**服务端代码**

import java.io.BufferedReader;
    import java.io.IOException;
    import java.io.InputStreamReader;
    import java.net.ServerSocket;
    import java.net.Socket;
    
    public class SocketServer {
    
    	public static void main(String[] args) throws IOException {
    		System.out.println("---------------------服务开启-----------------------");
    		// 建立端口，监听新的请求
    		ServerSocket ss = new ServerSocket(9856);
    		Socket s = ss.accept();
    
    		// 读取客户端输入的信息
    		BufferedReader br = new BufferedReader(new InputStreamReader(s.getInputStream()));
    
    		String line = null;
    		// 进行输出
    		while ((line = br.readLine()) != null) {
    			System.out.println("-----客户端输入的信息是-----");
    			System.out.println(line);
    		}
    		s.close();
    	}
    }

**客户端代码**

import java.io.BufferedReader;
    import java.io.BufferedWriter;
    import java.io.IOException;
    import java.io.InputStreamReader;
    import java.io.OutputStreamWriter;
    import java.net.Socket;
    import java.net.UnknownHostException;
    
    public class Client {
    
    	public static void main(String[] args) throws UnknownHostException, IOException {
    
    		// 建立连接
    		Socket s = new Socket("127.0.0.1", 9856);
    
    		// 读取键盘输入流
    		BufferedReader br = new BufferedReader(new InputStreamReader(System.in));
    
    		// 端口输出
    		BufferedWriter bw = new BufferedWriter(new OutputStreamWriter(s.getOutputStream()));
    
    		String line = null;
    
    		// 输入886结束输出
    		while ((line = br.readLine()) != null) {
    			if ("886".equals(line)) {
    				break;
    			}
    			bw.write(line);
    			bw.newLine();
    			bw.flush();
    		}
    		s.close();
    	}
    }
