Java 的通信编程，编程题(或问答)，用JAVA SOCKET编程，读服务器几个字符，再写入本地显示？

public class Server {
	
	public static final int SERVER_PORT = 8888;
	
	public void startServer() {
		try {
			ServerSocket ss = new ServerSocket(SERVER_PORT);
			//时刻监听客户端的连接
			while(true) {
				//接手客户端的连接
				Socket s = ss.accept();
				//得到接收的这个Socket的输入流，并封装成一个BufferedReader()
				BufferedReader br = new BufferedReader(new InputStreamReader(s.getInputStream()));
				
				//将从客户端接收到的数据在发送回客户端
				PrintWriter pw = new PrintWriter(s.getOutputStream(), true);
				pw.println(br.readLine());
				//关闭相应的资源
				br.close();
				pw.close();
				s.close();
				System.err.println(br.readLine());
			}
		} catch (IOException e) {
		}
	}
	
	public static void main(String[] args) {
		new Server().startServer();
	}
}

public class Client {
	public void connServer() {
		try {
			//建立与服务器端的链接
			Socket s = new Socket("localhost",Server.SERVER_PORT);
			//监听键盘事件，等待用户输入字符串
			Scanner sc = new Scanner(System.in);
			//得到Socket的输入流封装成一个PrintWriter
			PrintWriter pw = new PrintWriter(s.getOutputStream(), true);
			//把用户输入的字符写出去
			pw.println(sc.nextLine());
			
			//得到服务器端的输入流并封装成BufferedReader对象
			BufferedReader br = new BufferedReader(new InputStreamReader(s.getInputStream()));
			System.out.println(br.readLine() + "服务器发送给我的数据");
			
		} catch (UnknownHostException e) {
		} catch (IOException e) {
		}
	}
	
	public static void main(String[] args) {
		new Client().connServer();
	}
}
