第一次尝试Java的Socket

Server


package practice;




import java.io.*;


import java.net.*;






public class DailyAdviceServer ...{




String[] messageList = ...{"心情：较差", "总运指数：★★☆☆☆",


"你此日情绪不太稳定，很强的道德观念使得你对那些不重视公共环境的人深恶痛绝，搞不好还会恶语相加，弄得你心情不好。",


"幸运数字：1", "开运运动：保龄球", "开运食品：木瓜", "开运服饰：格子装", "开运歌曲：关于你的歌（李圣杰）"};




/** *//**


* @param args


*/




public static void main(String[] args) ...{


(new DailyAdviceServer()).go();


}






private void go()...{




try...{


ServerSocket serverSocket = new ServerSocket(4242);






while(true)...{


Socket socket = serverSocket.accept();




PrintWriter printWriter = new PrintWriter(socket.getOutputStream());


String advice = getAdvice();


printWriter.println(advice);


printWriter.close();


System.out.println(advice);


}// end while






}catch(Exception e)...{


e.printStackTrace();


}


}






private String getAdvice()...{


return messageList[(int)(Math.random()*8)];


}


}



client


package practice;




import java.io.*;


import java.net.*;






public class DailyAdviceClient ...{




public static void main(String[] args)...{


(new DailyAdviceClient()).go();


}




private void go()...{




try...{


Socket socket = new Socket("127.0.0.1",4242);


InputStreamReader inputStreamReader = new InputStreamReader(socket.getInputStream());


BufferedReader reader = new BufferedReader(inputStreamReader);




String advice = reader.readLine();


System.out.println("advice is : " + advice);




reader.close();




}catch(Exception e)...{


e.printStackTrace();


}


}


}



第一次练习，单线程的Socket读写，just Try。
