Java網絡編程實戰案例涉及到創建一個簡單的聊天室,允許用戶在不同的終端上發送和接收消息。以下是一個簡化的示例,展示了如何使用Java Socket和ServerSocket類來實現這一功能:
import java.io.*;
import java.net.*;
public class Server {
public static void main(String[] args) throws IOException {
ServerSocket serverSocket = new ServerSocket(6000);
while (true) {
Socket socket = serverSocket.accept();
BufferedReader in = new BufferedReader(new InputStreamReader(socket.getInputStream()));
PrintWriter out = new PrintWriter(socket.getOutputStream(), true);
String inputLine;
while ((inputLine = in.readLine()) != null) {
System.out.println("收到消息: " + inputLine);
out.println("服務器已收到: " + inputLine);
}
socket.close();
}
}
}
import java.io.*;
import java.net.*;
public class Client {
public static void main(String[] args) throws IOException {
Socket socket = new Socket("localhost", 6000);
PrintWriter out = new PrintWriter(socket.getOutputStream(), true);
BufferedReader in = new BufferedReader(new InputStreamReader(socket.getInputStream()));
BufferedReader stdIn = new BufferedReader(new InputStreamReader(System.in));
String userInput;
while ((userInput = stdIn.readLine()) != null) {
out.println(userInput);
System.out.println("服務器回應: " + in.readLine());
}
socket.close();
}
}
這個例子展示了如何使用Java Socket和ServerSocket類進行基本的網絡通信。在實際應用中,可能需要處理更多的細節,如多線程、錯誤處理、加密等。
