URGENT: Strange behaviour! Help!

Question

Hi All.
When I run the enclosed program I am getting some strange behaviour. For instance, when I click on the EDIT button nothing happens, but when I click on the DELETE button everything is fine!
And I can also not run the code in edit() directly after add(). Nothing happens. PLEASE HELP ME. I am going mad because I cannot see what is wrong!
I want to run the code associated with the buttons to update my JTable. Please tell me if there is something wrong in the code.
As I say - it works fine when I click the DELETE button, but on the others it doesn't work.
Please tell me if you need more information!
HOPE TO HEAR FROM SOMEONE BEFORE I KILL MYSELF OUT OF FRUSTRATION!!!!

Answer 1

if (event.getActionCommand() == "CLOSE") {
if (event.getActionCommand() == "ADD") {
if (event.getActionCommand() == "DELETE") {
if (event.getActionCommand() == "EDIT") {And these look highly dubious, too. Shouldn't you be doing
event.getActionCommand().equals("CLOSE")
etc.?
