testclient.java

自己做的一个QQ聊天系统

package test.socket;

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
import java.io.PrintWriter;
import java.net.Socket;//java的网络包
import java.net.UnknownHostException;

public class TestClient {

	/**
	 * @param args
	 * @throws IOException 
	 * @throws UnknownHostException 
	 */
	public static void main(String[] args) throws UnknownHostException, IOException {
		// TODO Auto-generated method stub
        Socket s = new Socket("127.0.0.1",8888);
        PrintWriter pw = new PrintWriter(s.getOutputStream());//获取输出流
        pw.println("我爱北京");
        pw.flush();//把内容真正的放进去 原数据在缓冲区内
        BufferedReader br = 
        	new BufferedReader(
        			new InputStreamReader(
        					s.getInputStream()));
        System.out.println(br.readLine());
        s.close();//关闭Socket		
	}
