如何将此POST cURL请求转换为java代码

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

public class CurlToJava {
    public static void main(String[] args) {
        try {
            // 设置请求URL和参数
            URL url = new URL("http://example.com/api");
            String postData = "param1=value1&param2=value2";

            // 创建连接
            HttpURLConnection connection = (HttpURLConnection) url.openConnection();
            connection.setRequestMethod("POST");
            connection.setDoOutput(true);

            // 设置请求头
            connection.setRequestProperty("Content-Type", "application/x-www-form-urlencoded");

            // 发送POST请求
            OutputStream outputStream = connection.getOutputStream();
            outputStream.write(postData.getBytes());
            outputStream.flush();
            outputStream.close();

            // 获取响应
            int responseCode = connection.getResponseCode();
            BufferedReader reader = new BufferedReader(new InputStreamReader(connection.getInputStream()));
            String line;
            StringBuilder response = new StringBuilder();
            while ((line = reader.readLine()) != null) {
                response.append(line);
            }
            reader.close();

            // 输出响应结果
            System.out.println("Response Code: " + responseCode);
            System.out.println("Response Body: " + response.toString());
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}
