Java ネットワーク プログラミングでソケットを構成および使用するにはどうすればよいですか?

// 创建一个 ServerSocket 监听端口 8080 ServerSocket serverSocket = new ServerSocket(8080); // 创建一个 Socket 客户端连接到 localhost:8080 Socket clientSocket = new Socket("localhost", 8080);

// 接受客户端连接 Socket clientSocket = serverSocket.accept(); // 获取输入流和输出流 DataInputStream input = new DataInputStream(clientSocket.getInputStream()); DataOutputStream output = new DataOutputStream(clientSocket.getOutputStream()); // 读写数据 String message = input.readUTF(); output.writeUTF("Hello from server: " + message); // 关闭连接 clientSocket.close();

// 发送数据到服务器 DataOutputStream output = new DataOutputStream(clientSocket.getOutputStream()); output.writeUTF("Hello from client"); // 接收服务器响应 DataInputStream input = new DataInputStream(clientSocket.getInputStream()); String serverMessage = input.readUTF(); // 关闭连接 clientSocket.close();

ServerSocket serverSocket = new ServerSocket(8080); Socket clientSocket = serverSocket.accept(); BufferedReader input = new BufferedReader(new InputStreamReader(clientSocket.getInputStream())); PrintWriter output = new PrintWriter(clientSocket.getOutputStream(), true); while (true) { String message = input.readLine(); if (message == null || message.isEmpty()) { break; } output.println("Server: " + message); }

Socket clientSocket = new Socket("localhost", 8080); BufferedReader input = new BufferedReader(new InputStreamReader(clientSocket.getInputStream())); PrintWriter output = new PrintWriter(clientSocket.getOutputStream(), true); output.println("Hello from client"); String serverMessage = input.readLine(); System.out.println(serverMessage);
