我如何使用第三方Api，例如这个网站(在我的java代码中使用https://haveibeenpwned.com/API/v2)

import java.io.BufferedReader;
import java.io.InputStreamReader;
import java.net.HttpURLConnection;
import java.net.URL;

public class HaveIBeenPwnedAPIExample {
    public static void main(String[] args) {
        try {
            // 构建API请求URL
            String apiUrl = "https://haveibeenpwned.com/api/v2/breachedaccount/example@example.com";
            URL url = new URL(apiUrl);

            // 创建HTTP连接
            HttpURLConnection connection = (HttpURLConnection) url.openConnection();
            connection.setRequestMethod("GET");
            connection.setRequestProperty("User-Agent", "Mozilla/5.0");

            // 发送请求并获取响应
            int responseCode = connection.getResponseCode();
            if (responseCode == HttpURLConnection.HTTP_OK) {
                BufferedReader in = new BufferedReader(new InputStreamReader(connection.getInputStream()));
                String inputLine;
                StringBuilder response = new StringBuilder();

                while ((inputLine = in.readLine()) != null) {
                    response.append(inputLine);
                }
                in.close();

                // 处理API响应
                System.out.println(response.toString());
            } else {
                System.out.println("API请求失败，响应码：" + responseCode);
            }
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}
