Socket基础编程

1、服务器端代码如下

package com.njupt.webservice;

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStream;
import java.io.InputStreamReader;
import java.net.ServerSocket;
import java.net.Socket;

public class Server {

	public static void main(String[] args) throws Exception {
		ServerSocket ss = new ServerSocket(6789);
		
		while(true){
			Socket s =  ss.accept();
			InputStream is = s.getInputStream();
			
			BufferedReader br = new BufferedReader(new InputStreamReader(is));
			String str = br.readLine();
			
			System.out.println("客户端说：" + str);
			
			br.close();
			is.close();
			s.close();
			
		}
	}
}

2、客户端代码如下：

package com.njupt.webservice;

import java.io.BufferedWriter;
import java.io.IOException;
import java.io.OutputStream;
import java.io.OutputStreamWriter;
import java.net.Socket;
import java.net.UnknownHostException;

public class Client {

	public static void main(String[] args) throws Exception {
		Socket s = new Socket("127.0.0.1",6789);
		
		OutputStream os = s.getOutputStream();
		
		BufferedWriter bw = new BufferedWriter(new OutputStreamWriter(os));
		
		bw.write("我喜欢章泽天?");
		
		bw.close();
		os.close();
		s.close();
	}
}
