Network Programming Back

• Network實現的重要機制:Socket

Step	Server	Client
1	ServerSocket s = new ServerSocket(port);
1	Socket client = s.accept();
2		Socket client = new Socket(host, port);
3	readfromclient = new BufferedReader(new InputStreamReader(client.getInputStream()));	readfromserver = new BufferedReader(new InputStreamReader(socket.getInputStream()));
3	writetoclient = new PrintWriter(client.getOutputStream());	writetoserver = new PrintWriter(client.getOutputStream());
4	readfromclient.close();	readfromserver.close();
4	writetoclient.close();	writetoserver.close();
4	client.close();	client.close();

• Stream, Socket等聲明需放在try外. 因為若放try內, 作用於只在try範圍內
