静态方法如何返回其自己的抽象类- WebRequest的对象

public abstract class AbstractRequest {
    public abstract void sendRequest();
}

public class HttpRequest extends AbstractRequest {
    private String url;
    private String method;

    private HttpRequest(String url, String method) {
        this.url = url;
        this.method = method;
    }

    @Override
    public void sendRequest() {
        // 发送 HTTP 请求的具体实现
        // ...
        System.out.println("Sending HTTP request to " + url + " with method " + method);
    }

    public static AbstractRequest createHttpRequest(String url, String method) {
        return new HttpRequest(url, method);
    }
}

public class Main {
    public static void main(String[] args) {
        AbstractRequest request = HttpRequest.createHttpRequest("https://example.com", "GET");
        request.sendRequest();
    }
}
