {
		//实例化一个 套接字对象 传入 Port端口号[0-65535]
		ServerSocket server = new ServerSocket(10000);
		//接受客户端的连接 返回一个socket
		//专门负责与 指定客户通信
		Socket socket = server.accept();
		InputStream is = socket.getInputStream();
		OutputStream os = socket.getOutputStream();
		os.write("欢迎访问中北网站".getBytes());
		
		byte[] arr = new byte[1024];

		len = is.read(arr);
		System.out.println("收到客户端消息："+ new String(arr,0,len));
		socket.close();

	}

客户端

package com.sherlock.nio;

import java.io.IOException;
import java.io.InputStream;
import java.io.OutputStream;
import java.net.Socket;
import java.net.UnknownHostException;

public class Test02_Client {
	public static void main(String[] args) throws UnknownHostException, IOException {
		Socket socket = new Socket("127.0.0.1",10000);
		//获取通信io流
		InputStream is = socket.getInputStream();
		OutputStream os = socket.getOutputStream();
		//按照逻辑 去接受发送数据
		//收去服务器发送过来的数据
		
		byte[] buf = new byte[1024];
		int len;
		len = is.read(buf);
		System.out.println("从服务器收到消息："+ new String(buf,0,len));
		
		os.write("我想咨询点事" .getBytes());
		socket.close();
	}
