Java如何在星号中拨号

public class DialingExample {
    public static void main(String[] args) {
        try {
            // 创建Socket对象
            Socket socket = new Socket();

            // 获取目标服务器的IP地址
            InetAddress address = InetAddress.getByName("目标服务器IP地址");

            // 创建连接
            InetSocketAddress socketAddress = new InetSocketAddress(address, 80);
            socket.connect(socketAddress);

            // 发送拨号请求
            OutputStream outputStream = socket.getOutputStream();
            outputStream.write("拨号请求数据".getBytes());

            // 接收拨号结果
            InputStream inputStream = socket.getInputStream();

            int length = inputStream.read(buffer);

            // 处理拨号结果
            String result = new String(buffer, 0, length);
            System.out.println("拨号结果：" + result);

            // 关闭连接
            socket.close();
        } catch (IOException e) {
            e.printStackTrace();
