以下是一个使用Java代码从API端点接收API响应的示例：

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

public class ApiExample {
    public static void main(String[] args) {
        try {
            // 创建URL对象
            URL url = new URL("https://api.example.com/endpoint");

            // 创建HttpURLConnection对象
            HttpURLConnection conn = (HttpURLConnection) url.openConnection();

            // 设置请求方法为GET
            conn.setRequestMethod("GET");

            // 获取API响应的状态码
            int responseCode = conn.getResponseCode();

            // 根据状态码判断请求是否成功
            if (responseCode == HttpURLConnection.HTTP_OK) {
                // 读取API响应内容
                BufferedReader reader = new BufferedReader(new InputStreamReader(conn.getInputStream()));
                String line;
                StringBuilder response = new StringBuilder();
                while ((line = reader.readLine()) != null) {
                    response.append(line);
                }
                reader.close();

                // 打印API响应内容
                System.out.println(response.toString());
            } else {
                System.out.println("请求失败，状态码：" + responseCode);
            }

            // 关闭连接
            conn.disconnect();
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}

以上代码使用java.net.URL和java.net.HttpURLConnection类来发送GET请求到API端点，并从API响应中读取内容。请替换https://api.example.com/endpoint为实际的API端点URL。
