用JSONArray中的空字符串替换所有空值

Question

嗨,我有一个JSONObject,我已经转换为JSON数组,我想知道如何遍历整个数组找到任何null的实例,并用""替换它？

继续我到目前为止,但不知道从哪里开始

JSONObject fullNetworkfile = fullNetworkDataFromFile;
     JSONArray fullNetworkArray = new JSONArray();
     fullNetworkArray.put(fullNetworkfile);

Answer 1

for (int i = 0; i < fullNetworkArray.length(); i++) {
    Object network = fullNetworkArray.get(i);
    if (network == null) {
        fullNetworkArray.put(i, "");
    }
}
