如何在多个文件夹中保存StringJSON元素

Question

我有一个包含70个对象的JSON文件，每个对象都包含数组等元素。以下是JSON对象的示例：

{ 
   "journal": ".....",
   "category": ["Sport", "football", "Real Madrid"],
   "abstract": "Here is an example"
} 

首先，我使用元素"category"的Strings创建文件夹。下一步是根据元素"abstract"的字符串创建一个.txt文件。我想做的是将每个.txt文件保存在这些文件夹中。

例如，元素"abstract"包含字符串"Here is an example"，我用这个短语创建了一个.txt文件，我想知道如何将其保存在文件夹Sport、Football和Real Madrid中。

Answer 1

下面是一些示例java:

// create a list of folder names and call it "folderArray".
// You are already doing something like this, but I don't know the variable name.
// You also have the name of the abstract text file name in a variable.
// This code assumes that variable is called "abstractFileName".
for (final String folder : folderArray)
{
    final String newFileName = folder + File.separatorChar + abstractFileName;
    // create a file with the name "newFileName"
    // Write the abstract contents to the new file.
}

Answer 2

JSONObject obj = new JSONObject(jsonString);
JSONArray arr = obj.getJSONArray("category");
File f = new File("C:/Files");
for(int i = 0; i < arr.length; i++)
{
  String folderName = arr.getString(i);
  File folder = new File(folderName);
  if(folder.mkdir()) {
    File file = new File(folderName + "fileName.txt");
    String data = obj.getString("abstract");
    // Now using stream write the data to this file
    DataOutputStream dos = new DataOutputStream(FileOutputStream(file));
    dos.writeUTF(data);
}
