Java 네트워크 프로그래밍에서 소켓을 구성하고 사용하는 방법은 무엇입니까?

// 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);
