java Socket编程（一）

服务器端

package com.robert.view;

import java.io.BufferedInputStream;
import java.io.DataInputStream;
import java.io.IOException;
import java.io.InputStream;
import java.net.ServerSocket;
import java.net.Socket;

public class ServerClient {

	public static void main(String[] args) {
		ServerSocket server = null;
		Socket  socket = null;
		InputStream inputStream = null;
		BufferedInputStream bis = null;
		DataInputStream dis = null;
		try {
			server = new ServerSocket(10000);
			socket = server.accept();
			inputStream = socket.getInputStream();
			bis = new BufferedInputStream(inputStream);
			dis = new DataInputStream(bis);
			System.out.println(dis.readUTF());
		} catch (IOException e) {
			e.printStackTrace();
		}finally
		{
			try {
				inputStream.close();
			} catch (IOException e) {
				e.printStackTrace();
			}
		}
	}

}

客户端

package com.robert.view;

import java.io.BufferedOutputStream;
import java.io.DataOutputStream;
import java.io.IOException;
import java.io.OutputStream;
import java.net.Socket;
import java.net.UnknownHostException;

public class CustomerClient {


	public static void main(String[] args) {
		OutputStream outputStream = null;
		BufferedOutputStream bos = null;
		DataOutputStream dos = null;
		try {
			Socket socket = new Socket("localhost",10000);
			outputStream = socket.getOutputStream();
			bos = new BufferedOutputStream(outputStream);
			dos = new DataOutputStream(bos);
			dos.writeUTF("hello world");	
			dos.flush();
		} catch (UnknownHostException e) {
			e.printStackTrace();
		} catch (IOException e) {
			e.printStackTrace();
		}finally
		{
			try {
				outputStream.close();
			} catch (IOException e) {
				e.printStackTrace();
			}
		}
	}
