如何在java中删除嵌套的JSONObject键和值

JSONObject jsonObject = new JSONObject();

jsonObject.put("key1", "value1");
JSONObject nestedObject = new JSONObject();
nestedObject.put("nestedKey", "nestedValue");
jsonObject.put("key2", nestedObject);

public static void deleteNestedKeyValue(JSONObject jsonObject, String keyPath) {
    String[] keys = keyPath.split("\\.");

    JSONObject currentObject = jsonObject;
    for (int i = 0; i < keys.length - 1; i++) {
        if (currentObject.has(keys[i])) {
            Object obj = currentObject.get(keys[i]);
            if (obj instanceof JSONObject) {
                currentObject = (JSONObject) obj;
            } else {
                return; // 嵌套的键路径不存在
            }
        } else {
            return; // 嵌套的键路径不存在
        }
    }

    if (currentObject.has(keys[keys.length - 1])) {
        currentObject.remove(keys[keys.length - 1]);
    } else {
        return; // 嵌套的键路径不存在
    }
}

deleteNestedKeyValue(jsonObject, "key2.nestedKey");

System.out.println(jsonObject.toString());

import org.json.JSONObject;

public class Main {
    public static void main(String[] args) {
        JSONObject jsonObject = new JSONObject();
        jsonObject.put("key1", "value1");

        JSONObject nestedObject = new JSONObject();
        nestedObject.put("nestedKey", "nestedValue");
        jsonObject.put("key2", nestedObject);

        deleteNestedKeyValue(jsonObject, "key2.nestedKey");

        System.out.println(jsonObject.toString());
    }

    public static void deleteNestedKeyValue(JSONObject jsonObject, String keyPath) {
        String[] keys = keyPath.split("\\.");

        JSONObject currentObject = jsonObject;
        for (int i = 0; i < keys.length - 1; i++) {
            if (currentObject.has(keys[i])) {
                Object obj = currentObject.get(keys[i]);
                if (obj instanceof JSONObject) {
                    currentObject = (JSONObject) obj;
                } else {
                    return; // 嵌套的键路径不存在
                }
            } else {
                return; // 嵌套的键路径不存在
            }
        }

        if (currentObject.has(keys[keys.length - 1])) {
            currentObject.remove(keys[keys.length - 1]);
        } else {
            return; // 嵌套的键路径不存在
        }
    }
