Handling more than one jcombox in actionPerformed.

Question

HI, am having a little difficulty recognising events in the event handler. Basically, my program has two comboBoxes and a button.
so if one combobox item changes, when search is clicked, i want it to update the panel accordingly, also, if two comboboxes are selected, get the item selected of the first combobox and use it as a search criteria for the action performed in the second combobox.....
ive tried a variety of ways but this is the best i could do....
searchButton.addActionListener(new ActionListener(){
          public void actionPerformed(ActionEvent ae) {
          createDialog(); //this method creates a jdialog and addsa textArea to the panel...
doing this causes an error:
if(event.getActionCommand()=="course"){
     String courseName = (String)coursesComboBox.getSelectedItem();
     final String newline = "\n";
     popUp.setTitle("Modules Available to "+ courseName);
     PrintModules print = new PrintModules("DissertationOntology.owl");
     ArrayList modules = print.ListModules("mod");
     int size = modules.size();
     for(int i=0;i<size;i++){
          String mod = (String)modules.get(i);
          textArea.append(mod+ newline);
whereas doing this doesn't quite capture what am trying to achieve:
if ((event.getActionCommand()=="course")&&(event.getActionCommand()=="status")) {
     createDialog();
     String courseName = (String)coursesComboBox.getSelectedItem();
     final String newline = "\n";
     popUp.setTitle("Modules Available to "+ courseName);
     PrintModules print = new PrintModules("DissertationOntology.owl");
     ArrayList modules = print.ListCompulsoryModules("mod");
     int size = modules.size();
     for(int i=0;i<size;i++){
          String mod = (String)modules.get(i);
          textArea.append(mod+ newline);
Any form of assistance would be greatly appreciated...
thanks alot
