Create a Json Array without the Json Array name

I'm having problems creating a Json output in an array without the array name. Currently when I create one I get the following Json response.

{
  "values": [
    {
      "item1": "",
      "item2": "",
      "item3": "",
      "item4": ""
    }
  ]
}

But I want to remove following:

{
  "values": [
  ]
}

And have the end result look like the following:

[
   {
      "item1": "",
      "item2": "",
      "item3": "",
      "item4": ""
   },
   {
      "item1": "",
      "item2": "",
      "item3": "",
      "item4": ""
   }
]

Here is my code I'm currently using.

JSONArray jsonArray = new JSONArray();
jsonArray.put(new File(getFileName(base64), MimeTypes.ContentType(FileExtension.getType(base64)), folder, convertUriToBase64(), null));

Log.d(TAG, JsonUtil.toJson(jsonArray));

And here is my model class:

public class File {

    String fileName;
    int fileType;
    String fileFolder;
    String base64String;
    byte[] bytes;

    public File(String fileName, int fileType, String fileFolder, String base64String, byte[] bytes){
        this.fileName = fileName;
        this.fileType = fileType;
        this.fileFolder = fileFolder;
        this.base64String = base64String;
        this.bytes = bytes;
    }
}

Any help will be useful thank you!

Don't mix JSON elements with your own model. Here's an example using Gson.toJson which produces the expected result:

package test;

import java.util.ArrayList;
import java.util.List;

import com.google.gson.Gson;

public class GsonTest {

    // Your model class
    public static class Test {
        private int x;
        private int y;
        public Test(int x, int y) {
            this.x = x;
            this.y = y;
        }
    }

    public static void main(String[] args) {
        List<Test> list = new ArrayList<>();
        list.add(new Test(1, 2));
        list.add(new Test(2, 3));
        System.out.println(new Gson().toJson(list));

        // output: [{"x":1,"y":2},{"x":2,"y":3}]

    }

}
