Java Socket编程是通过使用Java的Socket类和ServerSocket类来实现网络通信的方法。下面是一个简单的示例,演示了如何使用Java Socket编程来实现客户端服务器端之间的通信。

服务器端示例:

import java.io.*;import java.net.*;public class Server {    public static void main(String[] args) {        try {            ServerSocket serverSocket = new ServerSocket(12345);            System.out.println("Server is running and waiting for client to connect...");            Socket clientSocket = serverSocket.accept();            System.out.println("Client connected.");            BufferedReader in = new BufferedReader(new InputStreamReader(clientSocket.getInputStream()));            PrintWriter out = new PrintWriter(clientSocket.getOutputStream(), true);            String inputLine;            while ((inputLine = in.readLine()) != null) {                System.out.println("Client: " + inputLine);                out.println("Server received: " + inputLine);            }            in.close();            out.close();            clientSocket.close();            serverSocket.close();        } catch (IOException e) {            System.out.println("Error: " + e.getMessage());        }    }}

```

客户端示例:

import java.io.*;import java.net.*;public class Client {    public static void main(String[] args) {        try {            Socket socket = new Socket("localhost", 12345);            PrintWriter out = new PrintWriter(socket.getOutputStream(), true);            BufferedReader in = new BufferedReader(new InputStreamReader(socket.getInputStream()));            BufferedReader userInput = new BufferedReader(new InputStreamReader(System.in));            String userInputLine;            while ((userInputLine = userInput.readLine()) != null) {                out.println(userInputLine);                System.out.println("Server: " + in.readLine());            }            out.close();            in.close();            userInput.close();            socket.close();        } catch (IOException e) {            System.out.println("Error: " + e.getMessage());        }    }}

```

在上面的示例中,服务器端通过ServerSocket监听指定端口,当客户端连接时,接受连接并创建输入输出流。客户端通过Socket连接到服务器端,并创建输入输出流进行通信。这样就实现了简单的网络通信。
