如何将curl命令转换为java命令

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

public class CurlToJavaConverter {
    public static void main(String[] args) throws Exception {
        // 设置URL和curl命令
        String url = "https://api.example.com/endpoint";
        String curlCommand = "curl -X POST -H 'Content-Type: application/json' -d '{\"key\": \"value\"}' " + url;
        
        // 解析curl命令
        String[] curlParts = curlCommand.split(" ");
        String httpMethod = curlParts[1];
        String requestData = curlParts[curlParts.length - 1];
        
        // 创建URL对象
        URL requestUrl = new URL(url);
        
        // 打开连接
        HttpURLConnection connection = (HttpURLConnection) requestUrl.openConnection();
        
        // 设置HTTP方法
        connection.setRequestMethod(httpMethod);
        
        // 设置请求头
        for (int i = 2; i < curlParts.length - 1; i += 2) {
            String headerName = curlParts[i].substring(2);
            String headerValue = curlParts[i + 1].replaceAll("'", "");
            connection.setRequestProperty(headerName, headerValue);
        }
        
        // 发送请求
        connection.setDoOutput(true);
        connection.getOutputStream().write(requestData.getBytes("UTF-8"));
        
        // 获取响应
        int responseCode = connection.getResponseCode();
        BufferedReader reader;
        if (responseCode == HttpURLConnection.HTTP_OK) {
            reader = new BufferedReader(new InputStreamReader(connection.getInputStream()));
        } else {
            reader = new BufferedReader(new InputStreamReader(connection.getErrorStream()));
        }
        
        String line;
        StringBuilder response = new StringBuilder();
        while ((line = reader.readLine()) != null) {
            response.append(line);
        }
        reader.close();
        
        // 打印响应结果
        System.out.println(response.toString());
    }
}
