thx, regex solved my problem two years ago ... btw makasih loh
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

You've sized the output array based on the input
String[] which the OP doesn't have.Arjun Nurdin
Same sir error line 3
(String)jsonArray.getJSONObject(i)user3322481
Did you add
import org.json.JSONArray; in your code?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();
}
}

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.
