Help with displaying an object from one class to a text box in another

Question

Hi everyone,
Just a quick question
I have a public class called Order which is in a processing folder;
within this class I have a method which gets a sold basket (which is just a list of items sold)
and adds it to another array list;
public synchronized SoldBasket getOrderToPick()
throws OrderException
if (theWaitingTray.size()>0){
thePickingTray.add(theWaitingTray.remove(0));
System.out.print(""+toBePicked);
return toBePicked;
else{
return null;
The other class is a GUI which has a button called CHECK which is for the warehouse stock picker to see if any orders have been placed on the button I have this code;
public void actionPerformed( ActionEvent ae ) // Interaction
if ( theStock == null )
theAction.setText("No conmection");
return;
String actionIs = ae.getActionCommand();
try{
if ( actionIs.equals( Name.CHECK ) ){
theOutput.setText(""+theOrder.getOrderToPick());
catch(OrderException e){
System.out.print(e);
However I am still getting a null pointer exception any ideas??
Thanks !!

Answer 1

I don't see enough information here to be able to answer this question. Try
1) posting code here with code tags by using the CODE button above the Message window and checking your post with the Preview tab before posting it.
2) Posting a small bit of code that compiles without need for other files, classes or non-standard classes and illustrates your problem, an SSCCE.
Good luck.
