i'm put the JSONArray to the string toString(), and i'm convert by regular expression like this ..

public String getImg(String d){
    return rubahFormat(d).split(",");
}

public String rubahFormat(String d){
    return d.replaceAll("[\\[\\]\\\"]","");
}

Thx ..

You can use Java Streams to do that for you:

    String[] data = new String[] { "value1", "value2", "value3" };
    String jsonArray = "[\"" + Stream.of(data).collect(Collectors.joining("\", \"")) + "\"]";

The steam collector adds the ", " between two values. Now simply add the [" at the beginning, and the corresponding end.

You should try like this and it will help you

import net.sf.json.JSONArray;

public class JsonArraytoArray {

    JSONArray jsonArray = new JSONArray();

    public void convertJsonarrtoArray() {
        jsonArray.add("java");
        jsonArray.add("test");
        jsonArray.add("work");
        String[] stringArray = new String[jsonArray.size()];
        for (int i = 0; i < jsonArray.size(); i++) {
            stringArray[i] = jsonArray.getString(i);
        }
        System.out.println("stringArray  " + stringArray.length);
    }

    public static void main(String[] args) {
        JsonArraytoArray d = new JsonArraytoArray();
        d.convertJsonarrtoArray();
    }

}

String[] stringArray = new String[jsonArray.length()];
for (int i = 0; i < jsonArray.length(); i++) {
    stringArray[i]= (String)jsonArray.getJSONObject(i);
}

jsonArray is your JSON object and stringArray variable will store as string array type
