How to return more than one object from SwingWorker

Question

I am using a SwingWorker to call 3 different methods of another class (data fetch class). Each of these 3 methods returns a String array. I am able to get the first array outside the thread code using the get() method of the SwingWorker class,
final String tmpOrdNum = OrderNum;
SwingWorker worker = new SwingWorker() {
     DATA_FETCH_TO_ARRAY data_fetch = new DATA_FETCH_TO_ARRAY(tmpOrdNum);
     public Object construct(){
          String [] orderArr = data_fetch.getHeaderArray();
          //String [] detailArr = data_fetch.getDetailArray();
          //String [] storeArr = data_fetch.getStoreArray();                    
          return orderArr;
     //Runs on the event-dispatching thread.
     public void finished(){     }
worker.start() ;
String[] testArr = (String[])worker.get();      //gets the header array
/* HOW DO I GET THE DETAIL AND STORE ARRAYS HERE?*/I want to be able to call the other 2 methods of the data fetch class - getDetailArray() and getStoreArray() shown commented in the above code one by one.
Can someone please suggest a way of doing this? Thank you.

Answer 1

Return String[][] from construct method.
Here is an example (observe test method):
import java.util.*;
public class ArrayTest{
     public static void main(String[] args){
          String[][] result=(String[][])new ArrayTest().test();          
          System.out.println("result1: "+Arrays.toString(result[0]));
          System.out.println("result2: "+Arrays.toString(result[1]));
          System.out.println("result3: "+Arrays.toString(result[2]));
     public Object test(){
          String[] str1={"A","B","C"};
          String[] str2={"M","N","O"};
          String[] str3={"X","Y","Z"};          
          String[][] out=new String[3][];
          out[0]=str1;
          out[1]=str2;
          out[2]=str3;
          return out;
}Thanks,
