java中Socket编程（二）

public class Client {
    public static void main(String[] args) throws Exception {
        // 定义服务器IP地址和监听的端口号
        String serverIp = "127.0.0.1";
        int port = 8888;

        // 创建客户端Socket实例，向服务器Socket发送连接请求
        Socket socket = new Socket(serverIp, port);
        System.out.println("Connect to server.");

        // 获取输出流，向服务器Socket发送数据
        OutputStream outputStream = socket.getOutputStream();
        outputStream.write("Hello, Server!".getBytes());

        // 获取输入流，接收服务器Socket发送的数据
        InputStream inputStream = socket.getInputStream();
        byte[] buffer = new byte[1024];
        int len = inputStream.read(buffer);
        String data = new String(buffer, 0, len);

        // 处理服务器Socket发送的数据
        System.out.println("Server Response: " + data);

        // 关闭Socket连接
        socket.close();
    }
