Java网络编程：ServerSocket、Socket通信示例

在Java中，服务器通过Socket通信。以下是一个简单的ServerSocket和Socket通信的示例：

创建ServerSocket（监听客户端连接）：
```java
import java.io.ServerSocket;
import java.util.Scanner;

public class Server {
private static final int PORT = 8080; // 选择监听端口

public static void main(String[] args) throws Exception {
    // 创建一个服务器端口对象
    ServerSocket serverSocket = new ServerSocket(PORT);
    Scanner scanner = new Scanner(System.in);
    System.out.println("Server is listening on port " + PORT);
    System.out.println("Type 'connect' to connect with the server...");
    while (true) {
        // 等待客户端连接
        Socket socket = serverSocket.accept();
        System.out.println("\nClient has connected from IP: " + socket.getRemoteSocketAddress()));
        scanner.nextLine(); // 读取客户端命令
        if ("connect".equals(scanner.nextLine()))) {
            System.out.println("Connection established with client.");
        } else {
            System.out.println("Invalid command. Please try again.");
        }
        // 关闭socket连接
        socket.close();
    }
}
