如何使用java将顺序JSON对象转换为csv

import org.json.JSONArray;
import org.json.JSONObject;
import java.io.FileWriter;
import java.io.IOException;
import java.util.Iterator;

public static void jsonToCsv(JSONObject json, String csvFilePath) {
    try {
        FileWriter csvWriter = new FileWriter(csvFilePath);

        // 获取JSON对象的键作为CSV文件的表头
        Iterator<String> keys = json.keys();
        while (keys.hasNext()) {
            csvWriter.append(keys.next());
            if (keys.hasNext()) {
                csvWriter.append(",");
            }
        }
        csvWriter.append("\n");

        // 获取JSON对象的值并写入CSV文件
        Iterator<String> values = json.keys();
        while (values.hasNext()) {
            String key = values.next();
            csvWriter.append(json.getString(key));
            if (values.hasNext()) {
                csvWriter.append(",");
            }
        }

        csvWriter.flush();
        csvWriter.close();
    } catch (IOException e) {
        e.printStackTrace();
    }
}

public static void main(String[] args) {
    JSONObject json = new JSONObject("{\"name\":\"John\",\"age\":30,\"city\":\"New York\"}");
    String csvFilePath = "output.csv";
    jsonToCsv(json, csvFilePath);
}
